6.12.2 PID Setpoint
Value
This section describes the PID-controller setpoint value. PID-setpoint value is
composed of the absolute reference value (cn.1) and an additional setpoint source
which is adjustable with cn.0. The two values are added up and transferred to the PID-
controller setpoint input.
Pic. 6.12.2
PID controller set value
PID absolute reference
(cn.1)
With cn.1 the set value of the PID-Controller is preset digitally in the range of
-400,0...400,0%. The parameter is set-programmable.
PID reference source
(cn.0)
Parameter cn.0 specifies the input which supplies the additional setpoint value. Following
possiblities are selectable:
cn.0
PID reference source
0
off (default)
1
Analog input AN1 (ru.28)
2
Analog input AN2 (ru.30)
3
Analog input AN3 (ru.32)
4
Aux input (ru.53)
If one of the analog channels is adjusted, the signals can be individually adapted to
the requirements with the analog amplifier, as described in Chapter 6.2.
