What to do if the Danaher SERVOSTAR 343 motor does not rotate?

  Jessica GomezAug 14, 2025
  If the Danaher Amplifier motor isn't rotating, several factors could be at play. First, ensure the servo amplifier is enabled by applying the ENABLE signal and verify that the software enable is set. Check the setpoint cable for any breaks and confirm the motor phase sequence is correct. Also, ensure the brake is released by checking the brake control, and verify that the drive is not mechanically blocked. Finally, confirm that the motor pole number and feedback are set up correctly.

Why does the Danaher SERVOSTAR 343 Amplifier motor oscillate?
- A
  Adam ChaseAug 17, 2025
  If the Danaher Amplifier motor oscillates, it could be due to a few reasons. The gain might be too high, so try reducing Kp (speed controller). Also, check the feedback cable shielding for breaks and replace the cable if needed. Finally, ensure that AGND is properly wired to CNC-GND.

What to do if Danaher SERVOSTAR 343 drive reports following error?
- C
  Cynthia LongAug 21, 2025
  If your Danaher Amplifier drive reports a following error, it might be because Irms or Ipeak is set too low. Increase Irms or Ipeak, but be sure to stay within the motor's ratings. Also, the accel/decel ramp might be too long, so try shortening the ramp.

Why is the Danaher SERVOSTAR 343 motor overheating?
- A
  Alicia FuentesAug 26, 2025
  If the Danaher Amplifier motor is overheating, it's likely that the Irms/Ipeak setting is too high. Reduce the Irms/Ipeak to resolve this issue.

  A 'Communication fault' message on the Danaher Amplifier HMI could stem from several issues. Ensure you're using a null-modem cable and that it's plugged into the correct sockets on both the servo amplifier and the PC. Also, verify that the correct PC interface is selected.

Why is the Danaher Amplifier drive too soft?
- B
  Barbara VasquezSep 1, 2025
  If the Danaher Amplifier drive feels too soft, it could be due to several settings. Try increasing Kp (speed controller). If that doesn't work, ensure Tn (speed controller) is set to the motor's default value. Also, try reducing ARLPF / ARHPF and ARLP2.

Why does the Danaher Amplifier drive run roughly?
- J
  James WallaceSep 5, 2025
  If the Danaher Amplifier drive runs roughly, it may be due to incorrect settings. Try reducing Kp (speed controller). If the issue persists, use the motor default value for Tn (speed controller). Also, increase ARLPF / ARHPF and ARLP2.

What to do if Danaher SERVOSTAR 343 Amplifier axis drifts at setpoint = 0V?
- H
  Heather DeanSep 9, 2025
  If the Danaher Amplifier axis drifts at setpoint = 0V, it could be due to the offset not being correctly adjusted for analog setpoint provision. Adjust the offset (analog I/O) to correct this. Another potential cause is that AGND is not joined to the controller-GND of the controls; ensure these are joined.
