Angle overflow (Detection not possible)

What does P13 mean?

This fault typically occurs in position control applications and indicates that the internal position counter or angle calculation has overflowed or reached an invalid state, making accurate position detection impossible. This could be due to excessive speed, incorrect scaling, or feedback issues. By default, this critical condition triggers a full TRIP, inhibiting all ignition pulses and resetting the Ready signal, as accurate position is lost. Manual reset is required.

Complete Troubleshooting Guide

1. 1

   Check encoder/resolver operation: Verify the feedback device is functioning correctly and providing a stable signal without dropouts.

2. 2

   Review scaling parameters: Ensure all position and velocity scaling parameters in the drive (e.g., encoder pulses per revolution, gear ratios) are correctly configured.

3. 3

   Reduce maximum speed/acceleration: If the application allows, reduce the commanded speed or acceleration to prevent the internal counter from overflowing.

4. 4

   Inspect for mechanical slippage: Ensure there is no slippage between the motor shaft and the feedback device.

5. 5

   Verify control mode: Confirm the drive is in the appropriate control mode for the application (e.g., position control).
