WARNING
Automatic restart
Danger of death, serious injury, or property damage.
The automatic reset mode (AUTO RESET) must not be used in applications where there
is a risk of serious injury to persons or substantial damage to property if the motor starts
up again unexpectedly. The start command (e.g. issued by a contact or the PLC) must
be reset prior to issuing a RESET command because the motor attempts to restart
again automatically following this RESET command if a start command is still present.
This particularly applies if the motor protection has tripped. For safety reasons, you are
advised to integrate the group fault output (terminals 95 and 96) in the controller.
