Acknowledge error (RESET)
Whenever an error occurs, the motor controller goes into error status (READY=0).
Acknowledgeable
errors (

Chapter 6.3.2) can be reset by pressing RESET. If the error cannot be acknowledged, the
controller must be restarted.
In a few cases, acknowledgement is possible immediately, e.g. with a drag error. In other cases, the
troubleshooting must be remedied first (e.g. temperature error, load voltage error).
Shortly after acknowledging the error (RESET 0

flank (CONTROL ENABLE 0

is required. After that, the motor controller is once again ready for op
