Overcurrent in output stage

What does F1.2 mean?

The motor current flowing through the output stage is excessively high, potentially due to an undersized motor, issues with the current supply or transformer, incorrect ramp times, a defective phase module, or an unstable 24 V supply. This condition can lead to severe damage to both the drive and the motor if not corrected.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If the ramp limit is deactivated and the ramp time is too short, increase the deceleration ramp time.

2. 4

   Inspect the phase module for defects and check the 24 V supply voltage for stability.

3. 5

   Examine the signal lines of the phase modules for interruptions or short circuits.
