Output Open Detected

What does 82 mean?

This fault signifies that the measured output current for either drive 1 or drive 2 is less than 2% of the unit's nominal current (IN,unit/device) when the respective drive is enabled. This strongly suggests an open circuit in the motor circuit, such as a disconnected or broken motor cable, a faulty motor winding, or an issue with the drive's output stage itself. This condition prevents motor operation and could indicate significant wiring or motor damage, posing a risk of component failure if the unit attempts to drive into an open circuit.

Complete Troubleshooting Guide

1. 1

   Thoroughly inspect the motor cable for the affected drive (drive 1 or drive 2) for any physical damage, breaks, or loose connections at both the MOVIFIT unit and the motor terminal box.

2. 2

   Check the continuity of the motor windings and the motor cable using a multimeter to identify any open circuits.

3. 3

   Verify that all terminals connecting the motor to the MOVIFIT unit are securely fastened and making good electrical contact.

4. 4

   If possible, perform an insulation resistance test on the motor and cable to rule out internal winding failures or hidden damage.
