• When the current grows rapidly, [E001] excessive current error could occur before [E005] motor electronic thermal error.
• Even if the electronic thermal level is set high, the electronic thermal for inverter works separately
• Check to see if the motor brake is releasing correctly.
• Check if parameter bC110 value is set to lower than the over-weight value or

TROUBLESHOOTING E006 FAULT
WHAT IS AN E006 FAULT – An E006 fault is a dynamic braking overuse fault. This means the dynamic braking usage ratio was
exceeded or met.
• If the status of the fault was while at STOP then this typically points to the input power to the VFD increased for a long
-bus voltage level. Check the incoming power for
spikes or if l If this is the case, then try adding a line reactor in front of
the main power of the crane.
• If the status of the fault was during RUN and the hoist has a load brake, then the load brake needs to be serviced. The VFD’s
