Resetting the fault
After the internal temperature has dropped below the values shown in Table
54, you can clear the latched fault. There are two methods available:
► Cycle power to the Aries drive.
–or–
► Open the Aries Support Tool. Then select Operating System Update
from the menu and click Reset Drive.
Model Reset Temperature
AR-01xx, AR-02xx, AR-04xx,
AR-08xx, and AR-13xx 75°C (167°F)
AR-20xE and AR-30xE 85°C (185°F)
Table 54 Reset Temperature Values
Under-Voltage Protection The Aries drive’s under voltage protection circuit monitors AC input voltage. If
the voltage falls below a specific value while the drive is operating, the drive
issues an under-voltage fault and turns off power to the motor output
terminals (MOTOR connector). This allows the motor to freewheel to a stop.
Threshold Voltage
AR-01xx, AR-02xx, AR-04xx,
AR-08xx, and AR-13xx........................... Voltage below 70 VAC trips fault
AR-20xE and AR-30xE........................... Voltage below 160 VAC trips fault
Results of Fault....................................... Power to motor is turned off
Fault output is activated

Resetting the fault
To clear the latched fault, choose one of the following methods:
► Cycle power to the Aries drive.
–or–
► Open the Aries Support Tool. Then select Operating System Update
from the menu and click Reset Drive.
Warning — When an under-voltage protection fault occurs, the drive
disables power to its motor output terminals on the Motor connector. This
cuts all control to the motor and allows the load to freewheel to a stop.
