If the assembly steps have not yet reached the installation of the rotor, please place the
rotor in a safe and proper place first.
Never take multiple motors at once.
Do not bring any magnetizable materials close to the shaft! If the tool must be magnetized,
please hold it firmly with both hands and slowly approach the shaft!
Warning
! Risk of Personal Injury or Damage to Property.
Do not disassemble the servo drive or motor.
Do not attempt to change wiring while the power is ON.
When replacing the servo drive or motor, resume operation only after transferring the
previous servo system parameters to the new servo system.
Warning
! Risk of Personal Injury.
Lifting heavy loads may damage your health.
Use a hoist of an appropriate size when positioning heavy loads which are over 20 kg!
Observe applicable occupational health and safety regulations when handling suspended
loads!
Attention!
Risk of Physical Damage to Watches and Magnetic Storage Media.
Strong magnetic forces may destroy watches and magnetisable data storage media near to
the servo motor system!
Do not bring watches or magnetisable data storage media into the vicinity (<300 mm) of
the servo motor systems!
Warning
! Risk of Personal Injury or Damage to Property.
Obstacle removal and maintenance can only be performed by HIWIN technicians or
authorized dealers, and with appropriate protective equipment.
Do not perform any maintenance actions while the motor is running. The controller must
stop the motor first.
Please turn off the power and the main switch of the machine (Please refer to the machine
manufacturer's instructions for operation).
After the power is turned off, there will be residual voltage in the system within a few
minutes. Make sure that the power indicator for the servo drive is off, then use a test
instrument to check the voltage between the terminals on the servo unit before starting
inspection work.
Clean the metal particles on the motor regularly.
Frequency of the inspections/tests/maintenance
HIWIN servo motor is a rotary actuator that allows for precise control of angular position,
velocity and acceleration. Improper operation or incorrect use environment will shorten the life
of the motor or even damage it. It is recommended to conduct measurement and maintenance
every quarter, please reference the following instructions for maintenance and inspection:
The detection mechanism or electrical connection must not be loosened.
Detect possible wear or aging of the cable.
Clean the dirt on the surface of the motor cover, brake cover, encoder cover with 70 %
alcohol.
Use the insulation resistance meter to test the isolation resistance of the three phases of
the motor. It must meet the requirements of 500 VDC for 1 second, >10M
Ω
@
25
°
C. If the
insulation resistance decreases gradually at the same temperature compared to the
previous several measurements, the motor may have begun to age, so special attention
should be paid.
