Reset Fault Using Input; Output Signal When Fault Occurs; Electronic Motor Thermal Protection - Hitachi WJ200 Instruction Manual

RESET FAULT USING INPUT

Resetting a fault remotely using an input to the VFD can be done by configuring one of the available digital inputs for reset. Use the
chart below.
Function
Fault reset

OUTPUT SIGNAL WHEN FAULT OCCURS

You can configure a 24v digital output to turn on when a fault occurs. If the VFD is configured for hoisting, then you will need to
configure the over-weight logic for either maintained or internal in order to free up digital output 12. If you need to change the over-
weight logic, please reference the hoist over-weight function section to change the logic to maintained or internal.

Output 12 Off-Delay Time

ELECTRONIC MOTOR THERMAL PROTECTION

The VFD has a built-in electronic motor thermal protection function and is configured for constant torque loading. When the output
current exceeds the value in b012 for a calculated time based on frequency and time the VFD will trip with an E05 fault.
