tion.
Communication option card warning [Hex]
gives a warning word if there
is a fault in the communication bus. Only active if communication options
are installed.
If there are no communication options 0 Hex is displayed.

Small display line 1.1
Value:
See par. 009
Large display readout
Analog input 53 [V] [17]
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 gives a view of
process reactions to reference changes. The display readout is activated
by pushing the [DISPLAY STATUS] key.

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 via
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
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 adjustable frequency drive
can also be controlled 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 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 adjustable frequency
drive can also be controlled via the digital inputs.
