013 Local control
(LOC CTRL/CONFIG.)
Value:
Local not active (DISABLE) [0]
Local control and open loop without slip com-
pensation
(LOC CTRL/OPEN LOOP)
[1]
Remote-operated control and open loop with-
out slip compensation
(LOC+DIG CTRL)
[2]
Local control as parameter 100
(LOC CTRL/AS P100)
[3]
Remote-operated control as parameter 100
(LOC+DIG CTRL/AS P100)
[4]
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], param-
eter 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 reference
.
When this choice is made, parameter 100 Configura-
tion automatically shifts to Speed regulation, 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 control-
led via the digital inputs.
For selections [1-2] control is shifted to open loop, no
slip compensation.
Local control as parameter 100 [3] is used when the
motor speed is to be set via parameter 003 Local ref-
erence , but without parameter 100 Configuration auto-
matically 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 control-
led via the digital inputs.
Shifting from Remote operation to Local operation in
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 direc-
tion of rotation will be maintained. If the present direc-
tion of rotation does not respond to the reversing 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 param-
eter has been set to Remote-operated control and open
loop [1]: The configuration selected in parameter 100
Configuration will be active. The shift will be smooth.
Shifting from Remote control to Local control in param-
eter 002 Local/remote operation , while this parameter
has been set to Remote-operated control as parameter
100 [4]: the present reference will be maintained. If the
reference signal is negative, the local reference will be
set to 0.
