Faults and alarms
The following table specifies the faults and alarms that the Motor Overtemperature
Detection function declares.
Fault/Alarm Description
Motor over temp Occurs when the state of the motor overtemperature
circuit is Force False, indicating that the circuit is open,
and parameter Motor OT fault mode is set to Trip flt
Motor temp hot
Occurs when the state of the motor overtemperature
circuit is Force False, indicating that the circuit is open,
and parameter Motor OT fault mode is set to Alarm fault
Function description
The parameters Motor OT fault sel generally selects digital inputs (variables Digital
input 1, …, Digital input 6). The Motor Overtemperature Detection may be disabled
by setting Motor OT fault sel equal to Unused.
Phase Current Protection
The drive contains several diagnostic and protective features involving the Phase
Current Protection.
Diagnostic variables
The following table specifies the Phase Current Protection diagnostic variables.
Variable Description
Phase A current Filtered phase A current. Amps
Phase B current Filtered phase B current. Amps
Phase C current Filtered phase C current. Amps
Phs A current offset Calculated phase A current offset. Amps
Phs B current offset Calculated phase B current offset. Amps
Phs C current offset Calculated phase C current offset. Amps
Faults and alarms
The following table specifies the faults and alarms associated with the Phase Current
Protection.
Fault/Alarm Description
Phase A cur offset
Trip fault that occurs when the phase A current offset is
too high.
Phase B cur offset Trip fault that occurs when the phase B current offset is
too high.
Phase C cur offset Trip fault that occurs when the phase C current offset is
too high.
