Open Output (VFC Hoist)

Hva betyr 82 ?

Immediate switch-off, specific to 'VFC hoist' operating mode, indicating that two or all output phases to the motor are interrupted, or that the rated motor power is too small compared to the inverter's rated power. This results in an inability to power the motor correctly.

• An output assigned for the VFC Hoist application is open circuit.
• Faulty contactor or relay in the hoist motor control circuit.
• Wiring issue to the hoist motor output.
• Output driver failure.
