(DISPLAY LINE 1.3)
Value:
See parameter 009 Large display readout
Function:
See the functional description given under parameter
010 Small display readout.
Description of choice:
See parameter 009 Large display readout.
013 Local control

(LOC CTRL/CONFIG.)
Value:
Local not active (DISABLE)
Local control and open loop
(LOC CTRL/OPEN LOOP)
Remote-operated control and open loop
(LOC+DIG CTRL/AS P100)
Local control as parameter 100
(LOC CTRL/AS P100)
Remote-operated control as parameter 100
(LOC+DIG CTRL/AS P100)
Function:
This is where the required function is selected if, in
parameter 002 Local/remote operation, Local opera-
tion [1] has been chosen.
Description of choice:
If Local not active [0] is selected, it is not possible to
set a reference via parameter 003 Local reference.
In order to enable a shift to Local not active [0], pa-
rameter 002 Local/remote operation must be set to
Remote operation [0].
Local control and open loop [1] is used if the motor
speed is to be set via parameter 003 Local refer-
ence. When this choice is made, parameter 100
Configuration automatically shifts to Speed regula-
tion, open loop [0].
Remote-operated control and open loop [2] functions
in the same way as Local control and open loop [1];
however, the frequency converter can also be con-
trolled via the digital inputs.
Local control as parameter 100 [3] is used when the
motor speed is to be set via parameter 003 Local
= factory setting. () = display text [] = value for use in communication via serial communication port

reference, but without parameter 100 Configuration
automatically shifting to Speed regulation, open loop
[0].
Remote-operated control as parameter 100 [4]
works the same way as Local control as parameter
100 [3]; however, the frequency converter can also
be controlled via the digital inputs.
Shifting from Remote operation to Local operation in
Power [kW][8]
parameter 002 Local/remote operation, while this pa-
rameter has been set to Remote-operated control
and open loop [1]: The present motor frequency and
direction of rotation will be maintained. If the present
direction of rotation does not respond to the revers-
ing signal (negative reference), the reference will be
set to 0.
Shifting from Local operation to Remote operation in
parameter 002 Local/remote control, while this pa-
rameter has been set to Remote-operated control
and open loop [1]: The configuration selected in pa-
rameter 100 Configuration will be active. The shift
[0]
will be smooth.

Shifting from Remote control to Local control in
parameter 002 Local/remote operation, while this pa-
[2]
rameter has been set to Remote-operated control as
parameter 100 [4]: the present reference will be
[3]
maintained. If the reference signal is negative, the
local reference will be set to 0.
[4]
Shifting from Local operation to Remote operation in
parameter 002 Local/remote operation, while this pa-
rameter has been set to Remote operation: The
local reference will be replaced by the remote-
operated reference signal.
014 Local stop
014
Value:
Not active (DISABLE)
Active (ENABLE)
Function:
In this parameter, the local [STOP]-key can be en-
gaged or disengaged on the control panel and on
the LCP control panel.
Description of choice:
If Not active [0] is selected in this parameter, the
[STOP]-key will be inactive.
