SAFETY PRECAUTIONS
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,
the relative position (zero position) between the encoder and the motor winding is
changed, which causes the motor out of running!
2. In the normal climate, measure the insulation resistance which the motor winding is
against with the case, by 500V megameter, and the value should NOT be less than 20
MΩ.
3. The motor and the drive 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 case.
6. Only the qualified person can adjust and maintain the motor.
7. It is forbidden to move the motor by dragging the wire (cable) or the motor shaft.
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.
The incorrect connection and operation may cause the accident, so
before using and operating the motor, please read the manual carefully!

RESPONSIBILITY
Responsibility of the manufacturer
——The manufacturer should be in charge of the design and the structure of the
motor and its accessories.
——The manufacturer should be responsible for the safety of the motor and its
accessories.
——The manufacturer should be in charge of the provided information and
suggestion for the user.
Responsibility of the end user
——The user should be very familiar with the safety operation through learning
the motor safety operation or participating in the training session.
——The user should be responsible for the safety after adding, changing or
modifying the original motor and its accessories by himself.
——The user should be in charge of the danger resulted from the operation,
adjusting, maintenance, installation and storage which are not complied
with the manual regulation.
The manual is kept by the end user.

ⅠPRODUCT CHARACTERISTICS
SJT series sine shaped AC permanent magnet synchronous servo motor, which is researched,
developed and manufactured by GSK, adopts the rare earth permanent magnet material of high
performance, with the characteristics of high torque inertia ratio, low speed performance, strong
overload capacity and high reliability etc, which can widely satisfy the requirements of the machine
CNC system and automation.
ⅡRUNNING CONDITIONS
2.1 The height above sea level should NOT exceed 1000m. If it’s more than 1000m, some
performance may get affected due to the air cooling.
2.2 The environment temperature should be in the range of -10℃~ +40℃.
2.3 The relative air humidity is ≤90% (without the condensation).
2.4 AC voltage value of steady state is:（0.85 ~1.1）multiplies the rated voltage value.
