PNO Parameter Descriptions
1931
PID Output Filter TC
In order to help attenuate high frequency noise on the PID output, a first order output filter has been provided. This parameter
determines the output filter time constant.
1932
PID Output Pos Limit
The maximum positive excursion (limit) of the PID output.
1933
PID Output Neg Limit
The maximum negative excursion (limit) of the PID output.
1934
PID Output Scaling
The overall scaling factor which is applied after the positive and negative limit clamps
1935
