GSK ZJY Series User manual

In this manual, we have tried as much as possible to describe all
the various matters about the spindle servo motor. However, we can
not describe all the matters which must not be done or which can not
be done because there are so many possibilities. Therefore, matters
which are not especially described in this manual should be regarded
as “impossible” or “forbidden”.

SAFETY PRECAUTION
The incorrect connection and operation may cause the accident, so
before using and operating the motor, please read the manual
carefully!
1. The motor is installed with the photoelectric encoder, and it’s not allowed to hit the
motor. And the user can’t disassemble the photoelectric encoder by himself; otherwise,
once the encoder is damaged, it may cause the motor out of running!
2. In the normal climate, measure the insulation resistance, which the motor winding is
against with the cabinet, by 1000V megameter, and the value should NOT be less than 20
MΩ.
3. The motor and the drive unit should be connected correctly based on the manual to
guarantee the protective grounding stable and reliable.
4. The motor can run with load only after the motor is free of noise and vibration during
running from zero speed to the maximum speed in the dry run state.
5. During the motor running, it’s not allowed to touch the motor shaft and cabinet.
6. Only the qualified person can adjust and maintain the motor.
7. It is forbidden to move the motor by dragging the wire (cable), the motor shaft or the
encoder.
8. GSK does NOT take any responsibility for any change on the product by the user, and
the warranty bill becomes invalid.
All specifications and designs are subject to change without notice.
