Output Short Circuit

What does OC1 mean?

A short circuit has been detected on the drive's output, possibly in the motor, motor cables, or brake resistor circuit. Excessive capacitive charging current from long or high-capacitance motor cables can also falsely trigger this fault. An unresolved short circuit poses a severe risk of damage to the drive's output stage.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If motor cables are excessively long or high-capacitance, consider using shorter or lower-capacitance motor cables.
