Start/Stop Parameters

P3.2.1 REMOTE CONTROL PLACE (ID 172)
You can use this parameter to select the remote control place (start/stop).
You can use this parameter to change back to remote control from PC, for example if the control panel is broken.
P3.2.2 LOCAL/REMOTE (ID 211)
You can use this parameter to switch between the local and remote control places.
Local control place is always keypad control. The remote control place can be I/O or Fieldbus, depending on the
parameter value Remote Control Place.
P3.2.3 KEYPAD MASTER-STOP (ID 1806)
You can use this parameter to enable the Keypad Master-stop function.
When this parameter is enabled, you can force the drive to the stop state from the keypad stop button even if it is
controlled from another control place (Remote). If you stop the drive with this function, the drive goes to the lock
state. To restart the drive in Remote mode, you need to first press the BACK/RESET button and then press the
Start button.
You can also change the control to Local and start there but when you go back to the Remote mode, you still need
to press the Start button. This also applies after a power-down as the state of this function is retained in memory.
