WARNING
!
Automatic motor restart.
Can cause death, serious personal injury or property damage.
Do not use automatic reset mode when unexpected automatic restart of the motor can occur and cause injury to persons or damage to
equipment.
The Start command (e.g. via the PLC) must be canceled before a Reset command is given, since an automatic restart is executed after
the Reset command when the Start command is still pending. This applies in particular in the case of motor protection tripping. For
safety reasons, it is recommended to integrate the group error output (terminals 95 and 96) into the controller.
