8.1.4
Voltage monitoring for the intermediate circuit
Voltage monitoring for the intermediate circuit is triggered as soon as the intermediate
circuit voltage leaves the operating voltage range. The power end stage is then
deactivated.
8.1.5
I²t monitoring
The CMMD-AS motor controller has l²t monitoring to restrict the average power loss in the
power end stage and in the motor. Since the power loss which occurs in the power
electronics and in the motor increases by its square as the current flow increases in a
worst case scenario, the square of the current value is usually assumed for the power
loss.
8.1.6
Temperature monitoring for the heat sink
The heat sink temperature of the final output stage is measured with a linear temperature
sensor. Temperature monitoring is triggered at temperatures above 85
°C. A temperature
warning is issued at 80
°C.
8.1.7
Power monitoring for the brake chopper
Power monitoring for the internal braking resistor is available in the operating software.
