Excessive Position Error Amount During Move

Hva betyr 411 ?

This alarm signifies that during axis movement, the actual position of the servo motor deviates from the commanded position by an amount greater than the allowed tolerance. This indicates the servo system is struggling to follow the commanded trajectory, potentially leading to inaccurate machining or unstable operation.

• Excessive mechanical load on the axis, exceeding the motor's or amplifier's capacity.
• Insufficient servo gain settings (e.g., position gain Parameter 1825, velocity gain Parameter 1826) for the load and acceleration requirements.
• Mechanical binding or high friction in the axis movement.
• Faulty encoder or feedback system providing incorrect position data.
• Malfunctioning servo motor or amplifier unable to provide commanded torque.

1. 1

   Inspect the mechanical system for binding, high friction, or damage to components that hinder smooth movement.

2. 2

   Adjust servo gain parameters (e.g., Parameter 1825 for position loop gain, Parameter 1826 for velocity loop gain) incrementally while observing axis response and stability.

3. 3

   Verify that the axis is not being overloaded beyond the servo motor's continuous torque rating during commanded movements.

4. 4

   Check the encoder feedback signal integrity, looking for intermittent loss or noisy signals, and ensure secure connections.

5. 5

   Test the servo motor and amplifier for proper functionality, potentially by swapping components if a spare or similar axis is available.
