4.4.3 Overload Alarm
An overload alarm will occur only when the motor is running and the current rises above
the programmed
OVERLOAD ALARM LEVEL. The overload alarm is disabled during a start.
An application of an unlatched overload alarm is to signal a PLC that controls the load on
the motor, whenever the motor is too heavily loaded.
