The current error status of the drive is indicated in this register. Each bit indicates a certain error or status. If an
error is registered in bits 0 to 3, then the corresponding bit remains set until the error has been acknowledged (see
"Module configuration 2" and "Error acknowledgment").

Overtemperature error
The "Overtemperature" error bit can be set for the following reasons:
•
A specific temperature was exceeded near the channel due to overload
•
Module temperature exceeds 85°C
Current error
This error bit occurs whenever the required current cannot be supplied to the motor windings. This can be (but
is not necessarily) caused by an open line. At higher speeds (depending on the motor), this error can also occur
without an open line. In this case it is simply no longer possible to supply the desired current to the motor windings.
Because of the Back-EMF on the motor, this bit is set at slightly lower speeds if the motor is operated with no load
compared with full or partial loads.
