ABB DO880 3BSE028602R1 Digital Output

Overcurrent and short-circuit monitoring The overcurrent and short-circuit monitoring detects short-circuits between two motor phases as well as short-circuits at the motor output terminals against the positive and negative reference potential of the DC bus and against PE. If the error monitoring detects an overcurrent, the power output stage will be shut down immediately to guarantee the ability to withstand short-circuits. 11.1.3 Overvoltage monitoring for the DC bus This monitor responds, if the DC bus voltage exceeds the operating voltage range. The power output stage will be shut down.

Monitoring of the motor 

The ARS 2100 SE series servo drives have the following protective functions to monitor the motor and the connected encoder: Monitoring of the encoder: An error of the shaft encoder leads to the shut-down of the power output stage. In the case of resolvers, for example the encoder signal is monitored. In the case of incremental encoders the commutation signals are checked. Other “intelligent” encoders provide further means of error detection. Measurement and monitoring of the motor temperature: The ARS 2100 SE series servo drives have a digital and analogue input for measuring and monitoring the motor temperature. The analogue signal detection also supports non-linear sensors

The heat sink temperature of the power output stage is measured with a linear temperature sensor. The temperature limit varies from device type to device type

Power monitoring for the brake chopper

 Power monitoring for the internal brake resistor is implemented in the operating software. When the power monitoring “I²t brake chopper” reaches 100% the power of the internal brake resistor is switched back to the rated output power.The ARS 2100 SE servo drives comprise an I²t monitoring to limit the average power loss in the power output stage and in the motor. Since the occurring power loss in the power electronics and in the motor in the worst case increases square with the current, the squared current value is assumed as the measure for the power loss
