It is not possible to evaluate the motor temperature for
encoder evaluations that are not inserted in slot C.
WARNING
<1>
The encoder connection may neither be closed nor removed when live!
The converter must be de-energized (24 V electronics power supply disconnected and DC link
fully discharged)!
