Compliance to Transportation Restrictions for Lithium Batteries

1. Restriction for packing

The United Nations Dangerous Goods Regulations "Article 12" became effective from 2003. When
transporting lithium batteries with means subject to the UN Regulations, such as by air transport,
measures corresponding to the Regulations must be taken. The UN Regulations classify the batteries
as dangerous goods (Class 9) or not dangerous goods according to the lithium content.
To ensure safety during transportation, lithium batteries (battery unit) directly exported from Mitsubishi
are packaged in a dedicated container (UN package) for which safety has been confirmed. When the
customer is transporting these products with means subject to the UN Regulations, such as air
transport, the shipper must follow the details explained in the section "1-2 Handling by user".
1-1 Target products
The following Mitsubishi NC products use lithium batteries. The UN Regulations classify the batteries
as dangerous goods (Class 9) or not dangerous goods according to the lithium content. If the batteries
subjected to hazardous materials are incorporated in a device and shipped, a dedicated packaging
(UN packaging) is not required. However, the item must be packed and shipped following the Packing
Instruction 912 specified in the IATA DGR (Dangerous Goods Regulation) book.
Also, all lithium battery products incorporated in a machinery or device must be fixed securely in
accordance with the Packing Instruction 900 and shipped with protection in a way as to prevent
damage or short-circuits.

on the "Law of the People’s Republic of China on Import and Export Commodity Inspection" and
"Regulations on Implementation of the Import Commodities Subject to the Safety and Quality
Licensing System" enforced by the State Administration of Import and Export Commodity Inspection
(SACI) on import/export commodities, and the "CCEE Certification" (certification system based on
"Product Quality Certification Management Ordinance" set forth by the China Commission for
Conformity Certification of Electrical Equipment (CCEE) on commodities distributed through China.
CCIB Certification and CCEE Certification were merged when China joined WTO (November 2001),
and were replaced by the "China Compulsory Product Certification" (hereinafter, CCC Certification)
monitored by the State General Administration of Quality Supervision, Inspection and Quarantine
(AQSIQ) of the People's Republic of China.
The CCC Certification system was partially enforced from May 2002, and was fully enforced from May
2003. Target commodities which do not have CCC Certification cannot be imported to China or sold in
China. (Indication of the CCIB or CCEE mark has been eliminated from May 1, 2003.)

 Chapter 2 Wiring and Connection

1. Wiring work must be done by a qualified technician.

2. Wait at least 10 minutes after turning the power OFF and check the voltage
with a tester, etc., before starting wiring. Failure to observe this could lead
to electric shocks.
3. Securely ground the servo amplifier and servomotor with Class 3 grounding
DANGER or higher.
4. Wire the servo amplifier and servomotor after installation. Failure to observe
this could lead to electric shocks.
5. Do not damage, apply forcible stress, place heavy items or engage the cable.
Failure to observe this could lead to electric shocks.
6. Carry out insulation treatment to the connection part of the power supply
terminal. Failure to observe this could lead to electric shocks.

1. Correctly and securely perform the wiring. Failure to do so could lead to

runaway of the servomotor.
2. Do not mistake the terminal connections.
Failure to observe this item could lead to ruptures or damage, etc.
3. Do not mistake the polarity ( + , – ). Failure to observe this item could lead to
ruptures or damage, etc.

5. Electronic devices used near the servo amplifier may receive magnetic
obstruction. Reduce the effect of magnetic obstacles by installing a noise
filter, etc.
6. Do not install a phase advancing capacitor, surge absorber or radio noise
filter on the power supply wire (U, V, W) of the servomotor.
7. Do not modify this unit.
8. The CN1A, CN1B, CN2 and CN3 connectors on the front of the amplifier
have the same shape. If the connectors are connected incorrectly, faults
could occur. Make sure that the connection is correct.
9. When grounding the motor, connect to
the protective grounding terminal on the
servo amplifier, and ground from the
other protective grounding terminal.
(Use one-point grounding)
Do not separately ground the connected
motor and servo amplifier as noise could
be generated.

2-6 Connection of regenerative resistor

The servo amplifier has an internal regenerative resistor electronic thermal (software process), and
when overheating of the regenerative resistor is detected, an over-regeneration (alarm 30) is detected.
The parameters must be set correctly for the electronic thermal to operate correctly.
Refer to section "6-1-1 Combinations with servo amplifiers" for details on the combination of
parameter settings, external option regenerative resistor and servo amplifier capacity.

The parameters must be set to the regenerative resistor in use for the
CAUTION electronic thermal to operate correctly.

2-6-1 Connection of standard built-in regenerative resistor

The built-in regenerative resistor is connected by short-circuiting between the P and D terminals of the
control circuit terminal block (TE2). (Shipment state). Confirm that a short bar has been connected
between the P and D terminals.

MDS-B-SVJ2 (Note) The terminal block TE2 is on the top front of the
amplifier in the MDS-B-SVJ2-10 and -20.

The MDS-B-SVJ2-01 does not have a built-in regenerative resistor. If the load
inertia is small, there will be no problem with the capacitor regeneration
(regenerative resistance is not required as the circuit is charged with the
CAUTION capacitor in the amplifier). However, the overvoltage alarm (ALM33) will occur if
the load inertia is large. In this case, connect the external option regenerative
resistor. Refer to section "11-4 Selection of regenerative resistor" for details on
making a selection.

1. Always install a protective cover so that the cables, etc., do not directly
contact the regenerative resistor. Select the installation place so that foreign
matter (cutting chips, cutting oil, etc.) do not enter the regenerative resistor's
terminal block. A short-circuit between the P and C terminals could lead to
servo amplifier damage.
DANGER 2. The regenerative resistor generates heat of approximately 100°C (or higher,
depending on the installation conditions). Give sufficient consideration to
heat dissipation and installation position.
3. Use flame retardant wire or provide flame retardant treatment for the wire
connected to the regenerative resistor.

1. When installing on a wall, install the regenerative resistors vertically.

2. The regenerative resistor generates heat and will reach high temperatures if
the regeneration frequency is high. Do not install on wall surfaces
susceptible to heat.
CAUTION 3. When installing three resistors in a row, leave a space of 100mm or more
between each unit.
4. Always use twisted pair cable to connect to the servo amplifier, and keep
the length of the wiring to 5m or less. Refer to section "7-1 Selection of wire"
for details on selecting the wire.

2-6-3 Connection of external option regeneration resistance unit

Disconnect the short bar connected between the P and D terminals, and connect the option
regeneration resistor between the P and C terminals. The thermal protector terminals (G3, G4) are
used together with the electronic thermal to provide double-protection against overheating of the
regenerative resistor. Construct a sequence in which an emergency stop results when the current
stops flowing between G3 and G4.

2-7 Wiring of contactors

A contactor (magnetic contactor) is inserted in the main circuit power supply input (L1, L2, L3) of servo
amplifier, and the power supply input is shut off when an emergency stop or servo alarm occurs.
When an emergency stop or servo alarm occurs, the servo amplifier stops the motor using
deceleration control or a dynamic brake. The contactors cannot be shut off during deceleration control,
because the regeneration energy (MDS-C1-CV Series) is returned to the power supply, and the power
supply for deceleration must be held. Therefore, the CNC controls the contactors. The CNC confirms
that all axes are stopped, or confirms the dynamic brake operation. Then it outputs a shutoff command
for amplifiers that drive contactors.
If a converter unit (MDS-C1-CV/A-CR) is present when actually wiring the contactor, the drive is from
the converter unit. When a converter unit is not present, the drive is from the vertical axis or the servo
axis having the longest deceleration time constant. Note that the SVJ2-01 cannot control the
contactors unless an option resistor is externally connected.
Give consideration to the above, and examine the contactor drive method in the following order of
priority.

(Order of priority of the contactor drive method)

1. Using the contactor control output (MC1) of the converter unit.

2. Driving from the servo amplifier (MDS-B-SVJ2) of the vertical
axis (unbalanced axis).
3. Driving from the servo amplifier (MDS-B-SVJ2) having the
longest deceleration time constant.

1. The contactors cannot be driven other than from an amplifier or converter.

Undervoltage (alarm) may occur if the contactors are shut off at the same
time as an emergency stop occurs.
2. Do not directly shut off the contactors with an external sequence. They may
shut off faster than the emergency stop input, and the input power supply
may be shut off during the deceleration control or vertical axis drop
CAUTION prevention control. If this happens, an undervoltage alarm will occur, and
deceleration control or drop hold may not be possible. When
double-protecting, use an amplifier external emergency stop input.
(Refer to section "2-9 Wiring of an external emergency stop")
3. When driving contactors with the MDS-B-SVJ2-01, always externally install
a regenerative resistor. If there is no regenerative resistor installed, the
contactor fusion alarm will be incorrectly detected.

2-9 Wiring of external emergency stop

2-9-1 External emergency stop setting

Besides the main emergency stop input from the CNC bus line (CN1A, CN1B), double-protection
when an emergency stop occurs is possible by directly inputting an independent external emergency
stop to the servo amplifier. Even if the main emergency stop is not input for some reason, the
contactors will be shut off within 30 seconds after the external emergency stop is input.

1. When the SVJ2 controls the contactor, the external emergency stop input is
validated for the axis receiving the main circuit power supply from that
contactor. When the converter controls the contactor, use the external
emergency stop input of the converter.
POINT 2. So that the external emergency stop input will be an auxiliary input as much
as possible, always input the main emergency stop (NC bus line). An
external emergency stop error (alarm 55) will occur if only an external
emergency stop is input.

 Chapter 2 Wiring and Connection

2-9-2 External emergency stop operation sequences

If only an external emergency stop is input when external emergency stop valid is set in the
parameters (the main emergency stop is not input), an "In external emergency stop" (warning EA) will
be detected. At this time, the system itself does not enter an emergency stop status. (There will be no
deceleration control or dynamic brake stop).
If a contactor shutoff command is not issued from the CNC within 30 seconds after the external
emergency stop is input, the SVJ2 itself shuts off the contactors, and an external emergency stop
error (alarm 55) is detected. If the main emergency stop is input within 30 seconds, the warning EA
replaces the "In CNC emergency stop" (warning E7). A normal emergency stop status (warning E7)
will result if contactor shutoff commands from the CNC are further input.
Ready ON is possible even if an external emergency stop has been input when the emergency stop is
canceled, but an external emergency stop error (alarm 55) will occur after 30 seconds.

at the end of the shaft to mount the pulley onto the shaft. To Servom otor
install, first place the double-end stud into the shaft screw
holes, contact the coupling end surface against the washer,
and press in as if tightening with a nut. When the shaft does
not have a key way, use a frictional coupling, etc.
② When removing the pulley, use a pulley remover, and make Nut

sure not to apply an impact on the shaft. Pulley W asher

The brake plates may make a sliding sound when a servomotor with
magnetic brake is installed with the shaft facing upward, but this is
not a fault.
② In a situation where the detector cannon plug cannot be wired in the
same direction as the power supply wire, the motor is prepared so C
that the detector installation direction can be changed in 90°
increments, as shown in the drawing at the right. (Special
correspondence) Designate the motor direction when ordering. (Note D B
that HC-SF, HC-RF, HA-FF, HC-MF Series motors are not

CAUTION that the radial load (double the tension) generated from the timing belt
tension is less than the values shown in the table above.
4. In machines where thrust loads such as a worm gear are applied, carefully
consider providing separate bearings, etc., on the machine side so that
loads exceeding the tolerable thrust loads are not applied to the motor.

① A format based on IEC Standards (IP types) is displayed as the Oil or water
servomotor protective format (refer to "10-2-1 List of Specifications.").
However, these Standards are short-term performance specifications.
They do not guarantee continuous environmental protection
characteristics. Measures such as covers, etc., must be provided if
there is any possibility that oil or water will fall on the motor, or the
motor will be constantly wet and permeated by water. Note that
IP-type motors are not indicated as corrosion-resistant.

② When a gear box is installed on the servomotor, make sure that the oil level height from the center
of the shaft is higher than the values given below. Open a breathing hole on the gear box so that
the inner pressure does not rise. An oil seal is provided only on the HA-FF†C-UE and

1. The servomotors, including those having IP65, IP67 specifications, do not

have a completely waterproof (oil-proof) structure. Do not allow oil or water
to constantly contact the motor, enter the motor, or accumulate on the
motor. Oil can also enter the motor through cutting chip accumulation, so be
careful of this also.

3-2-6 Cable stress

1. Sufficiently consider the cable clamping method so that bending stress and
the stress from the cable's own weight is not applied on the cable
connection. Failure to observe this could lead to damage of the cable
sheath and electric shocks.
2. Make sure that the cable sheathes will not be cut by sharp cutting chips,
worn by contacting the machine corners, or stepped on by workers or
vehicles. Failure to observe this could lead to damage of the cable sheath
CAUTION and electric shocks.
3. In applications where the servomotor moves, make sure that excessive
stress is not applied on the cable.
If the detector cable and servomotor wiring are stored in a cable bear and
the servomotor moves, make sure that the cable bending section is within
the range of the optional detector cable.
Fix the detector cable and power cable enclosed with the servomotor.

The bending life of the detector cable is as shown below. Regard this with a slight allowance. If the
servomotor is installed on a machine that moves, make the bending radius as large as possible.

3-3 Noise measures

Noise includes that which enters the servo amplifier from an external source and causes the servo
amplifier to malfunction, and that which is radiated from the servo amplifier or motor and causes the
peripheral devices or amplifier itself to malfunction. The servo amplifier output is a source of noise as
the DC voltage is switched at a high frequency. If the peripheral devices or amplifier malfunction
because of the noise, measures must be taken to suppressed this noise. These measures differ
according to the propagation path of the noise.

(1) General measures for noise

• Avoid wiring the servo amplifier's power supply wire and signal wires in parallel or in a bundled
state. Always use separate wiring. Use a twisted pair shield wire for the detector cable, the
control signal wires for the bus cable, etc., and for the control power supply wire. Securely
ground the shield.
• Use one-point grounding for the servo amplifier and motor.

(2) Measures against noise entering from external source and causing servo amplifier to
malfunction
If a device generating noise is installed near the servo amplifier, and the servo amplifier could
malfunction, take the following measures.
• Install a surge killer on devices (magnetic contactor, relay, etc.) that generate high levels of
noise.
• Install a data line filter on the control signal wire.
• Ground the detector cable shield with a cable clamp.

(3) Measures against noise radiated from the servo amplifier and causing peripheral devices
to malfunction
The types of propagation paths of the noise generated from the servo amplifier and the noise
measures for each propagation path are shown below.

Measures
tion path
When devices such as instruments, receivers or sensors, which handle minute signals and
are easily affected by noise, or the signal wire of these devices, are stored in the same
panel as the servo amplifier and the wiring is close, the device could malfunction due to
airborne propagation of the noise. In this case, take the following measures.
(1) Install devices easily affected as far away from the servo amplifier as possible.
① ② ③ (2) Lay the signals wires easily affected as far away from the input wire with the servo
amplifier.
(3) Avoid parallel wiring or bundled wiring of the signal wire and power wire.
(4) Insert a line noise filter on the input/output wire or a radio noise filter on the input to
suppress noise radiated from the wires.
(5) Use a shield wire for the signal wire and power wire, or place in separate metal ducts.
If the signal wire is laid in parallel to the power wire, or if it is bundled with the power wire,
the noise could be propagated to the signal wire and cause malfunction because of the
magnetic induction noise or static induction noise. In this case, take the following measures.
(1) Install devices easily affected as far away from the servo amplifier as possible.
④ ⑤ ⑥
(2) Lay the signals wires easily affected as far away from the input wire with the servo
amplifier.
(3) Avoid parallel wiring or bundled wiring of the signal wire and power wire.
(4) Use a shield wire for the signal wire and power wire, or place in separate metal ducts.
If the power supply for the peripheral devices is connected to the power supply in the same
system as the servo amplifier, the noise generated from the servo amplifier could back flow
over the power supply wire and cause the devices to malfunction. In this case, take the
⑦
following measures.
(1) Install a radio noise filter on the servo amplifier's power wire.
(2) Install a line noise filter on the servo amplifier's power wire.
If a closed loop is structured by the peripheral device and servo amplifier's grounding wires,
⑧ the leakage current could penetrate and cause the devices to malfunction. In this case,
change the device grounding methods and the grounding place.

4-2-2 Limitations to electronic gear setting value

The servo amplifier has internal electronic gears. The command value from the NC is converted into a
detector resolution unit to carry out position control. The electronic gears are single gear ratios
calculated from multiple parameters as shown below. However, each value (ELG1, ELG2) must be
less than 32767.
If the value overflows, the initial parameter error (alarm 37) or error parameter No. 101 (2301 with
M50/M64 Series NC) will be output.
If an alarm occurs, the mechanical specifications and electrical specifications must be revised so that
the electronic gears are within the specifications range.

Reduced fraction of
ELG1 PC2 × RANG
= (reduced fraction)
ELG2 PC1 × PIT × IUNIT

RANG = RNG1 = RNG2

IUNIT = 2/NC command unit (μm)
1μm : IUNIT = 2, 0.1μm: IUNIT = 20

When the above is calculated, the following conditions must be satisfied.

ELG1 ≤ 32767
ELG2 ≤ 32767

If the electronic gears in the amplifier overflow, the alarm 37 or error parameter
POINT No. 101 (2301 with M50/M64 series NC) will be output.

5-2-2 Speed loop gain

(1) Setting the speed loop gain
The speed loop gain (SV005: VGN1) is an important parameter for determining the
responsiveness of the servo control. During servo adjustment, the highest extent that this value
can be set to becomes important. The setting value has a large influence on the machine cutting
precision and cycle time.
To adjust the VGN1 value, first obtain the standard VGN1 to judge how much VGN1 is required
for the machine load inertia.
The standard VGN1 is the value that corresponds to the size of the machine load inertia shown in
the graph in section 4-2-3. If the load inertia is not clear, estimate it using the following procedure.
① Set the VGN1 of a level where acceleration/deceleration operation is possible. (Set a slightly
lower value so resonance does not occur.)
② Set SV037 = 100, SV043 = 600, and SV044 = 0 in the servo parameters. Carry out a return
operation within the range where the axis can operate smoothly. At this time, set the
acceleration/deceleration time constant so the acceleration/deceleration torque equals or
exceeds (is 100% or higher than) the stall (rated) torque.
③ Observe the estimated disturbance using the D/A output, and increase the SV037 value until
the disturbance torque during acceleration/deceleration becomes smaller (cannot be
observed).
(The unbalance torque is observed as an estimated disturbance torque in the vertical and
slanted axes, so ignore this amount or set the torque offset (SV032) and adjust. The friction
torque is also observed in the same way for axes having a large amount of friction, but this
should be ignored. Refer to section "5-3-3 (3) Disturbance observer" for details.)
④ The SV037 setting where the disturbance torque becomes the smallest during the estimated
acceleration/deceleration is the machine's total load inertia magnification including the motor
inertia. Obtain the standard VGN1 from the graph in section 4-2-3 based on this value.
<When machine resonance does not occur at the standard VGN1>
Set the standard VGN1. Use the standard value if no problem (such as machine resonance)
occurs. If sufficient cutting precision cannot be obtained at the standard VGN1, do not raise the
VGN1 further above the standard value. Instead, use the disturbance observer and adjust.
Basically, there is no need to set a value higher than the standard value in VGN1.
<When machine resonance occurs at the standard VGN1>
Machine resonance is occurring if the shaft makes abnormal sounds when operating or stopping,
and a fine vibration can be felt when the machine is touched while stopped. Machine resonance
occurs because the servo control responsiveness includes the machine resonance points.
(Speed control resonance points occur, for example, at parts close to the motor such as ball
screws.) Machine resonance can be suppressed by lowering VGN1 and the servo control
responsiveness, but the cutting precision and cycle time are sacrificed. Thus, set a vibration
suppression filter and suppress the machine resonance (Refer to section "5-3-2 Vibration
suppression measures"), and set a value as close as possible to the standard VGN1. If the
machine resonance cannot be sufficiently eliminated even by using a vibration suppression filter,
then lower the VGN1.
No. Abbrev. Parameter name Explanation Setting range
SV005 VGN1 Speed loop gain Set this according to the motor inertia size. 1 ~ 999
If vibration occurs, adjust by lower the setting by 20% to 30% at a time.

The final VGN1 setting value should be 70 to 80% of the largest value at which
machine resonance does not occur.
POINT If the vibration suppression functions are used to suppress the resonance and
the VGN1 setting value is raised, the subsequent servo adjustment becomes
more favorable.

 Chapter 5 Adjustment

(2) Setting the speed loop lead compensation

The speed loop lead compensation (SV008: VIA) determines the characteristics of the speed loop
mainly at low frequency regions. 1364 is set as a standard, and 1900 is set as a standard during
SHG control. The standard value may drop as shown in the graph in section 4-2-3 in respect to
loads with a large inertia.
When the VGN1 is set lower than the standard value because the load inertia is large or because
machine resonance occurred, the speed loop control band is lowered. If the standard value is set
in the leading compensation in this status, the leading compensation control itself will induce
vibration. In concrete terms, a vibration of 10 to 20Hz could be caused during
acceleration/deceleration and stopping, and the position droop waveform could be disturbed
when accelerating to a constant speed and when stopped. (Refer to the following graphs.)
This vibration cannot be suppressed by the vibration suppression functions. Lower the VIA in
increments of 100 from the standard setting value. Set a value where vibration does not occur
and the position droop waveform converges smoothly. Because lowering the VIA causes a drop
in the position control's trackability, the vibration suppression is improved even when a
disturbance observer is used without lowering the VIA. (Be careful of machine resonance
occurrence at this time.)

Vibration waveform with leading compensation control Adjusted position droop waveform

If VIA is lowered, the position droop waveform becomes smooth and overshooting does not occur.
However, because the trackability regarding the position commands becomes worse, that amount
of positioning time and precision are sacrificed. VIA must be kept high (set the standard value) to
guarantee precision, especially in high-speed contour cutting (generally F = 1000 or higher). In
other words, a large enough value must be set in VGN1 so that the VIA does not need to be
lowered in machines aimed at high-speed precision. When adjusting, the cutting precision will be
better if adjustment is carried out to a degree where overshooting does not occur and a high VIA
is maintained, without pursuing position droop smoothness.
If there are no vibration or overshooting problems, the high-speed contour cutting precision can
be further improved by setting the VIA higher than the standard value. In this case, adjust by
raising the VIA in increments of 100 from the standard value.
Setting a higher VIA improves the trackability regarding position commands in machines for which
cycle time is important, and the time to when the position droop converges on the in-position
width is shortened.
It is easier to adjust the VIA to improve precision and cycle time if a large value (a value near the
standard value) can be set in VGN1, or if VGN1 can be raised equivalently using the disturbance
observer.

5-2-3 Position loop gain

(1) Setting the position loop gain

The position loop gain (SV003:PGN1) is a parameter that determines the trackability to the
command position. 33 is set as a standard. Set the same position loop gain value between
interpolation axes.
When PGN1 is raised, the settling time will be shortened, but a speed loop that has a
responsiveness that can track the position loop gain with increased response will be required. If
the speed loop responsiveness is insufficient, several Hz of vibration or overshooting will occur
during acceleration/deceleration. Vibration or overshooting will also occur when VGN1 is smaller
than the standard value during VIA adjustment, but the vibration that occurs in the position loop
is generally 10Hz or less. (The VIA vibration that occurs is 10 to 20Hz.) When the position control
includes machine resonance points (Position control machine resonance points occur at the
machine end parts, etc.) because of insufficient machine rigidity, the machine will vibrate during
positioning, etc. In either case, lower PGN1 and adjust so vibration does not occur.
If the machine also vibrates due to machine backlash when the motor stops, the vibration can be
suppressed by lowering the PGN1 and smoothly stopping.
If SHG control is used, an equivalently high position loop gain can be maintained while
suppressing these vibrations. To adjust the SHG control, gradually raise the gain from a setting
where 1/2 of a normal control PGN1 where vibration did not occur was set in PGN1. If the PGN1
setting value is more than 1/2 of the normal control PGN1 when SHG control is used, there is an
improvement effect in position control. (Note that for the settling time the improvement effect is at
1/ 2 or more.)

 Chapter 5 Adjustment

(3) SHG control (option function)

If the position loop gain is increased or feed forward control (CNC function ) is used to shorten the
settling time or increase the precision, the machine system may vibrate easily.
SHG control changes the position loop to a high-gain by stably compensating the servo system
position loop through a delay. This allows the settling time to be reduced and a high precision to
be achieved.
(Feature 1) When the SHG control is set, even if PGN1 is set to the same value as the
conventional gain, the position loop gain will be doubled.
(Feature 2) The SHG control response is smoother than conventional position control during
acceleration/deceleration, so the gain can be increased further with SHG control
compared to the conventional position control.
(Feature 3) With SHG control, a high gain is achieved so a high precision can be obtained during
contour control.
The following drawing shows an example of the improvement in roundness
characteristics with SHG control.

During SHG control even if the PGN1 setting value is the same, the actual position loop gain will
be higher, so the speed loop must have a sufficient response. If the speed loop response is low,
vibration or overshooting could occur during acceleration/deceleration in the same manner as
conventional control. If the speed loop gain has been lowered because machine resonance
occurs, lower the position loop gain and adjust.

The following items must be adjusted to adjust the cycle time. Refer to the Instruction Manuals
provided with each CNC for the acceleration/deceleration pattern.

②Clamp speed (clamp) : This will affect the maximum speed during cutting.

④In-position width (SV024) : This will affect each block's movement command end time.
⑤Position loop gain (SV003) : This will affect each block's movement command settling time.
(1) Adjusting the rapid traverse rate
To adjust the rapid traverse, the CNC axis specification parameter rapid traverse rate (rapid) and
acceleration/deceleration time constant (G0t†) are adjusted. The rapid traverse rate is set so that
the motor speed matches the machine specifications in the range below the maximum speed in the
motor specifications. For the acceleration/deceleration time constants, carry out rapid traverse
reciprocation operation, and set so that the maximum current command value at acceleration
/deceleration is within the range shown below. (Only when the rapid traverse rate is below the rated
speed.) Set the same value as the adjusted acceleration/deceleration time constant in the servo
parameter's deceleration control time constant (SV056:EMGt). (When deceleration control is set.)
For motors in which the maximum speed is greater than the rated speed (HC-SF, HC-RF, HC-MF,
HA-FF), the output torque is particularly restricted in the region at or above the rated speed.
When adjusting, watch the current FB waveform during acceleration/deceleration, and adjust so
that the torque is within the specified range. Be careful, as insufficient torque can easily occur
when the amplifier input voltage is low (170 to 190V), and an excessive error can easily occur
during acceleration/deceleration.

When using a range higher than the rated speed for the HC-SF, HC-RF, HA-FF
and HC-MF motor, take special care to the acceleration/deceleration torque. If
the amplifier input voltage is low (170 to 190V), an excessive error could occur
easily during acceleration/deceleration.
CAUTION When adjusting, decide the acceleration/deceleration time constant from the
motor speed - torque characteristics so that the acceleration/deceleration
torque is within the specifications range. The output torque at high speed
regions can be reduced by using the S-pattern (soft) acceleration/deceleration
function (NC function).

(2) Adjusting the cutting rate

To adjust the cutting rate, the CNC axis specification parameter clamp speed (clamp) and
acceleration/deceleration time constant (G1t†) are adjusted. The in-position width at this time
must be set to the same value as actual cutting.
• Determining the clamp rate and adjusting the acceleration/deceleration time constant
(Features) The maximum cutting rate (clamp speed) can be determined freely.
(Adjustment) Carry out cutting feed reciprocation operation with no dwell at the maximum
cutting rate and adjust the acceleration/deceleration time constant so that the
maximum current command value during acceleration/deceleration is within the
range shown below.
• Setting the step acceleration/deceleration and adjusting the clamp speed
(Features) The acceleration/deceleration time constant is determined with the position loop
in the servo, so the acceleration/deceleration F⊿T can be reduced.
(Adjustment) Set 1 (step) for the acceleration/deceleration time constant and carry out cutting
feed reciprocation operation with no dwell. Adjust the cutting feed rate so that
the maximum current command value during acceleration/deceleration is within
the range shown below, and then set the value in the clamp speed.

(3) Adjusting the in-position width

Because there is a response delay in the servomotor drive due to position loop control, a "settling

reaches 0.
The movement command in the next block is generally started after it is confirmed that the
machine has entered the "in-position width" range set for the machine.
The in-position width is effective even when the standard servo parameters are set. However, it
may follow the CNC parameters, so refer to the CNC Instruction Manual for the setting.

5-3-2 Vibration suppression measures

If vibration (machine resonance) occurs, it can be suppressed by lowering the speed loop gain
(VGN1). However, cutting precision and cycle time will be sacrificed. (Refer to "5-2-2 Speed loop
gain".) Thus, try to maintain the VGN1 as high as possible, and suppress the vibration using the
vibration suppression functions.
If the VGN1 is lowered and adjusted because vibration cannot be sufficiently suppressed with the
vibration suppression functions, adjust the entire gain (including the position loop gain) again.

<Examples of vibration occurrence>

• A fine vibration is felt when the machine is touched, or a groaning sound is heard.
• Vibration or noise occurs during rapid traverse.

value where resonance does not occur.

Suppress the vibration using the vibration suppression functions, and maintain
POINT the speed loop gain (SV005: VGN1) as high as possible.

(1) Notch filter 1

The resonance elimination filter will function at the set frequency. Use the D/A output function to
output the current feedback and measure the resonance frequency. Note that the resonance
frequency that can be measured is 0 to 500 Hz. For resonance exceeding 500 Hz, directly
measure the phase current with a current probe, etc.
When the notch filter is set, vibration may occur at a separate resonance frequency that existed
latently at first. In this case, the servo control is stabilized when the notch filter depth is adjusted
and the filter is adjusted so as not to operate more than required.

<Setting method>
1. Set the resonance frequency in the notch filter frequency 1 (SV038: FHz1).
2. If the machine starts to vibrate at another frequency, raise (make shallower) the notch filter
depth compensation value (SV033: SSF2.nfd), and adjust to the optimum value at which the
resonance can be eliminated.
3. When the vibration cannot be completely eliminated, use another vibration suppression

(3) Jitter compensation

The load inertia becomes extremely small if the motor position enters the machine backlash when
the motor is stopped. Because this means that an extremely large VGN1 is set for the load inertia,
vibration may occur.
Jitter compensation is the suppression of vibration occurring when the motor stops by ignoring the
backlash amount of speed feedback pulses when the speed feedback polarity changes.
Increase the number of ignored pulses by one pulse at a time, and set a value at which the
vibration can be suppressed. (Because the position feedback is controlled normally, there is no
worry of positional deviation.)
When an axis that does not vibrate is set, vibration could be induced, so take care.

(4) Adaptive filter (option function)

The servo amplifier detects the machine resonance point and automatically sets the filter constant.
Even if the ball screw and table position relation changes causing the resonance point to change,
the filter will track these changes.
Set the servo function selection 1 (SV027: SSF1) bit F to activate the adaptive filter.
If the vibration suppression effects do not appear even when the adaptive filter is activated,
change the "MAX current" display on the servo monitor, and confirm the operation status of the
adaptive filter. When the adaptive filter operation gain is 70% or more, adjust by gradually raising
the filter operation sensitivity (SV033: SSF2.afs) from the point where the sufficient filter results do
not appear.
Once converged, the adaptive filter constant is stored in the servo amplifier memory when the
CNC power is turned OFF. Even if the amplifier is turned OFF, it will start with the previously
saved constant when the power is turned ON next. To reset a filter constant that has been
converged once, set 0 in SSF1.aflt and stop the adaptive filter.

5-3-3 Improving the cutting surface precision

If the cutting surface precision is poor, it can be
improved by adjusting the speed loop gain or by Y
using the voltage dead zone compensation or
disturbance observer function.
<Examples of faults>
• The surface precision in the 45° direction of a
taper or arc is poor.
• The load fluctuation during cutting is large, causing X
vibration or surface precision defects to occur.
Adjust by raising the speed loop gain equivalently to improve cutting surface
precision, even if the measures differ. In this case, it is important how much the
POINT machine resonance can be controlled, so adjust making sufficient use of
vibration suppression functions.

(1) Adjusting the speed loop gain (VGN1)

If the speed loop gain is increased, the cutting surface precision will be improved but the machine
will resonate easily.
The final VGN1 setting should be approx. 70 to 80% of the maximum value where resonance
does not occur. (Refer to "5-2-2 (1) Setting the speed loop gain")
(2) Adjusting the speed loop leading compensation (VIA)
The VIA has a large influence on the position trackability, particularly during high-speed cutting
(generally F1000 or more). Raising the setting value improves the position trackability, and the
contour precision during cutting can be improved. For high-speed high-precision cutting machines,
adjust so that a value equal to or higher than the standard value can be set.
When VIA is set lower than the standard value and set to a value differing between interpolation
axes, the roundness may worsen (the circle may distort). This is due to differences occurring in
the position trackability between interpolation axes. The distortion can be improved by matching
the VIA with the smaller of the values. Note that because the position trackability is not improved,
the surface precision will not be improved.

compensation Adjust in increments of approx. 100.
Raise the VIA and adjust to improve the contour tracking precision in
high-speed cutting. If the position droop vibrates (10 to 20Hz), lower the
VIA and adjust.

(3) Voltage non-sensitive zone (Td) compensation (Compatible from software version C3)
With the PWM control of the inverter, a dead time
(non-energized time) is set to prevent short-circuits
caused by simultaneous energizing of the P side and Cutting
N side transistors having the same phase. The dead Motor torque
direction
time has a non-sensitive zone for particularly low ≒ 0
voltage commands. Thus, when feeding with a low Frictional
torque
speed and a low torque, the control may be unstable.
When an unbalanced axis is lowering, the frictional
torque and unbalance torque, and the frictional Balanced
torque and deceleration torque before the quadrant
changes during circle cutting, are balanced. The
motor output torque will be approximately zero, and Unbalance
the control accuracy may drop. In this case, the torque

generated.

 Chapter 5 Adjustment

(4) Disturbance observer

The disturbance observer can reduce the effect caused by disturbance, frictional resistance or
torsion vibration during cutting by estimating the disturbance torque and compensating it. It also is
effective in suppressing the vibration caused by speed leading compensation control.
<Setting method>
1. Adjust VGN1 to the value where vibration does not occur, and then lower it 10 to 20%.
2. Set the load inertia scale (SV037:JL) with a percentage in respect to the motor inertia of the
total load inertia.
3. Set the observer filter band (observer pole) in the disturbance observer filter frequency
(SV043:OBS1), and estimate the high frequency disturbance to suppress the vibration. Set
300 as a standard.
4. Set the observer gain in disturbance observer gain (SV044:OBS2). The disturbance observer
will function here for the first time. Set 100 first, and if vibration does not occur, increase the
setting by 50 at a time to increase the observer effect.
5. If vibration occurs, lower OBS1 by 50 at a time. The vibration can be eliminated by lowering
OBS2, but the effect of the disturbance observer can be maintained by keeping OBS2 set to a
high value.
<Load inertia measurement method>
If the load inertia is not clearly known, estimate it with the following method.
1. With the unbalance axis, set the torque offset (SV032:TOF). (Refer to "5-3-4 (2) Unbalance
torque compensation")
2. Set JL = 100, OBS1 = 600, and OBS2 = 0, and carry out a return operation within the range
where the axis can operate smoothly. At this time, set the acceleration/deceleration time
constant so the acceleration/deceleration torque equals or exceeds (is 100% or higher than)
the stall (rated) torque.
3. Observe the estimated disturbance torque using the D/A output, and increase JL until the
disturbance torque during acceleration/deceleration becomes small (cannot be observed).
Even when the torque offset is set and JL is an appropriate value, the friction torque amount
remains in the estimated disturbance torque of axes having a large amount of friction. As
shown in the graphs below, judge the setting value for JL having only the friction torque
remaining as the machine load inertia magnification.

5-3-4 Improvement of protrusion at quadrant changeover

The response delay (caused by non-sensitive band from friction, torsion, expansion/contraction,
backlash, etc.) caused when the machine advance direction reverses is compensated with the lost
motion compensation (LMC compensation) function.
With this, the protrusions that occur with the quadrant changeover in the DDB measurement method,
or the streaks that occur when the quadrant changes during circular cutting can be improved.

(1) Lost motion compensation (LMC compensation)

The lost motion compensation compensates the response delay during the reversal by adding the
torque command set with the parameters when the speed direction changes. There are two
methods for lost motion compensation. With the MDS-B-SVJ2, type 2 is used as a standard.
(The explanation for type 1 method is omitted because it is interchangeable with the old method.)
<Setting method>
1. Set the servo function selection 1 (SV027:SSF1) bit 9. (The LMC compensation type 2 will start).
2. Set the compensation amount with a stall % (rated current % for the general-purpose motor) unit
in the lost motion compensation 1 (SV016:LMC1). The LMC1 setting value will be used for
compensation in the positive and negative directions when SV041:LMC2 is 0.
3. If the compensation amount is to be changed in the direction to be compensated, set LMC2. The
compensation direction setting will be as shown below with the CW/CCW setting in the CNC
parameter. If only one direction is to be compensated, set the side not to be compensated as -1.

 Chapter 5 Adjustment

<Adjustment method>
First confirm whether the axis to be compensated is an unbalance axis (vertical axis, slant axis). If
it is an unbalance axis, carry out the adjustment after performing step "(2) Unbalance torque
compensation".
Next, measure the frictional torque. Carry out reciprocation operation (approx. F1000) with the
axis to be compensated and measure the load current % when fed at a constant speed on the
CNC servo monitor screen. The frictional torque of the machine at this time is expressed with the
following expression.
Frictional torque = (+ feed load current %) – (– feed load current %)
2
The standard setting value for the lost motion compensation 1 (LMC1) is double the frictional
torque above.

(Example)
Assume that the load current % was 25% in the + direction and –15% in the – direction when
JOG feed was carried out at approx. F1000. The frictional torque is as shown below, so 20% × 2
= 40% (LMC2 remains at zero, and compensation is carried out in both directions.) is set for
LMC1. (LMC2 is left set at 0.) With this setting, 40% compensation will be carried out when the
command reverses from the + direction to the - direction, and when the command reverses from
the – direction to the + direction.
25 – (–15) = 20%
2

For the final adjustment, measure the CNC sampling measurement (DBB measurement) or while
carrying out actual cutting. If the compensation amount is insufficient, increase LMC1 or LMC2 by
5% at a time. Note that if the setting is too high, biting may occur.

Compensation 0 Optimum Too high

1. When either parameter SV016: LMC1 or SV041: LMC2 is set to 0, the same
amount of compensation is carried out in both the positive and negative
direction with the setting value of the other parameter (the parameter not set to
0).
2. To compensate in only one direction, set -1 in the parameter (LMC1 or
LMC2) for the direction in which compensation is prohibited.
3. The value set based on the friction torque is the standard value for LMC
compensation. The optimum compensation value changes with the cutting
POINT conditions (cutting speed, cutting radius, blade type, workpiece material,
etc.). Be sure to ultimately make test cuts matching the target cutting and
determine the compensation amount.
4. When the disturbance observer has been started, the observer
compensation will also be effective on quadrant protrusions, so the optimum
compensation amount of the lost motion compensation will drop. Note that
the quadrant protrusions cannot be completely compensated with only the
disturbance observer.

 Chapter 5 Adjustment

(2) Unbalance torque compensation

If the load torque differs in the positive and negative directions such as with a vertical axis or slant
axis, the torque offset (SV032:TOF) is set to carry out accurate lost motion compensation.

<Setting method>
Measure the unbalance torque. Carry out reciprocation operation (approx. F1000) with the axis to
be compensated and measure the load current % when fed at a constant speed on the CNC
servo monitor screen. The unbalance torque at this time is expressed with the following
expression.
(+ feed load current %) – (– feed load current %)
Unbalance torque =
2

The unbalance torque value above is set for the torque offset (TOF).
If there is a difference in the protrusion amount according to the direction, make an adjustment
with LMC2. Do not adjust with TOF.
(Example)

Assume that the load current % was −40% in the + direction and −20% in the –
direction when JOG feed was carried out at approx. F1000. The unbalance torque is
as shown below, so −30% is set for TOF.

 Chapter 5 Adjustment

(3) Adjusting the lost motion compensation timing

If the speed loop gain has been lowered from the standard setting value because the machine
rigidity is low or because machine resonance occurs easily, or when cutting at high speeds, the
quadrant protrusion may appear later than the quadrant changeover point on the servo control. In
this case, suppress the quadrant protrusion by setting the lost motion compensation timing
(SV039: LMCD) to delay the LMC compensation.

<Adjustment method>
If a delay occurs in the quadrant protrusion in the circle or arc cutting as shown below in respect
to the cutting direction when CNC sampling measurement (DDB measurement) or actual cutting
is carried out, and the compensation appears before the protrusion position, set the lost motion
compensation timing (SV039:LMCD).
While measuring the arc path, increase LMCD by 10 msec at a time, to find the timing that the
protrusion and compensation position match.

When the LMCD is gradually raised, a two-peaked contour may occur at the motor FB position
DBB measurement. However, due to the influence of the cutter diameter in cutting such as end
milling, the actual cutting surface becomes smooth.
Because satisfactory cutting can be achieved even if this two-peaked contour occurs, consider
the point where the protrusion becomes the smallest and finest possible without over
compensating (bite-in) as the optimum setting.

(4) Adjusting for feed forward control

In LMC compensation, a model position considering the position loop gain is calculated based on
the position command sent from the CNC, and compensation is carried out when the feed
changes to that direction. When the CNC carries out feed forward (fwd) control, overshooting
equivalent to the operation fraction unit occurs in the position commands, and the timing of the
model position direction change may be mistaken. As a result, the LMC compensation timing may
deviate, or compensation may be carried out twice.
If feed forward control is carried out and the compensation does not operate correctly, adjust with
the non-sensitive band (SV040: LMCT) during feed forward control. In this non-sensitive band
control, overshooting of a set width or less is ignored. The model position direction change point
is correctly recognized, and the LMC compensation is correctly executed.
This parameter is meaningless when feed forward control is not being carried out.

<Adjustment method>
If the compensation timing deviates during feed forward control, increase the LMCT setting by
1μm at a time.
Note that 2μm are set even when the LMCT is set to 0.

Setting of the non-sensitive band (SV040: LMCT) during feed forward control is
POINT effective for improving overshooting compensation mis-operation during feed
forward control.

5-3-5 Improvement of overshooting

The phenomenon when the machine position goes past or exceeds the command during feed
stopping is called overshooting. Overshooting is compensated by overshooting compensation
(OVS compensation).
The phenomenon when the machine position exceeds the command during feed stopping is
called overshooting. Overshooting occurs due to the following two causes.
①Machine system torsion: Overshooting will occur mainly during rapid traverse settling
②Machine system friction: Overshooting will occur mainly during one pulse feed
Either phenomenon can be confirmed by measuring the position droop.

①Overshooting during rapid traverse settling ②Overshooting during pulse feed

(1) Overshooting compensation (OVS compensation)

In OVS compensation, the overshooting is suppressed by subtracting the torque command set in
the parameters when the motor stops. There are two types of OVS compensation. The standard
method for the MDS-B-SVJ2 is type 1.
OVS compensation type1 has a compensation effect for the overshooting during either rapid
traverse settling or pulse feed. Note that there is no compensation if the next feed command has
been issued before the motor positioning (stop). (Therefore, there is no compensation during
circle cutting.) There is also no compensation when the CNC is carrying out feed forward control.
To compensate overshooting during feed forward control, refer to the following section "(2)
Adjusting for feed forward control".

<Setting and adjustment methods>

① Set the servo function selection 1 (SV027:SSF1) bit A. (OVS compensation type 1 will start.)
② Observe the position droop waveform using the D/A output, and increase the overshoot
compensation 1 (SV031: OVS1) value 1% at a time. Set the smallest value where the
overshooting does not occur. If SV042:OVS2 is 0, the overshooting will be compensated in
both the forward/reverse directions with the OVS1 setting value.
③ If the compensation amount is to be changed in the direction to be compensated, set the +
direction compensation value in OVS1 and the – direction compensation value in OVS2. If only
one direction is to be compensated, set the side not to be compensated as -1. The
compensation direction setting will be as reversed with the CNC parameter CW/CCW setting.

In OVS compensation type 1, there is no compensation in the following cases.

1. There is no compensation if the next feed command has been issued before
POINT the motor positioning (stop). (There is no compensation in circle cutting.)
2. There is no compensation when the CNC is carrying out feed forward (fwd)
control.

5-21
 Chapter 5 Adjustment

(2) Adjusting for feed forward control

Use OVS compensation type 2 if overshooting is a problem in contour cutting during feed forward
control.
If OVS compensation type 2 is used to attempt to compensate overshooting, the overshooting
may conversely become larger, or projections may appear during arc cutting. This is because
overshooting equivalent to the operation fraction unit occurs in the position commands when the
CNC is carrying out feed forward control. Because of this, the OVS compensation recognizes a
change in the command direction, and executes the compensation in the opposite direction.
If the compensation is in the opposite direction when carrying out feed forward control, adjust with
the non-sensitive band (SV040: LMCT) during feed forward control in the same way as during
LMC compensation. By ignoring overshooting of a set width in the LMCT or less, the command
direction change point is correctly recognized, and the OVS compensation is correctly executed.
Because this phenomenon is due to the same causes as the phenomenon during LMC
compensation, it is adjusted with the same parameters. The adjustment is completed if the correct
setting is possible during whichever compensation.
This parameter is insignificant when feed forward control is not used.
<Adjustment method>
If the OVS compensation is carried out in reverse during feed forward control, increase the LMCT
setting by 1μm at a time.
Note that 2μm are set even when the LMCT is set to 0.

OVS compensation type 2 is used if overshooting is a problem during feed

POINT forward control.

(2) Acceleration feed forward

Vibration may occur at 10 to 20 Hz during acceleration/deceleration when a short time constant of
30 msec or less is applied, and a position loop gain (PGN1) higher than the general standard
value or SHG control is used. This is because the torque is insufficient when starting or when
starting deceleration, and can be resolved by setting the acceleration rate feed forward gain
(SV015:FFC). This is also effective in reducing the peak current (torque).
While measuring the current command waveform, increase FFC by 50 to 100 at a time and set
the value where vibration does not occur.

Acceleration feed forward gain means that the speed loop gain during acceleration/deceleration is
raised equivalently. Thus, the torque (current command) required during acceleration/deceleration
starts sooner. The synchronization precision will improve if the FFC of the delayed side axis is
raised between axes for which high-precision synchronous control (such as synchronous tap
control and superimposition control).

5-4 Setting for emergency stop

The emergency stop referred to here indicates the following states.
① When the external emergency stop was input (including other axis alarms)
② When the CNC power down was detected
③ When a servo alarm was detected

5-4-1 Deceleration control

This MDS-B-SVJ2 servo amplifier decelerates the motor according to the set time constant in the
ready ON state even when an emergency stop occurs, and activates the dynamic brakes after
stopping and turning ready OFF. This series of controls is called deceleration control. In the
MDS-B-SVJ2, deceleration control is the standard method of stopping during an emergency stop.
<Features>
① When the load inertia is large, deceleration and stop are possible with a short time constant
using the dynamic brakes. (Stopping is possible with a basically normal acceleration/
deceleration time constant.)
② When used in a transfer line, etc., stopping with little shock is possible by setting a long time
constant.
(1) Setting the deceleration control time constant
The time to stopping from the rapid traverse rate (rapid: axis specification parameter) is set in the
deceleration time constant at emergency stop (SV056: EMGt). A position loop step stop is carried
out when 0 is set.
When linear (straight line) acceleration/deceleration is selected for the rapid traverse, the same
value as the acceleration/deceleration time constant (G0tL) becomes the standard value. When
another acceleration/deceleration pattern is selected, set the rapid traverse to linear
acceleration/deceleration. Adjust to the optimum acceleration/deceleration time constant, and set
that value as the standard value.
<Operation>
When an emergency stop occurs, the motor will decelerate at the same inclination from each
speed, and will change to the dynamic brakes at 60 r/min or less. If the power fails, etc., the
dynamic brakes will be applied during the deceleration control. When the motor brakes are
controlled with amplifier output while using an unbalanced axis, the motor brake control output
operates simultaneously with the changeover to the dynamic brakes.

1. The deceleration will not be controlled when a servo alarm that uses the
dynamic brake stopping method occurs. Stopping is by the dynamic brake
method regardless of the parameter setting.
POINT 2. When a power failure occurs, the stopping method may change over to a
dynamic brake stop during deceleration control if the deceleration time
constant is set comparatively long. This is because of low bus voltage in the
amplifier.

5-26
 Chapter 5 Adjustment

If the deceleration time constant at emergency stop (EMGt) is set longer than
the acceleration/deceleration time constant, the overtravel point (stroke end
CAUTION point) may be exceeded.
A collision may be caused on the machine end, so be careful.

(2) Dynamic brake stop

When an emergency stop occurs, it is possible to have the machine stop from the beginning
using a dynamic brake without controlling the deceleration. Set bit 0 in the servo specification
selection (SV017: SPEC) to select a dynamic brake stop.
In a dynamic brake stop, the dynamic brakes operate at the same time the emergency stop
occurs, and the motor brake output also operates at the same time.

5-4-2 Vertical axis drop prevention control

(1) Vertical axis drop prevention control
The vertical axis drop prevention control is a function that prevents the vertical axis from dropping
due to a delay in the brake operation when an emergency stop occurs. The servo ready OFF will
be delayed by the time set in the parameter from when the emergency stop occurs. Thus, the
no-control time until the brakes activate can be eliminated.

<Setting and adjustment methods>

Set the time to delay the ready OFF in the vertical axis drop prevention time (SV048:EMGrt).
Read the current position on the CNC screen, and apply the emergency stop. Set the minimum
delay time where the axis does not drop.

1. This control will not function if the dynamic brake stop is selected with the
servo specification selection (SV017: SPEC).
2. This control will not function if an alarm for which the dynamic brakes are
POINT set as the stopping method occurs in an axis where vertical axis drop
prevention control is being carried out.
3. A drop amount of several μm to 10μm will remain due to the brake play.

1. Do not set a vertical axis drop prevention time longer than required. The
servo control and brakes could collide causing an overload alarm or
amplifier damage. There is no problem if the duplicate time is within
CAUTION 100msec.
2. During a power failure, vertical axis drop prevention control (including
deceleration control) exceeding 100msec cannot be guaranteed. The
control will change to the dynamic brakes.

(2) Vertical axis lift up control

Even when the vertical axis drop prevention control is applied, the axis will drop several µm due
to the mechanical play of the motor brakes. This function raises the axis, before the brakes are

5-5 Collision detection

The purpose of the collision detection function is to quickly detect a collision and decelerate to a stop.
This suppresses the excessive torque generated to the machine tool, and suppresses the occurrence
of an abnormality. Impact during a collision cannot be prevented even when the collision detection
function is used, so this function does not guarantee that the machine will not break and does not
guarantee the machine accuracy after a collision. Thus, the conventional caution is required to prevent
machine collisions from occurring.

(1) Collision detection method 1

The required torque is calculated from the position Collision
command issued from the NC. The disturbance detection level Detection
torque is calculated from the difference with the setting alarm

After decelerating to a stop, the alarm 58 or 59 will
occur, and the system will stop.
The collision detection level for rapid traverse (G0) is set with TLMT: SVC060. The collision
detection level for cutting feed (G1) is set to 0 to 7-fold (SV053.clG1) based on the collision
detection level for rapid traverse. If 0 is set for clG1, the collision detection method 1 will not
function during cutting feed. If 0 is set for TLMT: SV060, all collision detections (method 1 and
method 2) will not function.

(2) Collision detection method 2

When the current command reaches the motor's maximum current, the axis will decelerate to a
stop with at 80% of the motor's maximum torque or the parameter current limit value (torque limit
value), whichever is smaller. After decelerating to a stop, the alarm 5A will occur, and the system
will stop. If the acceleration/deceleration time constant is short and incorrect detections are made
easily during normal operation, increase the acceleration/deceleration time constant and adjust so
that the current during acceleration is not saturated (so that the maximum current is not reached).
If the acceleration/deceleration time constant cannot be increased, set parameter SV035.bit F:
(SSF4.cl2n) to 1 to ignore the collision detection method 2.

The collision detection function does not guarantee safety or machine accuracy
CAUTION during a collision. Thus, the conventional caution is required to prevent
machine collisions from occurring.

<Setting and adjustment methods>

1. Confirm that SHG control is being used. The collision detection function is valid only during
SHG control.
2. Measure the unbalance torque, and set in the torque offset (SV32: TOF). Refer to the section
"5-3-4 (2) Unbalance torque compensation" for details on measuring the unbalance torque.
3. Measure the frictional torque, and set in the frictional torque (SV045: TRUB). Refer to the
section "5-3-4-91) Lost motion compensation" for details on measuring the frictional torque.
4. Measure the load inertia rate, and set in the collision detection torque estimating gain (SV059:
TCNV). Measure the load inertia rate with the following method.

The load inertia rate can also be measured using the disturbance observer function. Refer to section "5-3-3 (4)
Disturbance observer".

5. If the acceleration/deceleration time is short and the current is easily saturated, set SV035.bitF
(cl2n) to 1, and ignore the collision detection method 2.
6. Set the collision detection level.

Feed Detection level setting Explanation

First set SV060: TLEV = 100, and carry out no-load operation at the
maximum rapid traverse feed rate. If an alarm does not occur, lower the
setting by 10, and if an alarm occurs, raise the setting by 20. Set a value
G0 SV060
that is 1.5 times the limit value where the alarm does not occur.
If SV034.mon is set to 7, the maximum disturbance torque will appear on
the NC servo monitor, so adjust using this value as a reference.
The detection level for G1 is set as an integer-fold of the G0 detection
level. Calculate the maximum cutting load, and adjust the SV035.clG1
G1 SV060×clG1 (SV035)
setting value so that the detection level is larger than the maximum cutting
load.

1. The SHG control must be validated to use the collision detection function or
to carry out load inertia measurement operation.
2. If the unbalance torque (SV032) or frictional torque (SV045) setting values
change during the load inertia measurement, the measurement results will
POINT change. The unbalance torque and frictional torque must be set as
accurately as possible to carry out accurate measurements.
3. Set the detection level with an allowance to avoid incorrect detections.
4. When SV060 is set to 0, all collision detection functions will be invalidated.

Wait at least 10 minutes after turning the power OFF, confirm that the
CHARGE lamp has gone out, and check the voltage with a tester, etc., before
DANGER connecting the options or peripheral devices. Failure to observe this could lead
to electric shocks.

1. Always use the designated options. Failure to observe this could lead to
faults or fires.
2. Take care to the installation environment so that cutting chips and oil, etc.,
CAUTION do not get on the optional regenerative resistor. A short-circuit fault could
occur at the resistor's terminal block, and the oil that adheres could burn
leading to fires.

1. On January 1, 2003, new United Nations requirements, "United Nations

Dangerous Goods Regulations Article 12", became effective regarding the
transportation of lithium batteries. The lithium batteries are classified as
hazardous materials (Class 9) depending on the unit. (Refer to
"Transportation restrictions for lithium batteries".)
2. The lithium battery must be transported according to the rules set forth by
the International Civil Aviation Organization (ICAO), International Air
Transportation Association (IATA), International Maritime Organization
(IMO), and United States Department of Transportation (DOT), etc. The
packaging methods, correct transportation methods, and special regulations
are specified according to the quantity of lithium alloys. The battery unit
CAUTION exported from Mitsubishi is packaged in a container (UN approved part)
satisfying the standards set forth in this UN Advisory.
3. To protect the absolute value, do not shut off the servo drive unit control
power supply if the battery voltage becomes low (warning 9F).
4. Contact the Service Center when replacing the MDS-A-BT Series and cell
battery.
5. The battery life (backup time) is greatly affected by the working ambient
temperature. The above data is the theoretical value for when the battery is
used 8 hours a day/240 days a year at an ambient temperature of 25°C.
Generally, if the ambient temperature increases, the backup time and useful
life will both decrease.

6-4-3 Flexible conduits

Basically, splash proofing can be ensured if cab-tire cable and connectors with IP65 or higher
specifications are used. However, to further improve the oil resistance (chemical resistance to oil),
weather resistance (resistance to the environment when used outdoors, etc.), durability, tensile
strength, flattening strength, etc., run the cable through a flexible conduit when wiring.
The following shows an example of a flexible conduit. Contact the connector maker for more
information.

(3) Cable protection tube (noise countermeasure)

If influence from noise is unavoidable, or further noise resistance is required, selecting a flexible
tube and running the signal cable through this tube is effective. This is also an effective
countermeasure for preventing the cable sheath from being cut or becoming worn.
A cable clamp (MS3057) is not installed on the detector side, so be particularly careful of
broken wires in applications involving bending and vibration.

(Example 1)
The circuit protector is selected for the MDS-B-SVJ2-10 with 3 HC102 axes and an MDS-B-SPJ2-75
axis connected.
Because there are 1kW × 3 = 3kW on the SVJ2 side, 20A is selected from the table for the circuit
protector rated current.
40A is selected from the table for the SPJ2-75 rated current.
Therefore, the total rated current is 60A, and the NF60-CP3P60A is selected.

(Example 2)

The circuit protector is selected for the MDS-B-SVJ2-20 with 2 HC202 axes and an MDS-B-CR-90
connected.
Because there are 2kW × 2 = 4kW on the SVJ2 side, 30A is selected from the table for the circuit
protector rated current.
50A is selected from the table for the MDS-B-CV-90 rated current.
Therefore, the total rated current is 80A. The circuit protector is separated from converter unit,
and the NF30-CS3P30A is selected for the SVJ2. (Refer to the "MDS-A/B Series Specifications
Manual" for details on selecting the converter circuit protector.)

Install independent circuit protectors and contactors as the SVJ2 main circuit
power supply if the total current capacity exceeds 60A when the power supply
is shared between the converter and a large capacity SPJ2 spindle amplifier.
DANGER Circuit protectors may not operate for short-circuits in small capacity amplifiers
if they are shared with a large capacity unit, and this could cause fires. For the
SVJ2, use an NF60 type or lower capacity breaker.

7-3 Selection of contactor

Select the contactor based on section "7-3-1 Selection from rush current" when the system connected
to the contactor to be selected is an MDS-B-SVJ2 and 3.7kW or less MDS-B-SPJ2 spindle amplifier.
When a converter unit or 5.5kW or more MDS-B-SPJ2 spindle amplifier is included, calculate both the
capacities in sections "7-3-1 Selection from rush current" and "7-3-2 Selection from input current", and
select the larger of the two capacities.

The contactors can be directly driven from the SVJ2 contactor control output

7-4-3 Surge absorber

When controlling a magnetic brake of a servomotor in DC OFF circuit, a surge absorber must be
installed to protect the relay contacts and brakes. Commonly a varistor is used.
(1) Selection of varistor
When a varistor is installed in parallel with the coil, the surge voltage can be adsorbed as heat to
protect a circuit. Commonly a 120V product is applied. When the brake operation time is delayed,
use a 220V product. Always confirm the operation with an actual machine.

(2) Specifications
Select a varistor with the following or equivalent specifications. To prevent short-circuiting, attach
a flame resistant insulation tube, etc., onto the leads as shown in the following outline dimension

9-1 Overload protection characteristics

The servo amplifier has an electronic thermal relay to protect the servomotor and servo amplifier from
overloads. The operation characteristics of the electronic thermal relay when standard parameters
(SV021=60, SV022=150) are set shown below.
If overload operation over the electronic thermal relay protection curve shown below is carried out,
overload 1 (alarm 50) will occur. If the maximum current is commanded at 95% or higher continuously
for one second or more due to a machine collision, etc., overload 2 (alarm 51) will occur.
The HA-FF053/13 and HC-MF053/13 have characteristics different from the other motors.

9-2-1 Servo amplifier calorific value

The servo amplifier calorific value is determined from the following table by the motor with which the
servo amplifier is combined. The calorific value for the actual machine will be a value between the
calorific values at the stall torque (at the rated torque) and the zero torque according to the frequency
during operation. Consider the worst usage conditions for the thermal design of the fully closed type
control panel, and use the values given below. Even when the servomotor is run below the maximum
speed, the servo amplifier calorific value will not change if the generated torque is the same.

The required heat radiation area will also differ according to the conditions in the control panel. If the
convection in the control panel is poor, effective heat radiation will not be possible. In this case, when

9-3 Magnetic brake characteristics

1. The axis will not be mechanically held even when the dynamic brakes are
used. If the machine could drop when the power fails, use a servomotor with
magnetic brakes or provide an external brake mechanism as holding means
to prevent dropping.
2. The magnetic brakes are used for holding, and must not be used for normal
braking. There may be cases when holding is not possible due to the life or
machine structure (when ball screw and servomotor are coupled with a
timing belt, etc.). Provide a stop device on the machine side to ensure
CAUTION safety. When releasing the brakes, always confirm that the servo is ON first.
Sequence control considering this condition is possible if the amplifier motor
brake control signal (MBR) is used.
3. When operating the brakes, always turn the servo OFF (or ready OFF).
When releasing the brakes, always confirm that the servo is ON first.
Sequence control considering this condition is possible if the amplifier motor
brake control signal (MBR) is used.
4. When the vertical axis drop prevention function is used, the drop of the
vertical axis during an emergency stop can be suppressed to the minimum.

9-3-1 Motor with magnetic brakes

(1) Types
The motor with magnetic brakes is set for each motor. The "B" following the standard motor type
indicates the motor with brakes.

(2) Applications
When this type of motor is used for the vertical feed axis in a machining center, etc., slipping and
dropping of the spindle head can be prevented even when the hydraulic balancer's hydraulic
pressure reaches zero when the power turns OFF. When used with a robot, deviation of the
posture when the power is turned OFF can be prevented.
When used for the feed axis of a grinding machine, a double safety measures is formed with the
deceleration stop (dynamic brake stop), and the risks of colliding with the grinding stone and
scattering can be prevented.
This motor cannot be used for purposes other than holding and braking during a power failure
(emergency stop). (This cannot be used for normal deceleration, etc.)

(3) Features
① The magnetic brakes use a DC excitation method, thus:
• The brake mechanism is simple and the reliability is high.
• There is no need to change the brake tap between 50 Hz and 60 Hz.
• There is no rush current when the excitation occurs, and shock does not occur.
• The brake section is not larger than the motor section.
② The magnetic brakes are built into the motor, and the installation dimensions are the same as
the motor without brakes.

Notes:
1. There is no manual release mechanism. If handling is required such as during the machine core alignment
work, prepare a separate 24 VDC power supply, and electrically release the brakes.
2. These are the values added to the servomotor without brakes.
3. This is the value for 20°C at the initial attraction gap.
4. The brake gap will widen through brake lining wear caused by braking. However, the gap cannot be adjusted.
Thus, the brake life is reached when adjustments are required.
5. The internal power output (VDD) 24 VDC for digital output cannot be used. Always prepare a separate power
supply.
6. A leakage flux will be generated at the shaft end of the servomotor with magnetic brakes.
7. When operating in low speed regions, the sound of loose brake lining may be heard. However, this is not a
problem in terms of function.

9-3-3 Magnetic brake power supply

1. The internal power supply output (VDD) 24 VDC as digital output cannot be
used for the magnetic brake release power supply. Always prepare an
external release power supply dedicated for the magnetic brakes.
CAUTION 2. Always install a surge absorber on the brake terminal when using DC OFF.
3. Do not connector or disconnect the cannon plug while the brake power is
ON. The cannon plug pins could be damaged by sparks.

(1) Brake excitation power supply

① Prepare a brake excitation power supply that can accurately ensure the attraction current in
consideration of the voltage fluctuation and excitation coil temperature.
② The brake terminal polarity is random. Make sure not to mistake the terminals with other
circuits.

(2) Brake excitation circuit

(a) AC OFF and (b) DC OFF can be used to turn OFF the brake excitation power supply (to apply
the brakes).

(a) AC OFF
The braking delay time will be longer, but the excitation circuit will be simple, and the relay cut
off capacity will be smaller.
(b) DC OFF
The braking delay time can be shortened, but a surge absorber will be required and the relay
cut off capacity will increase.
<Cautions>
• Provide sufficient DC cut off capacity at the contact.
• Always use a serge absorber.
• When using the cannon plug type, the surge absorber will be further away, so use shielded
wires between the motor and surge absorber.

9-4 Dynamic brake characteristics

When an emergency stop occurs such as that due to a servo alarm detection, the motor will stop with
the deceleration control at the standard setting. However, by setting the servo parameter (SV017:
SPEC), the dynamic brake stop can be selected. If a servo alarm that cannot control the motor occurs,
the dynamic brakes stop the servomotor regardless of the parameter setting.

9-4-1 Deceleration torque

The dynamic brakes use the motor as a generator, and obtains the deceleration torque by consuming
that energy with the dynamic brake resistance. The characteristics of this deceleration torque have a
maximum deceleration torque (Tdp) regarding the motor speed as shown in the following drawing.
The torque for each motor is shown in the following table.

11-1 Outline

11-1-1 Servomotor
It important to select a servomotor matched to the purpose of the machine that will be installed. If the
servomotor and machine to be installed do not match, the motor performance cannot be fully realized,
and it will also be difficult to adjust the parameters. Be sure to understand the servomotor
characteristics in this chapter to select the correct motor.

(1) Motor inertia

The servomotor series is mainly categorized according to the motor inertia size. The features in
Table 11-1 are provided according to the motor inertia size.

Table 11-1 Motor inertia

Motor model Medium inertia motor Low inertia motor
Motor type HC†, HA†N, HC-SF HC†R, HC-RF, HA-FF, HC-MF
Inertia The flange size is large. The flange size is small.
The inertia is comparatively large. The inertia is small.
Acceleration/deceleration The acceleration/deceleration time Acceleration/deceleration is possible
constant does not change much even for with a short time constant in respect to
a low inertia load. low inertia loads.
The effect of the motor inertia is large. The effect of the motor inertia is small.
Installation The motor size in respect to the output The motor size in respect to the output
capacity is large, and the installation capacity is small, and the installation
space is large. space is smaller.
Disturbance characteristics The effect of disturbance is small. The effect of disturbance is large.
Speed fluctuation The effect of the torque ripple and The effect of the torque ripple and
cogging torque is small, and speed cogging torque is large, and speed
fluctuation does not occur easily. fluctuation occurs easily.
Suitability Suitable for high precision interpolation Suitable for high speed high frequency
control positioning

Select a medium inertia motor when interpolation precision is required, or for machines having a
large load inertia. Select a low inertia motor when a shorter positioning time is required by
machines having a small amount of inertia. In general, use HC† and HA†N motors for axis
control of machine tools, and use HC†R, HC-SF, HC-RF, HA-FF and HC-MF motors for machine
tool auxiliary axes, peripheral axes, and general industrial machine positioning.
The servomotor has an optimum load inertia scale. If the load inertia exceeds the optimum range,
the control becomes unstable and the servo parameters become difficult to adjust. When the load
inertia is too large, decelerate with the gears (The motor axis conversion load inertia is
proportional to the square of the deceleration ratio.), or change to a motor with a large inertia.

The HC-MF motor has the lowest inertia. This series pursues low inertia motor
performance. To realize the proper acceleration/deceleration performance of
POINT the low inertia motor, set the load inertia to within five times of the motor inertia.
If the load inertia ratio increases, the control stability will deteriorate, and in the
end the positioning will take longer.

11-2
 Chapter 11 Selection

(2) Rated speed

Even with motors having the same capacity, the rated speed will differ according to the motor.
The motor's rated output is designed to be generated at the rated speed, and the output P (W) is
expressed with expression (11-1). Thus, even when the motors have the same capacity, the rated
torque will differ according to the rated speed.

P = 2πNT (W) .................................................. (11-1)

N : Motor speed (1/sec)

T : Output torque (N⋅m)

In other words, even with motors having the same capacities, the one with the lower rated speed will
generate a larger torque. When actually mounted on the machine, if the positioning distance is short
and the motor cannot reach the maximum speed, the motor with the lower rated speed will have a
shorter positioning time. When selecting the motor, consider the axis stroke and usage methods, and
select the motor with the optimum rated speed.
If the maximum speed is larger than the rated speed, such as with the HC-SF, HC-RF, HA-FF or
HC-MF, the continuous characteristic torque over the rated speed will be lower than the rated torque
due to the relation of the expression above.

11-1-2 Regeneration methods

When the servomotor decelerates, rotating load inertia or the operation energy of the moving object is
returned to the servo amplifier through the servomotor as electrical power. This is called
"regeneration". The three general methods of processing regeneration energy are shown below.

Table 11-2 Servo amplifier regeneration methods

Regeneration method Explanation
1. Condenser regeneration This is a regeneration method for small-capacity amplifiers. The
method regeneration energy is charged to the condenser in the amplifier, and this
energy is used during the next acceleration.
The regeneration capacity decreases as the power supply voltage becomes
higher.
2. Resistance regeneration If the condenser voltage rises too high when regenerating with the
method condenser only, the regenerative electrical power is consumed using the
resistance. If the regeneration energy is small, it will only be charged to the
condenser. Because regeneration energy becomes heat due to resistance,
heat radiation must be considered.
In large capacity servo amplifiers the regenerative resistance becomes
large and this is not practical.
3. Power supply regeneration This is a method to return the regeneration energy to the power supply. The
method regeneration energy does not become heat as in regenerative resistance.
(Heat is generated due to regeneration efficiency problems.)
The circuit becomes complicated, but in large capacity servo amplifiers
having large regeneration capacity this method is more advantageous than
resistance regeneration.

The condenser regeneration method and resistance regeneration method are used in the
MDS-B-SVJ2. For amplifiers (SVJ2-03 and higher) driving motors of 200W or more, the regenerative
resistor is mounted in the amplifier as a standard. If the regenerative capacity becomes large, an
option regenerative resistor is connected externally to the amplifier. (Combined use with the built-in
resistor is not possible.)
When the power supply regeneration method is used, consider using the MDS-C1-V1/V2 +
MDS-C1-CV Series.

The MDS-B-SVJ2-01 (100W) uses condenser regeneration as a standard. A

POINT built-in regenerative resistor is not mounted.

11-2-2 Servomotor precision

The control precision of the servomotor is determined by the detector resolution, motor characteristics
and parameter adjustment. This section examines the following four types of servomotor control
precision when the servo parameters are adjusted. When selecting a servo, confirm that these types
of precision satisfy the machine specifications before determining the servomotor series.

(1) Theoretic precision: Δε

This value is determined by the motor detector precision, and is the value obtained by dividing the
movement amount (ΔS) per motor rotation by the detector resolution (RNG).
(2) Positioning precision : Δεp
This is the precision outline that affects the machine targeted for positioning, and expresses the
machine's positioning precision.
When the motor is a single unit, this is determined by the detector resolution and matches with
the theoretic precision Δεp. When the motor is actually installed on a machine, the positioning
precision Δεp becomes 1 to 2 times the theoretic precision Δε. This is due to the effect on the
motor control by the machine rigidity, etc. Furthermore, the value to which the error from the
motor shaft to the machine end is added becomes the actual machine end positioning precision.
For machines requiring accurate positioning precision at the machine end, use the
MDS-C1-V1/V2 Series servo amplifier capable of scale feedback input.
(3) Surface precision during machining : Δεv
This is the precision outline that affects the machine tools, etc., which are important factors in the
machine operation path and interpolation functions. It also affects the surface roughness of the
machining surface. The machining surface roughness is affected by elements caused by the
motor's electrical characteristics (torque ripple, etc.) and mechanical characteristics (cogging
torque, etc.). In the NC unit feed axis motor (HC†, HA†N) those torque characteristics are
excellent, and higher precision machining is possible than that of other motors. Because the
effects of torque ripple and cogging torque are relatively smaller in motors with large amounts of
inertia, the motor with the larger inertia of two identical capacity motors will be more
advantageous for surface precision. Due to the effects of differences in characteristics of the
motor itself, the surface precision during machining will differ greatly according to the motor
series.
(4) Absolute position repeatability : Δεa
This is the precision outline that affects the absolute position system machine, and expresses the
repeatability of the position before the power was shut off and the position when the power is
turned on again.
With the single motor unit, the precision is 1 to 2 times the theoretic precision Δε. Note that the
absolute position repeatability Δεa is the difference from when the power was turned off last and
returned on. This error is not cumulated.

precision at the motor end during actual machining by adding the machine precision to the value in the

11-3 Selection of servomotor capacity

The following three elements are used to determine the servomotor capacity.
1. Load inertia ratio
2. Short time characteristics (acceleration/deceleration torque)
3. Continuous characteristics (continuous effective load torque)

Carry out appropriate measures, such as increasing the motor capacity, if any of the above conditions
is not fulfilled.

11-3-1 Load inertia ratio

Each servomotor has an appropriate load inertia ratio (load inertia/motor inertia). The control becomes
unstable when the load inertia ratio is too large, and parameter adjustment becomes difficult. It
becomes difficult to improve the surface precision in the feed axis, and the positioning time cannot be
shortened in the position axis because the settling time is longer.
If the load inertia ratio exceeds the recommended value in the servomotor list of specifications,
increase the motor capacity or change to a motor series with a large inertia. Note that the
recommended value for the load inertia ratio is strictly one guideline. This does not mean that
controlling a load with inertia exceeding the recommended value is impossible.

When selecting feed axis servomotors for NC unit machine tools, place
importance on the surface precision during machining. To do this, always
POINT select a servomotor with a load inertia ratio within the recommended value.
Select the lowest value possible within that range.

11-3-2 Short time characteristics

In addition to the rated output, the servomotor has an output range that can only be used for short
times such as acceleration/deceleration. This range is expressed at the maximum torque. The
maximum torque differs for each motor even at the same capacity, so confirm the torque in section
"10-2 Servomotor".
The maximum torque affects the acceleration/deceleration time constant that can be driven. The linear
acceleration/deceleration time constant ta can be approximated from the machine specifications using
expression (11-2). Determine the maximum motor torque required from this expression, and select the
motor capacity. The same selection can also be made by using the simple motor capacity selection
diagrams on the last pages of this section (11-3).

11-4 Selection of regenerative resistor

To select the regenerative resistor, first the regenerative energy from when each axis stops (is
positioned) is calculated. A regenerative resistor having a capacity to satisfy the positioning frequency,
determined from the machine specifications, is selected.

11-4-1 Calculation of regenerative energy

(1) For horizontal axis
For the horizontal axis, the regenerative energy ER consumed by the regenerative resistor can be
calculated with the expression (11-7). If the ER value is negative, all of the regenerative energy is
absorbed (CONDENSER REGENERATION) by the capacitor on the amplifier, and the energy
consumption by the regenerative resistor is zero (ER = 0).

η : Motor reverse effect
JL : Motor inertia (kg·cm2)
JM : Load inertia (kg·cm2)
N : Motor speed (r/min)
Ec : Amplifier charging energy (J)

Example
The regeneration energy is obtained for when the axis stops from the rated speed while a load with the
same inertia as the motor is connected to the HC52 motor.
Regeneration energy ER is calculated using expression (11-7) below.
ER = 5.48 × 10−7 × 0.85 × (6.6 + 6.6) × 20002 − 11 = 13.6 (J)

(2) For an unbalance axis

The regenerative energy differs in the upward stop and downward stop for an unbalance axis. A
constant regeneration state results during downward movement if the unbalance torque is the
same as or larger than the friction torque.

One return is assumed to be one cycle, and the regeneration energy per cycle (ER) is obtained using
expression (11-10).
ER = ERU + ERD (J) .................................................... (11-10)

(Example)

A return operation is executed for a time constant of 50msec for 200mm. The operation is executed at
F20000 in a machine tool vertical axis driven by an HC52 motor. The regenerative energy per return
operation is obtained at this time.
Note the following :
Travel per upward motor rotation : 10mm
Upward stop deceleration torque : 5N·m
Downward stop deceleration torque : 8N·m
Upward torque during downward movement : 0.5N·m
Using expression (11-8), the upward stop regeneration energy ERU is as follows :
ERU = 5.24 × 10−5 × 0.85 × 5 × 2000 × 50 − 11 = 11.3 (J)
The acceleration/deceleration distance required to accelerate at the 50msec acceleration/ deceleration
time constant to 20000mm/min. is as follows:
20000 × 50
= 8.3 (mm)
2 × 60 × 1000
Therefore, the constant speed travel is 183.4mm.
The downward stop regeneration energy ERD is obtained using the following expression (11-9).
2π × 0.85 × 0.5 × 183.4
ERD = + 5.24 × 10−5 × 0.85 × 8 × 2000 × 50 − 11 = 73.6 (J)

Thus, the regeneration energy per return operation ER is as follows :

ER = 11.3 + 73.6 = 84.9 (J)

Select the regenerative resistor so that the positioning frequency DP (times/minute) calculated by the
regenerative resistor capacity PR (W) and the regenerative energy ER (J) consumed by the
regenerative resistor is within the range shown in expression (11-11). With the unbalance axis, the
number of times for one cycle to raise and lower the axis is judged as DP.

side gear inertia.
The ball screw is generally calculated as a cylinder made of steel.

secondary side load inertia to the motor shaft (primary side), multiply by the square of the
deceleration ratio.

• Load inertia: JL
This is the sum of the total rotation load inertia and the linear movement inertia.
JL = 13.9 + 4.6 = 18.5 (kg·cm2)
When looking at the load inertia components, the linear movement weight tends to increase.
However, the rotation load generally accounts for most of the inertia. The load inertia does not
change much even if the workpiece weight changes greatly in the table axis.

(2) Obtaining unbalance torque

The unbalance torque is obtained from the moving object weight. Here, the drive system

(4) Selecting the appropriate motor from the load inertia ratio
Because it is a machine tool, the HC† Motor Series is required for precise control, and a motor
maximum speed of 3000r/min. or more is required because of the rapid traverse speed and gear
ratio. Furthermore, the motor to be selected is limited to the HC†3B Series because a motor with
brakes is required. The load inertia for all the HC53B to HC153B motors in the table below is
judged to be appropriate if the load inertia is within 5-fold of the recommended load inertia ratio.

(6) Selecting the appropriate motor from the continuous characteristics

Generally, the expressions (11-3) and (11-4) are calculated following the typical operation pattern,
and the motor is judged from the continuous characteristics. Because the Z axis is the vertical
axis here, the motor will be judged by the torque during an upward stop.
The unbalance axis torque during a stop is 60% or less of the stall torque (rated torque in
general-purpose motors). As shown in the following table, the only motor that satisfies this
reference is the HC153B. From the judgment in steps (4) to (6) it is the motor with the appropriate
Z axis.

11-5-2 Regenerative resistor selection calculation

Calculation is carried out in order with the Z axis as an example.
(1) Obtaining the generated torque
The deceleration torque required to calculate the regeneration energy is obtained.
• Upward stop deceleration torque: Tdu
The amount of deceleration torque (=amount of acceleration torque) is first calculated using
expression (11-5).
(JL + JM) × N (18.5 + 22.0) × 3000
Ta = = = 10.6 (N·m)
95.5 × ta 95.5 × 120
The upward stop deceleration torque is obtained from the amount of deceleration torque,
unbalance torque and friction torque.
Tdu = Ta − TU − TF = 10.6 − 4.3 − 0.09 = 6.2 (N·m)

• Downward stop deceleration torque: Tdd

The downward stop deceleration torque is obtained from the amount of deceleration torque,
unbalance torque and friction torque.
Tdd = Ta − TU − TF = 10.6 − 4.3 − 0.09 = 14.8 (N·m)

• Upward torque during dropping: Ts

The upward torque during dropping is obtained from the unbalance torque and friction torque.
Ts = TU − TF = 4.3 − 0.09 = 4.2 (N·m)

• Constant rate travel: L

Because the constant rate travel is not clearly described in the specifications, the axis stroke, etc.,
is considered, and the value used here is L=200mm.

(2) Obtaining the regeneration energy

Because the Z axis is the vertical axis, the regenerative energy is calculated separately for an
upward stop and downward stop.
• Upward stop regeneration energy: ERU
This is obtained from expression (11-8).
ERU = 5.24 × 10−5 · η · Tdu · N · td − Ec = 5.24 × 10−5 × 0.85 × 6.2 × 3000 × 120 − 40 = 59.4 (J)

• Downward stop regeneration energy: ERU

This is obtained from expression (11-9).
2π · η · Ts · L
ERD = + 5.24 × 10−5 · η · Tdd · N · td − Ec
ΔS
2π × 0.85 × 4.2 × 200 × 3
= + 5.24 × 10−5 × 0.85 × 14.8 × 3000 × 120 − 40
10 × 2
= 672.9 + 237.3 − 40 = 870.2 (J)
• Stop regeneration energy per cycle: ER
This is obtained from expression (11-10).
ER = 59.4 + 870.2 = 929.6 (J)
11-17
 Chapter 11 Selection

(3) Obtaining the tolerable No. of positionings

The tolerable cycle operation frequency per minute DP is calculated respectively for the standard
built-in regeneration resistor and option regeneration resistor.
Refer to expression (11-11).
• Standard built-in regenerative resistor
PR 100
DP0 = 48 · = 48 × = 5.2 (times) No. of positionings = 10.4 (times)
ER 929.6

• MR-RB30 (300W)
PR 300
DP1 = 48 · = 48 × = 15.5 (times) No. of positionings = 31.0 (times)
ER 929.6

• MR-RB50 (500W)
PR 500
DP2 = 48 · = 48 × = 25.8 (times) No. of positionings = 51.6 (times)
ER 929.6

Because the No. of times described above is the No. of cycle operations for 1 return for a vertical
axis, the No. of positionings is 2-fold. Thus, it is shown that the MR-RB30 (300W) option resistor
is required to satisfy the specified positioning frequency of 20 times/min.

Try to choose a resistor with some allowance in the vertical axis, because the
POINT regeneration load can easily become large compared to a horizontal axis.

 Chapter 12 Inspections

1. Wait at least 10 minutes after turning the power OFF and check that the
input/output and voltage are zero with a tester, etc., before starting wiring or
inspections. Failure to observe this could lead to electric shocks.
DANGER 2. Only qualified persons must carry out the inspections. Failure to observe
this could lead to electric shocks. Contact your dealer for repairs or part
replacements.

１．Do not perform a megger test (insulation resistance measurement) on the

CAUTION servo amplifier. Failure to observe this could lead to faults.
２．Never disassemble or modify the unit.

12-1 Inspections
Periodically inspecting the following points is recommended.
① Are any screws on the terminal block loose? Tighten if loose.
② Is there any abnormal noise from the servomotor bearings or the brakes?
③ Are any of the cables damaged or cracked? If the cable moves with the machine, carry out a
periodic inspection according to the usage conditions.
④ Is the axis at the load coupling section misaligned?

12-2 Life parts

The guidelines for the part replacement interval are as shown below. These will differ according to the
usage methods and environmental conditions, of if an abnormality is found, the part must be replaced.
Contact your dealer for repairs and part replacements.

Part name Standard replacement time Remarks

Servo amplifier Smoothing capacity 10 years The standard replacement time is a
Relay – reference time. If an abnormality is
found before the standard
Cooling fan 10,000 to 30,000 hours
replacement time is reached, the part
(2 to 3 years) must be replaced.
Battery 10,000 hours
Servomotor Bearings 20,000 to 30,000 hours
Detector 20,000 to 30,000 hours
Oil seal, V-ring 5,000 hours

①Smoothing capacitor : The smoothing capacitor characteristics will deteriorate due to the effect
of the ripple current, etc. The capacitor life will be greatly affected by the
ambient temperature and usage conditions, but when run continuously in
a normal air-conditioned environment, the life will be reached in 10 years.
②Relays : Contact defects will occur due to contact wear caused by the switching
current. This will differ according to the power capacity, but the life will be
reached at a No. of cumulative switches (switching life) of 100,000 times.
③ Servomotor bearings : When used at the rated speed and rated load, replace the bearings after
about 20,000 to 30,000 hours. This will differ according to the operation
state, but if abnormal noise or vibration is found during the inspection, the
bearings must be replaced.
④ Servomotor oil seal, V-ring: These parts must be replaced after about 5,000 hours of operation at the
rated speed. This will differ according to the operation state, but these
parts must be replaced if oil leaks, etc., are found during the inspection.
