WHAT IS AN E001, E005, and E039 FAULT – The 3 faults are all over-current type faults.
•
If opera�ng in closed loop AA121 = 10 then check the encoder sha� collar is �ght on the sha� and the encoder tether is
secure.
When the thermal protec�on begins, [E005] motor electronic thermal error occurs.
•
Irrespec�ve of the thermal se�ng of the motor, the inverter electronic thermal protec�on works independently to protect
•
the inverter.
•
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 at frequency decreased
from 5Hz and 80% at 0Hz.
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 less than 125% of the motor FLA.
•
Check for binding or obstruc�ons preven�ng the drive train from rota�ng.
•
If a load brake is present, check to see if the load brake is releasing and opera�ng correctly.
•
Check motor wiring.

WHAT IS AN E006 FAULT – An E006 fault is a dynamic braking overuse fault. This means the dynamic braking usage ra�o 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
enough period of �me and the braking chopper was trying to reduce the dc-bus voltage level. Check the incoming power
for spikes or if large machinery is star�ng up causing sags and spikes. 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 dynamic braking allowable usage will be set to 3% to detect when the load brake has excess wear and needs to be
serviced.
If the status of the fault was during RUN and the hoist is opera�ng in closed loop AA121 = 10 then the dynamic braking
•
allowable usage ra�o may not be set properly, contact Detroit Hoist for assistance in correc�ng this issue.
