Process controller setpoint = C0181
C0145 = 1
Process controller setpoint = Value under C0181.
·
Applications are e.g. dancer controls, pressure controls and flow rate controls
·
Activate the automatic DC−injection brake (auto DCB) with C0019 = 0 or C0106 = 0
·
C0181 is the same in all parameter sets.
C0145 = 2
Process controller setpoint = Freely configured signal via C0412/4.
·
The process controller setpoint (PCTRL1−SET1) must be linked with an analog input signal
under C0412/4.
·
Use C0138 to display the current process controller setpoint.
·
The setpoint acts directly on the process controller.
)
Note!
If you do not link an analog input signal with the process controller setpoint under
C0412/4, the process controller setpoint can be directly selected under C0138.
7.8.3 Actual value selection for the process controller
Description
The actual value is the process feedback signal (e.g. from a pressure encoder or a speed encoder).

Activation
The actual process controller value (PCTRL1−ACT) must be linked with an analog input signal under
C0412/5.
Use C0051 to display the current actual process controller value.

Note!
If you do not link an analog input signal with the actual process controller value
under C0412/5, the actual process controller value can be directly selected under
C0051.
