3. Troubleshooting
Unstable Rotation (Not Smooth),
Motor Runs Slowly Even with Speed Zero at Velocity Control Mode
position control mode, the motor runs slowly at servo-ON due to
or the waveform graphic function of the PANATERM. Review the
wiring, connector contact failure and controller.
Correct the wiring and connection so that the Servo-ON signal
can be turned on normally. Review the controller.
2) Check the wiring and connection between Pin-18 and 17, 16 and
