These above function codes defined input range of analog input voltage channel AI1, AI2, and the corresponding physical
quantity percentage and filtering time constant. AI1 can be chosen as voltage/current input via J1 wire jumper, and the
digital setting can be based on the relation of 0
～
20mA in accordance with 0
～
10V. The specific setting should be
depended on the actual condition of input signal.
AI1, AI2 input filtering time constant are used for filtering process of analog input signal, thus eliminating the disturbing
influence. The greater of the time constant, the better of the anti-interference ability, and the steadier of the control,
but the slower of the response; otherwise, the smaller of the time constant, the faster of the response, but the weaker
of the anti-interference ability, and the control may not be steady. If the optimum value can’t be decided in practical
