Troubleshooting
The servo amplifier has included some different protective functions. Under voltage and
over temperature are monitored and shown with the LED’s at the front side.
Important:
The motor starts after the failure is eliminated.
Motor oscillates
•
The gain of the servo amplifier is too high. Reduce the gain pot or in IxR mode the
the IxR pot.
Motor runaway
•
The feedback loop is open. Check wiring.
•
The polarity of the motor or of the tacho is permuted.
•
Check the encoder wiring.
•
No load at torque mode.
•
Reduce the maximal speed with pot n max.
Motor noise
•
Reduce gain with gain pot.
•
Use additional choke in the motor
Motor has no torque
•
Increase the admissible current with I max pot.
Motor drifts at standstill
•
Adjust the offset with the offset pot.
•
The input value for the set value isn’t stable.
Motor is going hot at standstill
•
Is the motor blocked?
Motor speed too low
•
Increase the range with pot n max.
•
Increase the admissible current with I max pot.
•
Supply voltage too low.
