Start Condition Error

What does 81 mean?

This fault occurs when the motor cannot be supplied with the correct amount of current during the pre-magnetizing time, particularly in hoist applications. This indicates an impedance mismatch or inadequate current capacity, preventing proper motor startup.

• Rated motor power is too small in relation to the rated inverter power.
• Motor cable cross-section is too small.

Click steps to track your progress.

1. 1

   Check the connection between the MOVIMOT inverter and the motor, verifying cable cross-section.

2. 2

   Verify that the rated motor power is appropriately matched with the rated inverter power.

3. 3

   Reset the fault by switching off and then switching on the DC 24V supply voltage.

4. 4

   Reset the error via the error reset function.
