Overview
The ARS 2300 servo drive has an extensive sensor system monitoring the operation of the controller
unit, power output stage, motor and communication with the outside world. Any occurring errors are
stored in an internal error memory. Most errors will cause the controller unit to shut down the servo
drive and the power output stage. They can only be switched on again after the error memory has
been deleted by acknowledging the error and after the error has been eliminated or ceased to exist.
An extensive sensor system and numerous monitoring functions ensure operational safety:
Motor temperature measurement and monitoring
Power module temperature measurement
Detection of ground faults (PE)
Detection of connections between two motor phases
Detection of supply phase failure
Detection of supply mains failure
Detection of overvoltage in the DC bus
Detection of errors concerning the internal voltage supply
Breakdown of the supply voltage
If the 24 V DC supply voltage fails, approx. 20 ms remain to save parameters and shut down the
control properly for example.
10.1.2
Phase and mains failure detection
In three-phase operation, the ARS 2300 servo drive detects failure of one phase (phase failure
detection) or of several phases (mains failure detection) of the mains supply of the device.
