How to start, stop and switch between local and remote control
You can start, stop and switch between local and remote control in any mode. To be
able to start or stop the drive, the drive must be in local control.
Step Action Display

• To switch between remote control (REM shown on the left) and local
control (LOC shown on the left), press
LOC
.
REM
Note: Switching to local control can be disabled with parameter 1606
LOCAL LOCK.
After pressing the key, the display briefly shows messa
ge “LoC” or “rE”,
as appropriate, before returning to the previous display.
The very first time the drive is powered up, it is in remote control (REM) and
controlled through the drive I/O terminals. To switch to local control (LOC)
and control the drive using the control panel and the integrated
potentiometer, press
LOC . The result depends on how long you press the
REM
key:
• If you release the key immediately (the display flashes “LoC”), the drive
stops. Set the local control reference with the potentiometer.
• If you press the key for about two seconds (release when the display
changes from
“LoC” to “LoC r”), the drive continues as before, except that
the current position of the potentiometer determines the local reference (if
there is a great difference between the remote and local references, the
transfer from remote to local control is not smooth). The drive copies the
current remote value for run/stop status and uses it as the initial local
run/stop setting.
• To stop the drive in local control, press
to stop.
• To start the drive in local control, press
to start.
