No. 34.0
Pulse train command:
Ratio (numerator)
Range Default Characteristics
1 to 65,535
1,000

No. 36.0
Pulse train command:
Ratio (denominator)
1 to 65,535
Function
Use
Use these two parameters to set the multiplier and divider for the position command
pulse.
When the pulse count per rotation of host command is not equal to its counterpart of motor, select
one of the following for (numerator)/(denominator).
（numerator）=（motor pulse count per rotation）/4=32,768
（denominator）=（host command pulse count per rotatio）/4
=
motor pulse count per rotation / 4
host command pulse count per rotatio / 4
=

*) 131,072 is the pulse count per rotation of the motor.
The default setting values are assumed 131072 pulses of the host command pulse number per a
rotation.
Remark
Range of Pulse Ratio (numerator/denominator)
・Pulse train command: x0.001 to x1,000
・Internal Position Command: x1 to x1,000

No. 48.0
Analog velocity:
Input filter (numerator)
Range Default Characteristics
0 to 65,535 16,000
No. 49.0
Analog velocity:
Input filter (denominator)
1 to 65,535 65,535
Function
Use
These two parameters are used to configure a low-pass filter, which suppresses
the noise component of analog velocity command input.
Setting Noise Resistance Command Response
small strong slow
large weak fast
Prerequisite Analog Velocity: Input filter switch (No.62.1) = 1 (Enable)
Remark
The ratio of No.288.0 (numerator) to No.289.0 (denominator) must not be higher than 1.
If the ratio = 1, filtering will not take effect.
