4.25.3.10 Derating
In order to be able to operate the motor module over the entire temperature range, only modules with a maximum
power loss of of 0.5 W can be installed next to the motor module or respective turn-off times must be implemented.
If the neighboring modules have a higher power loss and all channels are operated continuously, the motor current
must be derated.
When a motor is switched on, the current is increased for a short time. This behavior has no influence on the
derating.
Current derating 1 of the motor module
Current derating for the motor module for neighboring modules with ≤1.8 W thermal power loss.
