Why is my Parker Servo Drives motor becoming unusually hot?
- R
  Richard PrestonJul 27, 2025
  Your Parker Servo Drives motor might be overheating due to several reasons. It may be overloaded, or the rotation speed could be too low. Check the current and the operating cycle of the torque motor. Also, verify if the mounting surface is sufficient and not acting as a heat source. High friction in the machine may also be the cause, so test the motor current with and without a load and check that the motor does not have thermal insulation.

  To address vibrations in your Parker Servo Drives system, check the encoder and tachometer connections, the earth connections, and the earthing of the earth wire. Also, review the setting of the servo drive speed loop, tachometer screening and filtering. Ensure the stability of the secondary voltages and verify the rigidity of the frame and motor support.

What to do if I have difficulty starting my Parker K Series motor?
- B
  bmcdowellAug 9, 2025
  If you're having trouble starting your Parker Servo Drives motor, check the fuses, the voltage at the terminals, and the load current. Also, check the power supply to the brake (+ 24 V ± 10 %) and its polarity. Verify any thermal protection, its connection, and how it is set in the drive. Finally, check the servomotor insulation. The minimum insulation resistance value measured under a max. 50V DC is 50 MΩ between the phase and the casing, between the thermal protection and the casing, between the brake coil and the casing, and between the resolver coils and the casing. The issue could also be due to an overload or jammed bearings.

Why is my Parker K Series motor racing?
- P
  Priscilla MartinAug 13, 2025
  If your Parker Servo Drives motor is racing, check the speed set-point of the servo drive. Also, ensure that you are in speed regulation and not in torque regulation. Verify the encoder setting and the servomotor phase order: U, V, W.

Why is my Parker Servo Drives motor too noisy?
- A
  Angelica JimenezAug 18, 2025
  The noise in your Parker Servo Drives motor could stem from several mechanical issues, such as unsatisfactory mechanical balancing, friction from the brake, a defective coupling, or loosening of several pieces. Also, check rotation in open loop if there is poor adjustment of servo drive or position loop.

What to do if Parker K Series Servo Drives motor does not turn by hand?
- N
  Natalie LivingstonAug 22, 2025
  If your Parker Servo Drives motor does not turn by hand when not connected to the drive, check that there is no mechanical blockage or if the motor terminals are not short-circuited. Also, check the power supply to the brake.
