Function chart number:

FP3300, FP3310

Analog to the fixed frequencies (refer to Section 3.7), the PID controller has
separate programmable PID fixed setpoints. The values are defined using
parameters P2201 – P2215 and are selected using binector inputs P2220 – P2223,
P2225, P2226. The selected PID fixed setpoint is available via connector output
r2224 where it can be further processed (e.g. as PID main setpoint

→ P2253 =

2224).
3 methods are available to select the PID fixed setpoints, analog to the fixed
frequencies (Section 3.7):
¾

Direct selection

¾

Direct selection + ON command

¾

Binary-coded selection + ON command

The methods are selected using parameters P2216 – P2219, P2225, P2227.

P0701 = 15
or
P0701 = 99, P2220 = 722.0, P2216 = 1
