Servo Position Error (During Movement)

What does 411 mean?

The servo position error during movement is larger than the value specified in parameter No.182. This suggests that the motor is not accurately following its commanded trajectory during motion, indicating potential mechanical issues or inadequate control tuning.

• Mechanical cause of large position error during movement (e.g., excessive friction, load inertia mismatch, worn components).
• Parameter No.182 (position error limit during movement) is set too low for the application.
• Feed rate is too high for the system's capabilities.
• Insufficient time constants for proper control response.

1. 1

   Inspect the mechanical system for any sources of position error during movement (e.g., excessive friction, worn bearings, uncompensated load).

2. 2

   If no mechanical cause is found, specify a larger value for parameter No.182.

3. 3

   Specify a lower feed rate for the axial movement.

4. 4

   Increase the time constants (e.g., position loop gain, velocity loop gain parameters) to improve tracking performance.
