temperature. If the sensors exceed the threshold temperature, the drive
issues an over-temperature fault.
Threshold Temperature
AR-01xx, AR-02xx, AR-04xx,
AR-08xx, and AR-13xx ........................... 80°C (176°F)
AR-20xE and AR-30xE ........................... 90°C (194°F)
Results of Fault ....................................... Power to motor is turned off
Fault output is activated
