What does 81 mean?

Immediate switch-off, specific to 'VFC hoist' operating mode, occurring when the motor cannot be supplied with the correct current during pre-magnetizing time. This typically happens if the rated motor power is too small relative to the inverter, or if the motor cable cross-section is insufficient.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Check the cross-section of the motor cable and increase it if necessary to ensure adequate current delivery without excessive voltage drop.
