14.10 Process controller funcon selecon
By means of the following funcons, the response of the inverter can be controlled when PID
control is acvated. 4Conguring the process controller ^ 407
Parameter Name / value range / [default seng] Info
0x2631:045

Funcon list: Deacvate PID controller
(Funcon list: PID o)
•
For further possible sengs, see parameter
0x2631:001 (P400.01). ^ 532
Assignment of a trigger for the "Deacvate PID controller" funcon.
Trigger = TRUE: If PID control is acvated, ignore PID control and drive
the motor in speed-controlled manner.
Trigger = FALSE: If PID control is acvated, drive the motor with PID con-
trol.
Notes:
•
The PID control mode can be selected in 0x4020:001 (P600.01).
0 Not connected
0x2631:046

Funcon list: Set process controller output to 0
(Funcon list: PID output=0)
•
For further possible sengs, see parameter
0x2631:001 (P400.01). ^ 532
Assignment of a trigger for the "Set process controller output to 0" func-
on.
Trigger = TRUE: If PID control is acvated, I component and the output of
the PID controller are set to 0 and the internal control algorithm is stop-
ped. The PID control remains acve.
Trigger = FALSE: no acon / deacvate funcon again.
0 Not connected
0x2631:047

Funcon list: Inhibit process controller I-component
(Funcon list: PID-I inhibited)
•
For further possible sengs, see parameter
0x2631:001 (P400.01). ^ 532
Assignment of a trigger for the "Inhibit process controller I-component"
funcon.
Trigger = TRUE: If PID control is acvated, the I component of the PID
controller is set to 0 and the integraon process is stopped.
Trigger = FALSE: no acon / deacvate funcon again.
Notes:
•
The reset me can be set in 0x4049 (P602.00).
0 Not connected
0x2631:048

Funcon list: Acvate PID inuence ramp
(Funcon list: PID-Inf ramp on)
•
For further possible sengs, see parameter
0x2631:001 (P400.01). ^ 532
Assignment of a trigger for the "Acvate PID inuence ramp" funcon.
Trigger = TRUE: the inuence of the process controller is shown via a
ramp.
Trigger = FALSE or not connected: the inuence of the process controller
is hidden via ramp.
Notes:
•
The inuence of the process controller is always acve (not only when
PID control is acvated).
•
Acceleraon me for showing the inuence of the process controller
can be set in 0x404C:001 (P607.01).
•
Deceleraon me for hiding the inuence of the process controller
can be set in 0x404C:002 (P607.02).

Process controller setup (PID): Operang mode

Selecon of the process controller operang mode.
0 Inhibited Process controller deacvated.
1 Normal operaon The setpoint is higher than the fed back variable (actual value). If the sys-
tem deviaon increases, the motor speed is increased.
Example: pressure-controlled booster pumps (increase in the motor
speed produces an increase in pressure.)
2 Reverse operaon The setpoint is lower than the fed back variable (actual value). If the sys-
tem deviaon increases, the motor speed is increased.
Example: temperature-controlled cooling water pump (increase in motor
speed produces decrease in temperature.)
3 Normal bi-dreconal The direcon of rotaon corresponds to the sign of the system devia-
on. If the system deviaon increases, the motor speed is increased.
4 Reverse bi-direconal A negave system deviaon causes a posive direcon of rotaon. If the
system deviaon increases, the motor speed is increased.

Reset me for system deviaon.
•
With the seng "6000 ms", the I component is deacvated.
•
The I component can also be deacvated via the "Inhibit process con-
troller I-component" 0x2631:047 (P400.47) funcon.

If the trigger assigned in 0x2631:048 (P400.48) of the "Acvate PID inu-
ence ramp" funcon is TRUE, the inuence of the process controller is
shown by means of a ramp with the acceleraon me set here.

PID inuence: Deceleraon me for masking out

If the trigger assigned in 0x2631:048 (P400.48) of the "Acvate PID inu-
ence ramp" funcon is FALSE, the inuence of the process controller is
hidden via a ramp with the deceleraon me set here.
