Note 2:

When P4.00 is set to 1, 2, or 3, the function of P4.01~P4.04, P4.06~P4.09 and P4.11~P4.14 are combined for
one physical value, which is different to Note 1. User can define their own nonlinear curves by setting these
parameters. Six points can be set on the curve. As shown in Figure. 5-4-2. In addition, the setting value to
P4.01, P4.03, P4.06, P4.08, P4.11, P4.13 must increase in order.

Note 3:

The input filter time constant is used for digital filter of the input signal, in order to avoid interference of the
system.

The bigger the filter time constant, the higher the immunity level and the longer the response time is. On the
contrary, the smaller the time constant, the shorter the response time and the lower the immunity level is. If
the best setting is not clear, you can adjust setting value according to the status of control stability and
response delay time.
