User Manual of A90 Series Inverter For a variety of complex scenes, two sets of PID parameters have been introduced into the process PID module. Switching or linear interpolation of the two sets of parameters can be performed according to the function setting (F09.11) and input conditions (e.g. input function “43: PID parameter switching”, and deviation e(k)). See the instruction Table 7-13 for details. Table 7-13 Description of PID Parameter Options As described in the table, when the function code F09.11 is set to 0, the PID parameters will not be switched, and the first group of parameters (F09.05 to F09.07) will 202 F09.06 Integral time 1 0.000 to 30.000; 0.000:

The first group of parameters is used. 43:
PID parameter PID parameters are switched via the digital input terminal switching (43: PID parameter switching). 1 0 Invalid switching, the first group of parameters 1 Valid switching, the second group of parameters |e (k)| - F09.12/13 PID parameters are automatically switched according to the deviation. |e(k)| The first group of parameters 2 |e(k)| The second group of parameters Middle According to the deviation, linear interpolation is performed based on the two groups of parameters.
