What does 81 mean?

Immediate switch-off with inhibit, specifically in "VFC hoist" operating mode. The motor could not be supplied with the correct current during pre-magnetizing time, possibly due to rated motor power being too small for the inverter or undersized motor cables. This prevents proper motor startup and can stress the inverter.
