*1 Counting speed setting can be done using the parameter setting. (
*2 Note that the count may be done incorrectly by inputting pulses whose phase difference is small between the phase A
pulse and phase B pulse. To check the input waveform of the phase A pulse and phase B pulse, or to check phase
difference between the phase A pulse and phase B pulse, refer to the following:
Page 30, Section 3.2.1
*3 The counting speed is affected by the pulse rise/fall time. The applicable counting speed is listed below.
Note that the count may be done incorrectly by counting pulses with long rise/fall time.
