Axis Overcurrent

What does OVERCURRENT Ax mean?

This fault indicates an overcurrent condition on the specified axis (Ax). Possible causes include overloading of the axis or an I²t overload. A defective KSD module could also be the root cause.

• Mechanical overload on the motor exceeding its rated current (P3-01).
• Incorrect motor tuning parameters, leading to excessive current draw.
• Short circuit in the motor windings or motor cable.
• Drive unit commanded to produce torque beyond its capability.
• Encoder feedback error causing incorrect current control (P4-xx).

Click steps to track your progress.

1. 1

   Reduce the load on the affected axis by decreasing the Override (OVR) setting in the robot program.

2. 2

   Reduce the acceleration for the affected axis using the `$ACC_AXIS` parameter.

3. 3

   If the issue persists, exchange the KSD module for the affected axis.
