10.1.4 Overvoltage and undervoltage monitoring for the intermediate circuit
The overvoltage monitoring for the intermediate circuit takes effect as soon as the intermediate circuit
voltage exceeds the operating voltage range. The undervoltage monitoring for the intermediate circuit
takes effect as soon as the intermediate circuit voltage falls below the operating voltage range. The
power output stage is switched off if exceeded or fallen below.
10.1.5 Output stage temperature monitoring
The output stage temperature is measured with a temperature sensor. In error management, the reac-
tion to the errors “Temperature of output stage is 5 °C below maximum” and “Over-temperature of
output stage” can be parametrised.
10.1.6 Monitoring of the motor
The motor controller has the following protective functions for monitoring the motor and the connected
motor shaft encoder:
Protective function Description
Monitoring the
shaft encoder
An error of the motor shaft encoder results in switching off of the power output
stage. Generally true for intelligent encoders is that their various error
messages are evaluated and reported by the motor controller as common error
“E 08-6” and “E 08-8”.
Measurement and
monitoring of the
motor
temperature
The motor controller can record and monitor the motor temperature through
the connection [X6].
In error management, the reaction to the error “overtemperature error (motor)”
can be parameterised.

10.1.7 I
2
t monitoring
The motor controller has I
2
t monitoring to limit the average power loss in the power output stage and in
the motor. As the power dissipation occurring in the power electronics and motor grows with the
square of the flowing current, the squared current value is assumed as the dimension of the power
loss.
