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.

(When user
constant Cn-12 is
set to 0)
t3 ≥ 40 ms
PG pulse
t4, t5, t6 ≤ 2ms
t7 ≥ 20 μs
Note 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.
The error counter clear (CLR) signal must be ON for at least 20 μs. Otherwise, it be-
comes invalid.
