• P2350 = 4
This tuning only changes values of P and I and should be a quarter damped response.
The option to be selected depends on the application but broadly speaking option 1 will give a good
response, whereas if a faster response is desired option 2 should be selected.
If no overshoot is desired then option 3 is the choice. For cases where no D term is wanted then option 4
can be selected.
The tuning procedure is the same for all options. It is just the calculation of P and D values that is different.
After autotune this parameter is set to zero (autotune completed).
P2354 PID tuning timeout
length [s]
60 - 65000 240 U, T - - U16 3
This parameter determines the time that the autotuning code will wait before aborting a tuning run if no
oscillation has been obtained.
P2355 PID tuning offset [%] 0.00 -
20.00
5.00 U, T - - Float 3
Sets applied offset and deviation for PID autotuning.
Note: This can be varied depending on plant conditions e.g. a very long system time constant might require a
larger value.
P2360[0...2] Enable cavitation
protection
0 - 2 0 U, T - DDS U16 2
Cavitation protection enabled.
Will generate a fault / warning when cavitation conditions are deemed to be present.
