Start condition

Hva betyr F81 ?

An immediate switch-off with inhibit occurs only in 'VFC hoist' operating mode. The motor could not be supplied with the correct amount of current during the pre-magnetizing time, possibly due to mismatched motor/inverter power or insufficient motor cable cross-section.

• Motor could not be supplied with correct current during pre-magnetizing time (VFC hoist mode)
• Rated motor power too small in relation to rated inverter power
• Motor cable cross section too small

1. 1

   Check the connection between the inverter and motor for integrity and correct phasing

2. 2

   Check startup data, including motor parameters, and perform a new startup procedure if necessary

3. 3

   Check the cross section of the motor cable and increase it if necessary to ensure adequate current delivery
