 1.6 Storage Guidelines

1.6 Storage Guidelines

The chemicals in the electrolytic capacitors and other electronic parts of the drive change over time. When you store
the drive for long periods of time, use the information in this section to help keep the performance life estimates.

◆ Storage Location
• Temperature and Humidity
When you store the drive for approximately one month, for example during shipping, you can put the drive in a
location where the temperature is -20 °C to +70 °C (-4 °F to +158 °F). Correctly package and store the drive during
shipping to prevent vibration and impact damage.
Do not put the drive in direct sunlight or where there will be condensation or ice. Put the drive in a location where
the relative humidity is 95% or less.
• Dust and Oil Mist
Do not keep the drive locations with dust or oil mist. For example, cement factories and cotton mills.
• Corrosive Gas
Do not keep the drive in locations with corrosive gas. For example, chemical plants, refineries, and sewage plants.
• Salt Damage
Do not keep the drive in salty locations. For example, locations near the ocean, and salt damage-designated
locations.
Do not keep the drive in unsatisfactory locations. Keep all drives in storage rooms that are safe from unsatisfactory
elements.

◆ Regular Application of Power

To prevent deterioration of the capacitors, Yaskawa recommends that you apply power to the drive a minimum of one
time each year for a minimum of 30 minutes.
If you store the drive for longer than two years and do not apply power, Yaskawa recommends that you use a variable
power source and gradually increase the power from 0 V to the rated drive voltage over a period of 2 to 3 minutes.
Apply power for a minimum of 1 hour with no load to reform the main circuit electrolytic capacitor. When you
operate the drive after you apply power, wire the drive correctly and check for drive faults, overcurrents, motor
vibration, motor speed differences, and other defects during operation.

2.1 Section Safety

DANGER
Electrical Shock Hazard
Do not examine, connect, or disconnect wiring on an energized drive. Before servicing, disconnect
all power to the equipment and wait for the time specified on the warning label at a minimum. The
internal capacitor stays charged after the drive is de-energized. The charge indicator LED
extinguishes when the DC bus voltage decreases below 50 Vdc. When all indicators are OFF,
remove the covers before measuring for dangerous voltages to make sure that the drive is safe.
If you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.

WARNING
Electrical Shock Hazard
Do not operate the drive when covers are missing. Replace covers and shields before you operate
the drive. Use the drive only as specified by the instructions.
Some figures in this section include drives without covers or safety shields to more clearly show the inside of the
drive. If covers or safety shields are missing from the drive, it can cause serious injury or death.
Always ground the motor-side grounding terminal.
If you do not ground the equipment correctly, it can cause serious injury or death if you touch the motor case.
After the drive blows a fuse or trips a GFCI, do not immediately energize the drive or operate
peripheral devices. Wait for the time specified on the warning label at a minimum and make sure
that all indicators are OFF. Then check the wiring and peripheral device ratings to find the cause of
the problem. If you do not know the cause of the problem, contact Yaskawa before you energize the
drive or peripheral devices.
If you do not fix the problem before you operate the drive or peripheral devices, it can cause serious injury or death.
Only let approved personnel install, wire, maintain, examine, replace parts, and repair the drive.
If personnel are not approved, it can cause serious injury or death.
Do not wear loose clothing or jewelry when you do work on the drive. Tighten loose clothing and
remove all metal objects, for example watches or rings.
Loose clothing can catch on the drive and jewelry can conduct electricity and cause serious injury or death.
Do not remove covers or touch circuit boards while the drive is energized.
If you touch the internal components of an energized drive, it can cause serious injury or death.
Do not modify the drive body or drive circuitry.
Modifications to drive body and circuitry can cause serious injury or death, will cause damage to the drive, and will
void the warranty. Yaskawa is not responsible for modifications of the product made by the user.
Fire Hazard
Tighten all terminal screws to the correct tightening torque.
Connections that are too loose or too tight can cause incorrect operation and damage to the drive. Incorrect
connections can also cause death or serious injury from fire.
Tighten screws at an angle in the specified range shown in this manual.
If you tighten the screws at an angle not in the specified range, you can have loose connections that can cause
damage to the terminal block or start a fire and cause serious injury or death.
Damage to Equipment
Do not apply incorrect voltage to the main circuit of the drive. Operate the drive in the specified
range of the input voltage on the drive nameplate.
Voltages that are higher than the permitted nameplate tolerance can cause damage to the drive.

2.7 Auto-Tuning Errors

This table gives information about errors detected during Auto-Tuning. If the drive detects an Auto-Tuning error, the
keypad will show the error and the motor will coast to stop. The drive will not send notification signals for faults and
alarms when Auto-Tuning errors occur.
Two types of Auto-Tuning errors are: Endx and Erx. Endx identifies that Auto-Tuning has successfully completed
with calculation errors. Find and repair the cause of the error and do Auto-Tuning again, or set the motor parameters
manually. You can use the drive in the application if you cannot find the cause of the Endx error.
Erx identifies that Auto-Tuning was not successful. Find and repair the cause of the error and do Auto-Tuning again.

• Set A1-02 = 0 [Control Method Selection = V/f Control].

The voltage insulation between motor phases is not sufficient. • Use a motor with a voltage tolerance that is higher than the maximum voltage surge.
• Use a drive-dedicated motor that is rated for use with AC drives for applications that use a motor
on drives rated higher than 480 V class.
• Install an AC reactor on the output side of the drive and set C6-02 = 1 [Carrier Frequency
Selection = 2.0 kHz].
Note:
When the motor is connected to the drive output terminals U/T1, V/T2, and W/T3, surges occur
between the drive switching and the motor coils. These surges can be three times the drive input
power supply voltage (600 V for a 208 V class drive, 1200 V for a 480 V class drive).

The air around the motor is too hot. • Measure the ambient temperature.
• Decrease the temperature in the area until it is in the specified temperature range.

The motor fan stopped or is clogged. • Clean the motor fan.

• Make the drive environment better.

◆ oPE02 Error Occurs When Decreasing the Motor Rated Current Setting
Causes Possible Solutions

Motor rated current and the motor no-load current setting in the drive are • You are trying to set the motor rated current in E2-01 [Motor Rated Current (FLA)] to a value
incorrect. lower than the no-load current set in E2-03 [Motor No-Load Current].
• Make sure that value set in E2-01 is higher than E2-03.
• If it is necessary to set E2-01 lower than E2-03, first decrease the value set to E2-03, then change
the E2-01 setting as necessary.

◆ The Correct Auto-Tuning Mode Is Not Available

Causes Possible Solutions

The desired Auto-Tuning mode is not available for the selected control mode. Change the motor control method with parameter A1-02 [Control Method Selection].

◆ The Motor Stalls during Acceleration or Accel/Decel Time Is Too Long

Causes Possible Solutions

The drive and motor system reached the torque limit or current suppression will • Decrease the load.
not let the drive accelerate. • Use a larger motor.
Note:
Although the drive has a Stall Prevention function and a Torque Compensation Limit function,
accelerating too fast or trying to drive a load that is too large can exceed the limits of the motor.

Torque limit is set incorrectly. Set the torque limit correctly.

The acceleration time setting is too short. Examine the values set in C1-01 or C1-03 [Acceleration Times] and set them to applicable values.

The load is too heavy. • Increase the acceleration time.

• Examine the mechanical brake and make sure that it is fully releasing.
• Decrease the load to make sure that the output current stays less than the motor rated current.
• Use a larger motor.
Note:
• In extruder and mixer applications, the load can increase as the temperature decreases.
• Although the drive has a Stall Prevention function and a Torque Compensation Limit function,
accelerating too fast or trying to drive a load that is too large can exceed the limits of the motor.

The frequency reference is low. • Examine E1-04 [Maximum Output Frequency] and increase the setting if it is set too low.
• Examine U1-01 [Frequency Reference] for the correct frequency reference.
• Examine the multi-function input terminals to see if a frequency reference signal switch has been
set.
• Examine the low gain level set in H3-03, H3-11 [Terminal A1, A2 Gain Setting] when you use
MFAI.

The frequency reference is set incorrectly. When H3-02, H3-10 = 1 [MFAI Function Selection = Frequency Gain] are set, see if voltage
(current) has been set.
• Check the values set in H3-02 and H3-10.
• Use U1-13 and U1-14 [Terminal A1, A2 Input Voltage] to make sure that the analog input values
set to terminals A1 and A2 are applicable.

The motor characteristics and drive parameter settings are not compatible. • Set the correct V/f pattern to agree with the characteristics of the motor.
• Examine the V/f pattern set in E1-03 [V/f Pattern Selection].
• Perform Rotational Auto-Tuning.

Troubleshooting

completed. • Calculate motor data and reset motor parameters.
• Set A1-02 = 0 [Control Method Selection = V/f Control].

The Stall Prevention level during acceleration setting is too low. Increase the value set in L3-02 [Stall Prevent Level during Accel].
Note:
If the L3-02 value is too low, the acceleration time can be unsatisfactorily long. 2
The Stall Prevention level during run setting is too low. Increase the value set in L3-06 [Stall Prevent Level during Run].
Note:
If the L3-06 value is too low, speed will decrease while the drive outputs torque.

Drive reached the limitations of the V/f motor control method. • When the motor cable is longer than 50 m (164 ft), do Auto-Tuning for line-to-line resistance.
• Set the V/f pattern to “High Starting Torque”.
• Use a Vector Control method.
Note:
V/f control method does not provide high torque at low speeds.

PID control is enabled. If PID control is not necessary, set b5-01 = 0 [PID Mode Setting = Disabled].
Note:
When PID control is enabled, the drive adjusts the output frequency as specified by the target
value. The drive will only accelerate to the maximum output frequency set in E1-04 [Maximum
Output Frequency] while PID control is active.

◆ The Motor Speed Is Not Stable When Using a PM Motor

Causes Possible Solutions

Parameter E5-01 [PM Motor Code Selection] is set incorrectly. Refer to “Motor Performance Fine-Tuning” in the technical manual.

The drive is operating the motor at more than the specified speed control range. Examine the speed control range and adjust the speed.

The motor is hunting. Adjust these parameters to have the largest effect:
• n8-55 [Motor to Load Inertia Ratio]
• n8-45 [Speed Feedback Detection Gain]
• C4-02 [Torque Compensation Delay Time]

Hunting occurs at start. Increase the value set in C2-01 [S-Curve Time @ Start of Accel].

Too much current is flowing through the drive. Set E5-01 correctly as specified by the motor. For special-purpose motors, enter the correct value to
E5-xx as specified by the motor test report.

◆ There Is Too Much Motor Oscillation and the Rotation Is Irregular

Causes Possible Solutions

Unsatisfactory balance of motor phases. • Make sure that the drive input power voltage supplies stable power.
• Set L8-05 = 0 [Input Phase Loss Protect Select = Disabled].

The motor is hunting. Set n1-01 = 1 [Hunting Prevention Selection = Enabled].

◆ There Is Audible Noise from the Drive or Motor Cables When the Drive Is
Energized
Causes Possible Solutions

The relay switching in the drive is making too much noise. • Use C6-02 [Carrier Frequency Selection] to decrease the carrier frequency.
• Connect a noise filter to the input side of the drive power supply.
• Connect a noise filter to the output side of the drive.
• Isolate the control circuit wiring from the main circuit wiring.
• Use a metal cable gland to wire the drive.
• Shield the periphery of the drive with metal.
• Make sure that the drive and motor are grounded correctly.
• Make sure that ground faults have not occurred in the wiring or motor.

◆ The Ground Fault Circuit Interrupter (GFCI) Trips During Run

Causes Possible Solutions

There is too much leakage current from the drive. • Increase the GFCI sensitivity or use GFCI with a higher threshold.
• Use C6-02 [Carrier Frequency Selection] to decrease the carrier frequency.
• Decrease the length of the cable used between the drive and the motor.
• Install a noise filter or AC reactor on the output side of the drive. Set C6-02 = 1 [2.0 kHz] when
connecting an AC reactor.
• Disable the internal EMC filter.

◆ Motor Rotation Causes Unexpected Audible Noise from Connected Machinery

Causes Possible Solutions

Note:
If C6-02 = 7 to A [Carrier Frequency Selection = Swing PWM], the drive will not know if the
noise comes from the drive or the machine.

The drive output frequency and the resonant frequency of the connected • Adjust d3-01 to d3-04 [Jump Frequency].

interference in the signal. • Isolate control circuit wiring from main circuit wiring.
• Use twisted-pair cables or shielded wiring for the control circuit.
• Increase the value of H3-13 [Analog Input FilterTime Constant].

The cable between the drive and motor is too long. • Do Auto-Tuning.
• Make the wiring as short as possible.

The PID parameters are not sufficiently adjusted. Adjust b5-xx [PID control].

◆ PID Output Fault

Causes Possible Solutions

There is no PID feedback input. • Examine the MFAI terminal settings.

• See if H3-02, H3-10 = B [MFAI Function Selection = PID Feedback] is set.
• Make sure that the MFAI terminal settings agree with the signal inputs.
• Examine the connection of the feedback signal.
• Make sure that b5-xx [PID Control] is set correctly.
Note:
If there is no PID feedback input to the terminal, the detected value is 0, which causes a PID
fault and also causes the drive to operate at maximum frequency.

Troubleshooting
The detection level and the target value do not agree. Use H3-03, H3-11 [Terminal A1, A2 Gain Setting] to adjust PID target and feedback signal scaling.
Note:
PID control keeps the difference between the target value and detection value at 0. Set the input
level for the values relative to each other.

Reverse drive output frequency and speed detection. When output frequency Set b5-09 = 1 [PID Output Level Selection = Reverse Output (Reverse Acting)].
increases, the sensor detects a speed decrease.

◆ The Starting Torque Is Not Sufficient
Causes Possible Solutions

Auto-Tuning has not been done in vector control method. Do Auto-Tuning.

The control method was changed after doing Auto-Tuning. Do Auto-Tuning again.

Stationary Auto-Tuning for Line-to-Line Resistance was done. Do Rotational Auto-Tuning.

◆ The Motor Rotates after the Drive Output Is Shut Off

Causes Possible Solutions

DC Injection Braking is too low and the drive cannot decelerate correctly. • Increase the value set in b2-02 [DC Injection Braking Current].
• Increase the value set in b2-04 [DC Inject Braking Time at Stop].

The stopping method makes the drive coast to stop. Set b1-03 = 0 or 2 [Stopping Method Selection = Ramp to Stop, DC Injection Braking to Stop].

◆ The Output Frequency Is Lower Than the Frequency Reference

Causes Possible Solutions

The frequency reference is in the Jump frequency range. Adjust d3-01 to d3-03 [Jump Frequency 1 to 3] and d3-04 [Jump Frequency Width].
Note:
Enabling the Jump frequency prevents the drive from outputting the frequencies specified in the
Jump range.

The upper limit for the frequency reference has been exceeded. Set E1-04 [Maximum Output Frequency] and d2-01 [Frequency Reference Upper Limit] to the best
values for the application.
Note:
This calculation supplies the upper value for the output frequency:
E1-04 × d2-01 / 100

A large load triggered Stall Prevention function during acceleration. • Decrease the load.
• Adjust L3-02 [Stall Prevent Level during Accel].

L3-01 = 3 [Stall Prevention during Accel = Current Limit Method] has been 1. Make sure that the V/f pattern and motor parameter settings are appropriate, and set them

high-capacity drive.

◆ The Motor Will Not Restart after a Loss of Power

Causes Possible Solutions

The drive did not receive a Run command after applying power. • Examine the sequence and wiring that enters the Run command.
• Set up a relay to make sure that the Run command stays enabled during a loss of power.

4.1 Section Safety

4.1 Section Safety

DANGER
Electrical Shock Hazard
Do not examine, connect, or disconnect wiring on an energized drive. Before servicing, disconnect
all power to the equipment and wait for the time specified on the warning label at a minimum. The
internal capacitor stays charged after the drive is de-energized. The charge indicator LED
extinguishes when the DC bus voltage decreases below 50 Vdc. When all indicators are OFF,
remove the covers before measuring for dangerous voltages to make sure that the drive is safe.
If you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.

WARNING
Electrical Shock Hazard
Do not operate the drive when covers are missing. Replace covers and shields before you operate
the drive. Use the drive only as specified by the instructions.
Some figures in this section include drives without covers or safety shields to more clearly show the inside of the
drive. If covers or safety shields are missing from the drive, it can cause serious injury or death.
Make sure that the protective ground wire complies with technical standards and local safety
regulations. The IEC/EN 61800-5-1:2007 standard specifies that you must wire the power supply to
automatically de-energize when the protective ground wire disconnects. You can also connect a
protective ground wire that has a minimum cross-sectional area of 10mm2 (copper wire) or 16 mm2
(aluminum wire). The leakage current of the drive will be more than 3.5 mA in drive models;
• 2xxxB
• 2xxxC
• 4002B to 4371B
• 4002C to 4371C (with built-in EMC filter turned ON)
• 4414 to 4720
• T414 to T720
If you do not obey the standards and regulations, it can cause serious injury or death.
When there is a DC component in the protective earthing conductor, the drive can cause a residual
current. When a residual current operated protective or monitoring device prevents direct or
indirect contact, always use a type B Ground Fault Circuit Interrupter (GFCI) as specified by IEC/EN
60755.
If you do not use the correct GFCI, it can cause serious injury or death.
Do not wear loose clothing or jewelry when you do work on the drive. Tighten loose clothing and
remove all metal objects, for example watches or rings.
Loose clothing can catch on the drive and jewelry can conduct electricity and cause serious injury or death.
Do not remove covers or touch circuit boards while the drive is energized.
If you touch the internal components of an energized drive, it can cause serious injury or death.
Only let approved personnel install, wire, maintain, examine, replace parts, and repair the drive.
If personnel are not approved, it can cause serious injury or death.
Do not modify the drive body or drive circuitry.
Modifications to drive body and circuitry can cause serious injury or death, will cause damage to the drive, and will
void the warranty. Yaskawa is not responsible for modifications of the product made by the user.
Fire Hazard
Tighten all terminal screws to the correct tightening torque.
Connections that are too loose or too tight can cause incorrect operation and damage to the drive. Incorrect
connections can also cause death or serious injury from fire.

 4.1 Section Safety

WARNING
Tighten screws at an angle in the specified range shown in this manual.
If you tighten the screws at an angle not in the specified range, you can have loose connections that can cause
damage to the terminal block or start a fire and cause serious injury or death.
Damage to Equipment
Do not apply incorrect voltage to the main circuit of the drive. Operate the drive in the specified
range of the input voltage on the drive nameplate.
Voltages that are higher than the permitted nameplate tolerance can cause damage to the drive.
Fire Hazard
When you install a dynamic braking option, wire the components as specified by the wiring
diagrams.
Incorrect wiring can cause damage to braking components or serious injury or death.

NOTICE
Do not let unwanted objects, for example metal shavings or wire clippings, fall into the drive during
drive installation. Put a temporary cover over the drive during installation. Remove the temporary
cover before start-up.
Unwanted objects inside of the drive can cause damage to the drive.
Damage to Equipment
When you touch the drive and circuit boards, make sure that you observe correct electrostatic
discharge (ESD) procedures.
If you do not follow procedures, it can cause ESD damage to the drive circuitry.
Select a motor that is compatible with the load torque and speed range. When 100% continuous
torque is necessary at low speed, use an inverter-duty motor or vector-duty motor. When you use a
standard fan-cooled motor, decrease the motor torque in the low-speed range.
If you operate a standard fan-cooled motor at low speed and high torque, it will decrease the cooling effects and can
cause heat damage.
Obey the speed range specification of the motor as specified by the manufacturer. When you must
operate the motor outside of its specifications, contact the motor manufacturer.
If you continuously operate oil-lubricated motors outside of the manufacturer specifications, it can cause damage to
the motor bearings.
When the input voltage is 440 V or higher or the wiring distance is longer than 100 m (328 ft), make
sure that the motor insulation voltage is sufficient or use an inverter-duty motor or vector-duty
motor with reinforced insulation.
Motor winding and insulation failure can occur.

Mechanical & Electrical Installation

Before you connect a dynamic braking option to the drive, make sure that qualified personnel read
and obey the Braking Unit and Braking Resistor Unit Installation Manual (TOBPC72060001).
If you do not read and obey the manual or if personnel are not qualified, it can cause damage to the drive and braking
circuit.
Make sure that all connections are correct after you install the drive and connect peripheral
devices.
Incorrect connections can cause damage to the drive.

4.1 Section Safety

Note:
• Torque characteristics differ compared to operating the motor directly from line power. The user should have a full understanding of the
load torque characteristics for the application.
• The current rating of submersible motors is usually higher than the current rating of standard motors for a given motor power. Make sure
that the rated output current of the drive is equal to or more than the current rating of the motor. If the motor wire length is longer than 100
m (328 ft), select the correct wire gauge to adjust for a loss in voltage and prevent a loss of motor torque.
• Do not use unshielded wire for control wiring. Use shielded, twisted-pair wires and ground the shield to the ground terminal of the drive.
Unshielded wire can cause electrical interference and unsatisfactory system performance.

Note:
• Isolate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, -, +1) and other high-power wiring.
If the control circuit wires are adjacent to the main circuit wires, electrical interference can cause the drive or the devices around the drive to
malfunction.
• Isolate contact output terminals MA, MB, MC and M1-M6 from other control circuit wiring. If the output terminal wires are adjacent to
other control circuit wires, electrical interference can cause the drive or devices around the drive to malfunction.
• Use a UL Listed Class 2 Power Supply to connect external power to the control terminals. If the power supply for peripheral devices is
incorrect, it can cause a decrease in drive performance.
• Connect the shield of shielded cable to the applicable ground terminal. If the grounding is not correct, electrical interference can cause the
drive or devices around the drive to malfunction.
Correctly ground the drive terminals and complete main circuit wiring before you wire the control circuit. Remove the
keypad and front cover.
1. Refer to Figure 4.27 and wire the control circuit.
WARNING! Fire Hazard. Tighten all terminal screws to the correct tightening torque. Connections that are too loose or too
tight can cause incorrect operation and damage to the drive. Incorrect connections can also cause death or serious injury
from fire.
Note:
• Use shielded wires and shielded twisted-pair wires for the control circuit terminal wiring. If the grounding is not correct, electrical
interference can cause the drive or devices around it to malfunction.
• Do not use control circuit wiring that is longer than 50 m (164 ft) to supply the frequency reference with an analog signal from a
remote source. Wiring that is too long can cause unsatisfactory system performance.

 4.8 External Interlock

4.8 External Interlock

For applications that will have unwanted effects on the system if the drive stops, make an interlock between fault
relay output (MA, MB, MC) and the MFDO DriveReady signal.

◆ Drive Ready
When the drive is operating or is prepared to accept a Run command, the MFDO terminal to which Drive Ready [H2-
xx = 6] is set will enter the ON status.
In these conditions, Drive Ready is OFF and the drive ignores Run commands:
• The drive is de-energized
• During a fault
• There is problem with the control power supply
• There is a parameter setting error that will not let the drive run, although a Run command is entered
• An overvoltage or undervoltage fault occurs when the Run command is entered
• The drive is in Programming Mode.

◆ Interlock Circuit Example

Refer to Figure 4.36 for an example of how two drives that run one application use the Drive Ready and Fault output
signals to interlock with the controller.

◆ Precautions before Auto-Tuning

Examine the topics in this section before you start Auto-Tuning.

■ Prepare for Basic Auto-Tuning

• You must input data from the motor nameplate or motor test report to do Auto-Tuning. Make sure that this data is
available before Auto-Tuning the drive.
• For best performance, make sure that the drive input supply voltage is equal to or more than the motor rated
voltage.
Note:
Better performance is possible when you use a motor with a rated voltage that is less than the input supply voltage (by 20 V for 208 V class
models or by 40 V for 480 V class models). This is very important when operating the motor at more than 90% of base speed, where high
torque precision is necessary. If the input power supply is equal to the motor rated voltage, the drive output voltage will not be sufficient, and
performance will decrease.

• Push on the keypad to cancel Auto-Tuning.

• If a Safe Disable input signal is input to the drive during Auto-Tuning, Auto-Tuning measurements will not
complete successfully. If this occurs, cancel the Auto-Tuning, then do it again.
• Table 5.14 shows the status of input/output terminals during Auto-Tuning.

WARNING! Crush Hazard. Wire a sequence that will not let a multi-function output terminal open the holding brake during
Stationary Auto-Tuning. If the holding brake is open during Stationary Auto-Tuning, it can cause serious injury or death.
WARNING! Sudden Movement Hazard. Before you do Rotational Auto-Tuning, disconnect the load from the motor. The load can
move suddenly and cause serious injury or death.
WARNING! Injury to Personnel. Rotational Auto-Tuning rotates the motor at 50% or more of the motor rated frequency. Make sure
that there are no issues related to safety in the area around the drive and motor. Increased motor frequency can cause serious
injury or death.
WARNING! Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.

■ Precautions before Rotational Auto-Tuning

WARNING! Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.
• Before you do Rotational Auto-Tuning to prevent drive malfunction, uncouple the motor from the load. If you do
Rotational Auto-Tuning with the motor connected to a load that is more than 30% of the motor duty rating, the
drive will not correctly calculate the motor parameters and the motor can operate incorrectly.
• When the load is 30% or less of the motor duty rating, you can do Auto-Tuning with the motor connected to a load.
• Make sure that the motor magnetic brake is released.
• Make sure that external force from the machine will not cause the motor to rotate.

■ Precautions before Stationary Auto-Tuning

• Make sure that the motor magnetic brake is not open.
• Make sure that external force from the machine will not cause the motor to rotate.
WARNING! Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.

■ Precautions before Stationary Auto-Tuning for Line-to-Line Resistance and Stator

Resistance Auto-Tuning
In V/f control, when the motor cable is 50 meters (164 feet) or longer, do Stationary Auto-Tuning for Line-to-Line
Resistance.
WARNING! Electrical Shock Hazard. During Auto-Tuning, the motor will receive high voltage when the motor is stopped. Do not
touch the motor until Auto-Tuning is complete. If you touch a motor that is energized, it can cause serious injury or death.

6.6 Drive Derating

6.6 Drive Derating

You must derate the drive capacity to operate the drive above the rated temperature, altitude, and default carrier
frequency.

◆ Carrier Frequency Settings and Rated Current Values

Table 6.13 and Table 6.14 show how the drive rated output current changes when the C6-02 [Carrier Frequency
Selection] value changes. The output current value changes linearly as the carrier frequency changes. You can use the
values from the tables to calculate a frequency that is not shown.
Note:
The drive will apply derating for the rated output current value based on the carrier frequency only to the reference output current value of
the oL2 [Drive Overload]. The derated value for the 100% rated output current in parameters and monitors will not be the same as the rated
output current value shown in Model Specifications (208 V Class) on page 345 and Model Specifications (480 V Class) on page 346.
