The "Command pulse filter time constant" (FC-19) parameter for the pulse train input

circuit hardware can be selected by the command pulse frequency.

Lo 1 Less than 200k pulses/s

Hi (default setting) 0.2 More than 200k pulses/s

Note: When using phase difference two-phase pulse (A, B phase input), the

recommended input frequency is 1/4 of the frequency value in the above

table.

(2) Electronic gear

Position commands input by pulse train signals are processed in the electronic gear

and become the position command value. This electronic gear multiples the input

command value by (FA-12/FA-13) to form the position command value. That relation

is shown in the following formula.
