External stop signals activated by means of control
signals or a serial bus will override a "start" command via
the LCP.
[Off]
stops the connected motor. The key can be selected as Enable
[1] or Disable [0] via par. 0-41 [Off] Key on LCP. If no external
stop function is selected and the [Off] key is inactive the motor
can only be stopped by disconnecting the mains supply.

frequency converter will start. The key can be selected as

An active HAND-OFF-AUTO signal via the digital inputs
has higher priority than the control keys [Hand on] –

par. 0-43 [Reset] Key on LCP.
The parameter shortcut can be carried out by holding down
the [Main Menu] key for 3 seconds. The parameter shortcut
allows direct access to any parameter.
