5 Configuration
5.1.4 Setpoint value configuration
This setting determines which input specifies the setpoint value, how high the base
load is, and which alternative value should be applied in the event of an error.
Value/settings Description
Setpoint input Current input This setting specifies which analog input supplies the setpoint
value for the power output.
Note:
These inputs can also be used for logic operation.
v For switching level, see Chapter 10.7 "General char-
acteristic data"
Voltage input
Binary input1 Note:
This setting is only available if power controller
r
SCR control
r
Logic (switch) is set.
In this case, the power controller is controlled in the same way
as a solid-state relay (SSR) via binary input 1 or 2:
Contact: closed
r
100 % and open
r
0 %
(for control direction set ex works).
Binary input2
Via interface Means that the setpoint value for the power output is provided
via an interface.
α
input This setting is only available power controller
r
SCR control
r
Logic (switch) is set.
This setting specifies which signal the
α
default values should control or whether it
should be fixed.
The "
α
default values" value is a phase angle with which all sine waves are cut to limit
the power.
Not to be confused with the value for
α
start!
No input No phase angle is specified (full sine waves)
Voltage input or cur-
rent input This standard signal specifies the phase angle as shown in
the diagram.
Value, adjustable The phase angle is entered as "
α
default value".
Via interface The phase angle is set via an interface.
α
input value 0 to 180 °el This is the phase angle if "Value, adjustable" was set under
α
input value.
