Input Pulse Multiply Function:
When the reference form is two-phase pulse train
with 90° phase difference, the input pulse multiply
function can be used.
The electronic gear function can also be used to
convert input pulses.

Note (1) The interval from the time the Servo ON signal is turned ON until a reference pulse is
input must be at least 40 ms. Otherwise, the reference pulse may not be input.
