Fault Descriptions
Loss of communication with the network
Instantaneous Output Current has exceeded
inverter rated or programmed value
Heat sink Temperature Limit has been reached
Inverter has exceeded maximum or programmed
limit
DC Bus Voltage has exceeded inverter limit
DC Bus Voltage is lower than required inverter
limit
Inverter Output has shorted Phase to Phase
Inverter Output Grounding Current has
exceeded manufacturer
Motor is overloaded
Timed over current fault
Programmed limit for torque has been exceeded
External fault has been activated in the inverter.
This is a hard fault that must be reset
Inverter programming or operational interface
malfunction
Load on the Motor is less than programmed limit
of system. An Example is a broken belt or
coupling
Errors exist in the programmed or operational
configuration of the inverter
Required system operational feedback (signal or
sensor) is not responding as expected for correct
system operation
One or more of the output phases from the
inverter to the motor are open
Motor is operating in stall region and not able to
accelerate
Error sensed on the power section of the inverter
Input single phase or low line voltage condition
FC102 specific fault.
