Troubleshooting E016 Fault - Hitachi P1 Basic Instruction Manual

WHAT IS AN E016 FAULT – An E016 fault is an instantaneous power failure fault. When the power is removed and restored within a
very short period the VFD will detect that as an instantaneous power failure and will fault to protect the VFD and motor.
Check the incoming power for sags 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.
• Check if the mainline or power supply disconnect / switch / contactor is func�oning correctly.
• If the problem is based on sags, then changing the control circuit power supply from the incoming AC lines to tapping the
dc-bus may reduce the chance of an E016 fault, see image below modified red circuit as reference to changing the circuit.
