010 Small display line 1.1
(DISPLAY LINE 1.1)
Value:
See par. 009 Large display readout
Function:
In this parameter, the first of three data values
can be selected that is to be displayed in the
LCP control unit display, line 1, position 1. This
is a useful function, e.g. when setting the PID
regulator, as it gi v es a view of process reactions to
reference changes. The display readout is acti v ated
by pushing the [DISPLAY STATUS] key.
Description of choice:
See parameter 009 Large display readout.
011 Small display readout 1.2
(DISPLAY LINE 1.2)
Value:
See parameter 009 Large display readout
Function:
See the functional description gi v en under parameter
010 Small display readout.
Description of choice:
See parameter 009 Large display readout.
012 Small display readout 1.3
(DISPLAY LINE 1.3)
Value:
See parameter 009 Large display readout
Function:
See the functional description gi v en under parameter
010 Small display readout.
Description of choice:
See parameter 009 Large display readout.

(LOC CTRL/OPEN LOOP)
Remote-operated control and open loop
without slip compensation
(LOC+DIG CTRL)
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
operation [1] has been chosen.
Description of choice:
If Local not acti v e [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 acti v e
[0], parameter 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 Configuration
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 controlled via the digital inputs.
Local control as parameter 100 [3] is used when
the motor speed is to be set via parameter
003 Local 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 parameter 002 Local/remote operation, while this
parameter 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 reversing
signal (negati v e reference), the reference will be set to 0.
Shifting from Local operation to Remote operation
in parameter 002 Local/remote control, while
this parameter has been set to Remote-operated
control and open loop [1]: The configuration
selected in parameter 100 Configuration will be
acti v e. The shift will be smooth.
