Rev.09 v. 09-2023 pag. 4

2) Safety
2.1 Safety notes

The person carrying out instandstillation is required to perform risk assessment for the machine and to take appropriate
measures to ensure that unforeseen movements will not cause injury or damage to persons or property.

Make sure that the motor housing is adequately earthed to the reference earth busbar. No electrical safety can be guaranteed for
persons without a low-resistance earth connection.

Do not unplug any of the connectors during operation. This creates a danger of death, severe injury, or extensive material damage.

Power connections may be live even when the motor is not turning. Never unfasten the motor power connections while the
equipment is under power. In unfavourable situations this can cause flashovers, with resulting injuries to persons and damage to
property.

After disconnecting the servomotors from the supply voltage, wait several minutes before touching any components which are
normally live (e.g: contacts, screw connections) or opening any connections. To be quite safe, measure the voltage in the
intermediate circuit and wait until the voltage has fallen below 40V.

The surfaces of the motors can be very hot during operation, according to their protection category. The surface
temperature can exceed 100°C. Measure the temperature, and wait until the motor has cooled down to below 40°C
before touching it.

Remove any key (if present) from the shaft or fasten it if the motor is running independently, to avoid the danger of injury due to
the key being thrown out by centrifugal force.

Built-in holding brakes do not guarantee the safety of personnel! Hanging loads (vertical axes) require an additional, external
mechanical brake to guarantee the safety of personnel.

Repairs must only be carried out by the manufacturer or by authorised repair workshops. Unauthorised opening and poorly
performed repairs may result in injury or material damage, and will invalidate the warranty.

Before starting up motors that have a tongue at the end of the shaft, this element must be fastened to ensure it does not come
out, if this cannot be prevented by drive elements such as pulleys, joints or the like.

Only properly qualified personnel are permitted to perform such tasks as transport,
assembly, setup and maintenance. Properly qualified personnel are persons who are familiar with the transport, assembly,
instandstillation, setup and operation of motors, and who have the appropriate qualifications for their jobs. Qualified personnel must know and
observe the following standards and regulations: IEC 60364 or IEC 60664, National safety/accident prevention regulations.

Always use suitable lifting equipment to lift and move motors weighing more than 20 Kg. Lifting the motors without assistance
could result in back injury.

Read this documentation before assembly and setup. Incorrect handling of the motor can result in injury and damage to persons
and property. Always comply with the technical data and the information on connection requirements (rating plate and
documentation).

The motors are not designed to be connected directly to the three phase power supply, but must be operated using an electronic
frequency converter. Direct connection to the mains can cause damage to the motor.

The thermal probe integrated in the winding to protect the motor from slow thermal overloading must be connected and checked
by means of a suitable command.

In motors fitted with a brake, check for the presence of a varistor on the brake power circuit before starting up.

8.4 Insulation class

The motors comply with insulation class F according to IEC 60034-1.

8.5 Surface
The motors are coated with high adhesion RAL9005 matt black coating for light alloys. This finish is not resistant against solvents.

Rev.09 v. 09-2023 pag. 49

8.6 Shaft end, A-side
Power transmission is through the cylindrical shaft end A, with dimensions according to IEC 60072-1. Bearing life has been
calculated based on 20,000 working hours at the radial and axial force values indicated.

Radial force
If the motors drive via pinions or toothed belts, then high radial forces will occur. The permissible values at the end of the shaft
can be found in the technical specifications, according to the rated speed.

Axial force
Axial forces arise when assembling pinions or wheels to the axis and when using angular gearheads as drive elements.
The permissible values can be found in the technical specifications, according to the rated speed.

8.7 Thermal protection device

The standard version of each motor is fitted with a PTC device. The switching point is 130°C ± 5%. This PTC does not provide any
protection against short term, heavy overloading, particularly in the case of smaller motors.
Options: PT1000.

8.8 Vibration class

DSM5/DSF5/DSM7 motors are made to vibration class A according to EN 60034-14 with half key if present.
The vibration values indicated refer to the motor alone up to rated speed. Vibrations in the system due to installation may cause
an increase in this value for the motor.

Standard: vibration class A.

Optional: vibration class B.

8.9 Holding brake
The motors are available with an optional integrated holding brake. The permanent magnet type brake locks the rotor when no
voltage is applied.

The safety of personnel can only be guaranteed in the case of hanging loads (vertical axes) when an additional, external
mechanical brake is fitted. If the brake is released then the rotor can be moved without any resisting torque.

The brakes are designed as standstill or holding brakes and are not suitable for repeated operational or dynamic braking.
The motor length increases when a holding brake is fitted.

If the holding brake is not controlled directly by the servo amplifier, an additional component (for example a varistor) must be
wired.

8.10 Instandstillation and operating conditions

▪ The motors must be used according to the specifications provided in paragraph 5.1.

8.11 Cleaning plan

Recommended cleaning plan:

▪ Flush with water (40° ... 50°C).

Flush at low pressure, from top to bottom in the direction of the drain.
▪ Cleaning with alkaline detergents.
Use a clean cloth.
▪ Do not use solvents

Rev.09 v. 09-2023 pag. 51

9) Mechanical installation

The dimensions of the motors can be found in the preceding paragraphs.

9.1 Important notes

Only qualified staff with knowledge of mechanical engineering are permitted to instandstill the motor.
Protect the motor from unacceptable stress. Take care, particularly during transport and handling, that components are not bent
and that insulation distances are not altered.
The instandstillation site must be free of conductive and aggressive materials. For V3 mounting (shaft end upwards), make sure
that no liquids can enter the bearings.

Ensure free ventilation of the motors and observe the permissible ambient and flange temperatures. For ambient temperatures
above 40°C please contact our technical department to request derating. Ensure that there is adequate heat transfer in the
surroundings and the motor flange, so that the maximum permissible flange temperature is not exceeded in S1 operation.

Servomotors are precision equipment. The flange and shaft are especially vulnerable during storage and assembly - so avoid using
brute force. Use the locking thread provided for the drive shaft (see figure) to fasten drive components such as gear wheels or
pulley wheels, and warm up the drive components whenever possible. Striking blows or the use of force will lead to damage to the
bearings and the shaft.

If the brake is present, no axial loads must be used, to prevent modification of the brake settings.

Fitting Removing

Make sure that the coupling is correctly aligned.

Any displacement will cause unacceptable vibration and may result in destruction of the bearings and the coupling itself.
When used with toothed belts or pulleys, observe the permissible radial forces.
An excessive axial load on the shaft will significantly shorten the life of the motor.
Whenever possible, avoid axial stress on the drive shaft. Axial load on the shaft will significantly shorten the life of the motor.
Take note of the number of motor poles and the number of resolver poles, and ensure that the correct number of poles is used
when setting up the servo amplifier.
An incorrect setting can lead to irreparable damage, particularly in the case of smaller motors.
Check compliance with the permitted radial and axial forces FR and FA.

Rev.09 v. 09-2023 pag. 52

10) Electrical installation

Wiring diagrams can be found in the instruction manual for the servo amplifiers.

10.1 Safety notes

Only qualified staff with training in electrical engineering are permitted to wire the motor.
Always make sure that the motors are de-energised during assembly and wiring, i.e. no voltage must be switched on in the
equipment to be connected. Make sure that the electrical cabinet has been safely turned off (barrier, warning signs, etc.). The
individual voltages will only be turned on again during setup.
Never unfasten the motor power connections while the equipment is under power. Dangerous voltages may still be present in the
servo amplifier capacitors several minutes after the mains power supply has been switched off. Measure the voltage in the
intermediate circuit and wait until the voltage has fallen below 40V. Control and power connections may be live even when the
motor is not turning.

The ground symbol which you will find in the wiring diagrams, indicates that you must provide an electrical connection with
as large a surface area as possible between the unit indicated and the mounting plate in the electrical cabinet. This connection is
to allow dispersion of high frequency interference, and must not be confused with the PE (protective earth) symbol (protective
measure according to EN 60204). Also follow the notes in the instruction manual wiring diagrams for the servo amplifier used,
which requires periodic verification of the state of the grounding system.

10.2 Guide for electrical instandstillation

▪ Check that the servo amplifier and the motor match each other. Compare the rated voltage and rated current in the units.
Carry out the wiring according to the wiring diagram in the servo amplifier instruction manual. The motor connections
are indicated in the preceding chapters.
▪ Check that the feedback instandstilled on the motor is of a suitable type and in line with the drive manufacturer's
requirements. In case of doubt, perform laboratory tests.
▪ Ensure that earthing of the servo amplifier and motor is carried out properly. Make sure that shielding and earthing
comply with electromagnetic compatibility requirements. Earth the mounting plate and motor casing.
▪ If possible, route the power and signal cables separately (separation >20cm). This will improve the immunity of the system
to electromagnetic interference. If a motor power cable is used which includes integral brake control leads, then these
brake control leads must be shielded. The shielding must be connected at both ends (see the servo amplifier
instandstillation manual).
▪ Cabling
- If possible, route the power and control cables separately.
- Connect up the resolver or encoder
- Connect the motor cables, first to the motor choke (if there is one) then to the servo amplifier.
- Ground the shielding cables at both ends.
- Connect the motor holding brake, if there is one.
▪ All the cables carrying heavy currents must have an adequate cross-section, as per EN60204-1:2006.
▪ Connect up all shielding via a wide surface-area contact (low impedance) and metallised connector housings or EMC-
compatible threaded cable gland.
▪ Check the quality of earthing periodically.

10.3 Electrical Connection of the motors

▪ Carry out the wiring in accordance with the standards and regulations in force.
▪ Only use suitable tested shielded cables for the resolver and power connections.
▪ Connect up the shielding according to the wiring diagrams in the servo amplifier instruction manuals.
▪ Incorrectly instandstilled shielding inevitably causes electromagnetic disturbance.
▪ Maximum cable length: follow the indications given in the servo amplifier instruction manuals.

Please contact the technical department when selecting the cables.

Rev.09 v. 09-2023 pag. 53
11) Setup

11.1 Important notes

Only specialist personnel with extensive technical knowledge are allowed to commission the drive unit with servo amplifier/motor.
Check that all live connection points are safe against accidental contact. Deadly voltages of up to 900V can occur.
Never unfasten the motor power connections while the equipment is under power. Dangerous voltages may still be present in the
servo amplifier capacitors several minutes after the mains power supply has been switched off.
The surface temperature of the motor can exceed 100°C in operation. Check (measure) the temperature of the motor. Wait until
the motor has cooled down to 40°C before touching it.
Make sure that, even if the rive starts to move unintentionally, no danger can result for personnel or machinery.

11.2 Guide for setup

The setup procedure is described as an example. A different method may be appropriate or necessary, depending on the expected
use.
▪ Check the assembly and orientation of the motor.
▪ Check that the drive components are in their proper housings and have been set correctly (respecting the permissible
radial and axial forces).
▪ Check the wiring and connections to the motor and the servo amplifier. Ensure that earthing has been carried out
properly.
▪ Check that the holding brake, if there is one, is working properly (the brake must release when 24V is applied).
▪ Check whether the motor rotor can turn freely (first release the brake, if there is one). Listen for grinding noises.
▪ Check that the required measures against accidental contact with live and moving parts have been taken.
▪ Carry out any further tests which are specifically required for your system.
▪ Commission the drive according to the setup instructions for the servo amplifier.
▪ In multi-axis systems, individually commission each servo amplifier/motor drive unit at minimum performance levels.
▪ Only perform complete testing after you have ensured that all components and settings are suitable.

11.3 Troubleshooting

The following table is to be seen as a "First Aid" box. There may be a number of possible reasons for a fault, depending on the
conditions in the system you are using. The fault causes described below are mostly those relating directly to the motor. Errors in
parametrisation of the servo amplifier will cause malfunctions and possibly faults. Please consult the documentation for the servo
amplifier and the operating software, and check that the tutor feedback is compatible with the drive requirements.
In interpolating systems the CNC may also be involved in any causes of malfunction.
Our technical department is able to provide any support required.

All data is defined for the following conditions: max. environmental temperature 40°C and 100K over temperature of the winding.
Maximum altitude 1000 m asl
The values have a maximum tolerance of ± 10%.

12.1 Definitions

Standstill torque at 20°C M0 [Nm]

The standstill or standstill torque is delivered by the cold motor (20°C) at a speed of 0<n<100 rpm. It does not take into account
any torque dissipation (due to iron, mechanical, saturation, wave deformity). With the same current, the stall torque decreases
as the motor temperature increases.
(see Motor heating characteristic curves for values with hot motor)

Standstill current I0 [A]

Current (rms value) applicable to the motor at a number of revolutions 0 <n <100 rpm. By applying this current to the cold engine
(20 ° C), M0 is delivered, the increase in overtemperature leads to a decrease in the torque with the same current I 0
(see Motor heating characteristic curves for values with hot motor)

Maximum mechanical revs Nmec [min-1]

The maximum mechanical revs indicate the maximum operating speed that is permitted at mechanical level.

Rotor moment of inertia Jr [kgcm²]

The inertia of the rotor without taking into consideration the transducer and the brake. (Kg cm2=kg*m2 *10-4).

Maximum torque Mpk [Nm]

Torque that is generated when the peak load is applied.
The maximum torque is only available for short periods of time.

Maximum revs Nmax [min-1]

After defininig a specific BUS voltage, maximum reachable speed at which the maximum deliverable torque is guaranteed to be 2
* Mo. In the event that 2 * Mo is greater than the maximum torque value indicated on the motor specifications, the maximum
speed refers to the knee of the Mpk / rpm curve.
It is not possible to sustain S1 service at maximum revs.

Peak current (pulse current) Ipk [A]

The peak current (rms value is up to 5 times the rated standstill current. The peak current of the servo amplifier used must be
lower than the peak value of the motor.

Voltage constant KE [mVmin]

Effective line to line voltage value at a speed of 1000rpm. The Ke is defined when operating without load (circuit open and motor
driven) at a temperature of 20°C. The progress of the line to line voltage in these conditions is in linear proportion to the
mechanical speed.

Torque constant KT [Nm/A]

The torque constant indicates the ratio between M 0 and I0 and does not take into account any dissipation.

Resistance Ru-v [ohm]
Resistance between two phases at 20°C.

Inductance Lu-v [mH]

Inductance between two phases measured at 1KHz.

Electric time constant τe [msec]

The constant τe indicates the ratio between inductance and resistance.

Thermal time constant τ1 [min]

The constant τ1 indicates the warm-up time for the motor from cold with a load of I0 until it reaches an over temperature of 63
Kelvin. When under peak current load, warm-up takes place in a considerably shorter time.

Mechanical time constant τm [msec]

The constant τm is defined as follows:
𝟎, 𝟏𝟓 ∗ 𝐑𝐮−𝐯 ∗ 𝑱𝒓
𝛕𝐦 = [𝒎𝒔𝒆𝒄]
𝑲𝟐𝒕

Thermal capacity Cth [J/K]

The thermal capacity is the ratio between the heat exchanged with the environment and the variation in temperature that results
from it.

Thermal resistance Rth [K/W]

The thermal resistance is the ratio, in a stationary state, between the temperature gradient and the heat flow.

Radial shaft loading [Fr] and axial shaft loading [Fa]

The force Fr indicates the maximum radial force applicable at a distance L/2 from the end of the shaft, to guarantee an average
lifespan of 20,000 hours for the bearings.
The force Fa indicates the maximum axial force applicable to the end of the shaft, to guarantee an average lifespan of 20,000
hours for the bearings.

No axial force is permissible for motors with brake.

The information provided in this manual has been checked carefully, but may be subject to errors or modifications to adapt to the needs of the
manufacturer or technical improvements.
