Description
The SINAMICS G120 has an integrated technology controller (PID controller, enabled
through P2200). This can be used to process basic higher-level closed-loop control
functions. These typically include:
● Closed-loop pressure control for extruders
● Closed-loop water level control for pump motors
● Closed-loop temperature control for fan motors
● Closed-loop dancer roll position control for winder applications
● And similar control tasks
The technology controller setpoints and actual values can be entered using the PID
motorized potentiometer (PID-MOP), PID fixed setpoint (PID-FF), analog inputs (AI) or
through the serial interface as shown in the figure below. The appropriate parameterization
of the BICO parameter defines which setpoints or actual values are to be used.
