PID REGULATOR
Block diagram
The function is activated by assigning an analog input to the PID feedback (measurement).
(1) Ramp AC2 is only active when the PID function starts up and during PID "wake-ups".
PID feedback:
The PID feedback must be assigned to one of the analog inputs AI1 to AI3, to the pulse input, according to
whether any extension cards have been inserted.
PID reference:
The PID reference must be assigned to the following parameters: Preset references via logic inputs (rP2,
rP3, rP4)
In accordance with the configuration of [Act. internal PID ref.] (PII) page 196
:
Internal reference (rPI) or
Reference A ([Ref.1 channel] (Fr1) or [Ref.1B channel] (Fr1b), see page 139
).
Combination table for preset PID references:
A predictive speed reference can be used to initialize the speed on restarting the process.
