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 Fig. 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.
P4.16 PG Pulse Range
Range: 1～9999【1024】
Note:
◆The setting value of P4.16 (Number of pulses per revolution of PG) is determined by
the characteristic parameters of PG.
