Speed Error

Hva betyr 61 ?

The measured motor speed deviates significantly from the commanded speed reference. For Permanent Magnet Synchronous (PMS) motors, this can also indicate that the motor has exceeded its pull-out torque, leading to loss of synchronization.

• Motor speed deviates significantly from the setpoint (e.g., P1-01).
• Inadequate torque to maintain speed under load.
• Encoder feedback issues (e.g., lost pulses, incorrect resolution).
• Tuning parameters (e.g., P2-01 to P2-06) not optimized.
• Mechanical system exhibiting resonance or instability.

1. 1

   Inspect the encoder connection and wiring to ensure proper speed feedback to the drive.

2. 2

   Verify motor loading and ensure the motor is not operating beyond its pull-out torque capacity, especially for PMS motors.
