Functions used
-
Internal PID controller for pressure control.
- Regular control, setpoint selection via fieldbus with feedback via analog
channel terminal 8.
-
Networking via fieldbus (e.g. via plug-in module 2102).
-
Manual/remote changeover (H/Re).
- Setpoint selection change via key ( E1 = DOWN / E2 = UP).
-
Process setpoint selection (e.g. pressure [p]) via inverter JOG value.
-
Electrical controller inhibit (Ctrl. enable).

-
Set the rated motor data under C088 (rated motor current) and C091 (motor cos
j) depending on the motor
connected.
-
In addition to the setpoint input via fieldbus, the pressure setpoint can also be selected via the 8201BB keypad
(installation up to max. 10 m away from the controller) or via an analog input signal (using the 8274 plug-in
module).
Note!
-
For more detailed information on the process controller see chapter 7.5.10.
-
Calibration of the setpoints and actual values to the application datum under
C500 and C501.
(See chapter 5.4.2.4).
