WHAT IS AN E007 FAULT – An E007 fault is a dc-bus over-voltage fault.
•
Check the dynamic braking resistor circuit. Check that the resistor is connected to the correct terminals RB & P+. Check if
the resistor is open using a mul�meter.
If the decelera�on �me is too short, try increasing the decelera�on �me.
•
If the resistor ohm value might be the incorrect value and a new resistor with a lower ohm value may be required.
•
If a regenera�ve unit is used, then check that the regenera�ve unit is online and func�oning correctly and not in a fault
•
status. Also check if the regenera�ve is going offline due to power imbalance or noise.
•
If the status of the fault was while at STOP then this typically points to the input power spiking. 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.

WHAT IS AN E014 and E030 FAULT – An E014 and E030 fault are both referenced as ground faults.
•
Check the output conductors for short to ground. Try disconnec�ng the motor leads from the VFD side and see if the fault
no longer persists.
Test the motor with a megger for insula�on break down or for corona discharge insula�on damage.
•
Check the motor for high moisture contamina�on.
