C0145 = 1
Process controller setpoint = Value under C0181.
l Applications are e.g. dancer controls, pressure controls and flow rate
controls
l Activate the automatic DC-injection brake (auto DCB) with C0019 = 0 or
C0106 = 0
l C0181 is the same in all parameter sets.
C0145 = 2
Process controller setpoint = Freely configured signal via C0412/4.
l The process controller setpoint (PCTRL1-SET1) must be linked with an
analog input signal under C0412/4.
l Use C0138 to display the current process controller setpoint.
l 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 C0051.
10.10.3 Actual value selection for the process controller
The actual value is the process feedback signal (e.g. from a pressure encoder or
a speed encoder).

Operation without process controller
(C0238 = 2):
• Display only: Output frequency with slip
compensation (MCTRL1-NOUT+SLIP)
Operation with process controller
(C0238 = 0, 1):
• Selection, if C0412/5 = FIXED-FREE
(not assigned)
• Displa y if C0412/5 is linked with a signal
