(Funcon list: PID-I inhibited)
•
Further seng opons: 4Trigger list ^ 64
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 No trigger assigned (trigger is constantly FALSE).

Funcon list: Acvate PID inuence ramp
(Funcon list: PID-Inf ramp on)
•
Further seng opons: 4Trigger list ^ 64
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).
1 Constant TRUE Trigger is constantly TRUE.
Example for operang mode
In the following example, the "Deacvate PID controller" funcon is used to deacvate the
PID control temporarily:
•
As standard setpoint source, the frequency preset 1 is set to 20 Hz.
•
The switch S1 starts the motor in the forward direcon of rotaon. The switch S1 in the
inial posion stops the motor again.
•
The switch S2 deacvates the PID control. The motor is then driven in a speed-controlled
way.
