Factory setting
p2350
Enable PID autotuning
Automatic controller setting based on the "Ziegler Nichols"
method.
After completion of the autotuning, the converter sets
p2350 = 0.
0: No function
1: The process variable follows the setpoint after a sudden
setpoint change (step function) relatively quickly, however
with an overshoot.
W
2: Faster controller setting than for p2350 = 1 with larger
overshoot of the controlled variable.
W
3: Slower controller setting than for p2350 = 1. Overshoot of
the controlled variable is, to a large extent, avoided.
W
4: Controller setting after completion of the autotuning as for
p2350 = 1. Optimize only the P and I action of the PID con‐
troller.
