Deviation in Speed

Hva betyr 7 ?

This error indicates a significant difference between the commanded speed and the actual motor speed, exceeding an allowed tolerance. This suggests a problem with the drive's speed control, speed feedback mechanism, or a mechanical issue affecting motor speed.

• Incorrect PID controller tuning in the drive's speed control loop.
• Malfunction or complete loss of feedback from the speed encoder or resolver (if used).
• Mechanical binding, excessive friction, or damage within the load.
• Insufficient motor torque to achieve the commanded speed due to severe overload.

1. 1

   Verify the functionality and connections of the speed feedback device (e.g., encoder, resolver) for proper signal integrity.

2. 2

   Check the actual motor speed against the commanded speed using the drive's diagnostic tools or an external tachometer.

3. 3

   Adjust the speed control PID parameters (proportional, integral, derivative gains) in the drive for improved response and stability.

4. 4

   Inspect the mechanical system for any physical obstructions or signs of excessive friction that could impede motor speed.
