Protective Circuits
Short Circuit Protection
The Aries Controller drive has an internal circuit that protects it from short
circuits between one motor terminal to another (phase to phase), or from any
motor terminal to earth.

Cycle power to the drive/controller.
–or–
Open ACR-View and issue the DRIVE RES AXIS0 command to the Aries
Controller.
Drive/Controller Over-Temperature Protection
The Aries Controller over-temperature circuit monitors the drive/controller’s
internal temperature. If the sensors exceed the threshold temperature, the
unit issues an over-temperature fault.
Threshold Temperature
AR-04CE, AR-08CE, and AR-13CE 80°C (176°F)
