Division/ multiplication
(Numerator /
Denominator )
Set the parameters of position command pulse division/ multiplication.
When the number of upper command pulse and motor pulse per revolution is
different, calculate in terms of [(Numerator) / (Denominator )=(Number of
pulse per servo motor revolution) / (Number of host command pulse per
revolution)
[Setting example]
The number of pulse per motor revolution is 131072[pulse/rev]. Numerator can
be set 32768 by a quarter of 131072. Denominator can be set by a quarter of
the number of upper command per revolution. The corresponding parameter
setting of the number of upper command pulse per revolution is as follows.

Analog command input
Filter parameter
(Numerator /
Denominator )
Low-pass filter parameter for smoothing analog speed command input.
It is valid when input filter selection (No.062.1) is set “1”,.
Parameter decrease→Smoothing effect becomes stronger, command
traceability reduces.
Parameter increase→command traceability increases,， susceptible to
interference
(Numerator / Denominator ) the value must be less than 1.
(Numerator / Denominator ) =1, filter invalid

Analog command input
Gain
(Numerator /
Denominator )
Gain of analog speed command input.
When (Numerator) / (Denominator )=1 and ±10V analog command voltage is
input, the highest rotation speed of motor can be reached.
※As for the highest rotation speed of motor, refer to 「Basic specification」
According to different choice of symbol and polarity for analog command
voltage, the rotation direction of motor is different.
Decreasing this value has the effect of decreasing proportional gain of position
