Parameter setting

Terminal control
You can change to other parameter sets via e.g. the digital inputs X5/E1 ... X5/E5.
After mains connection the controller reads parameter set 1 first. Then, the terminals are evaluated
and the desired parameter set is loaded. A LOW-HIGH edge at input DCTRL-PAR-LOAD (” Load
parameter set” ) is not necessary in this case:
•
One or two digital inputs must be assigned to ” Select parameter set” in every parameter set.
– Determine the source(s) for ” Select parameter set” under C0880. The signal names are:
DCTRL-PAR*1 and DCTRL-PAR*2.
•
One digital input must be assigned to ” Load parameter set” in every parameter set:
– Determine the source for ” Load parameter set” under C0881.The signal name is:
DCTRL-PAR-LOAD.
•
These inputs must have the same assignment in all parameter sets which you want to use.
•
The controller reads the terminals assigned with ” Select parameter” as a binary code. The
input DCTRL-PAR*1 is the first input, the input DCTRL-PAR*2 is the second input (e.g. E1 =
first input, E2 = second input).
– The signal must be applied constantly at the terminals for at least 10 ms so that the
parameter set to be loaded is recognized correctly.
– Terminal signals to select parameter sets:
1st input (DCTRL-PAR*1) 2nd input (DCTRL-PAR*2)
Parameter set 1 LOW LOW
Parameter set 2 HIGH LOW
Parameter set 3 LOW HIGH
Parameter set 4 HIGH HIGH
•
A LOW-HIGH edge at the input ” Load parameter set” DCTRL-PAR-LOAD changes to the new
parameter set.
Procedure:
1. Trigger digital inputs, which are assigned to the function ” Select parameter set” .
2. Inhibit controller with X5/28 = LOW.
3. Trigger LOW-HIGH edge at the input ” Load parameter set” .
4. When the loading is completed:
– C0002 displays the number of the loaded parameter set.
– RDY is illuminated.
5. Enable controller with X5/28 = HIGH.
