010 Small display line 1.1
(DISPLAY LINE 1.1)
Value:
See par. 009 Large display readout
✭ Ana log input 53 [V] [17]
Function:
In this parame ter, 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 functi on, e.g. when setting the PID
regulator, as it gives a view of pro cess reactions to
reference cha nges. The display readout is activated
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
✭ Mo tor current [A][6]
Function:
See the functional desc ription given 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
✭ Feedback [unit] [3]
Function:
See the functional desc ription 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)
[0]
Local control and open loop w ithout slip
compensation
(LOC CTRL/OPEN LOOP)
[1]
Remote-operated control and open loop
without slip compensa t ion
(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
operation [1] has been chosen.
Description of choice:
If Local not active [0] is selected, it is not possible to
set a reference v ia parameter 003 Local reference.
In order to enable a shift to Local not active
[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 Loc al reference.
When this choice is made, parameter 100 Configuration
automatically shifts to Speed regulation, open loop [0].
Remote-operated control and open loop [2] funct ions
in the same way as Local control and ope n loop
[1]; however, the frequency converter can also
be controlled via the digital inputs.
Local co ntrol as parameter 100 [3] is used when
the motor speed is to be set via parameter
003 Local reference,butw
ithout 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 ca n 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 o f rotation will be maintained. If the present
direction of rotation does not respond to the reversing
signal (negative reference), the referenc
ewillbesetto0.
Shifting from Local operation to Remot
eoperation
in parameter 002 Local/remote control, w hile
this parameter has been set to Remote-operated
control and open loop [1]: The config
uration
selected in parameter 100 Configuration will be
active. The shift will be smooth.
