Overcurrent Trip

What does Overcurrent mean?

An excessive current flow has been detected at the drive's output. This is typically caused by a short circuit or ground fault on the output side, an extremely heavy mechanical load, overly short acceleration/deceleration times, incorrect motor data, or switching a magnetic contactor at the output. This condition can severely damage the drive's power section (IGBTs).

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Review and adjust drive parameters for acceleration/deceleration times, motor data, and V/f pattern settings.

2. 4

   Ensure that no magnetic contactor or switching device is operating on the drive's output side during motor operation.
