[Basic setting]
Division and
multiplication of encoder
pulse
output(Numerator /
Denominator )
Set the division and multiplication of encoder pulse output.
When the 1-roration pulse number of encoder and the motor is different, set it
to ‘Numerator / Denominator =1-roration pulse number of encoder/ 1-roration
pulse number of motor.
If the output Z-phase pulse width is narrow and the upper control device
cannot identify it correctly, we can reduce the division and multiplication ratio
or speed to increase the pulse width by encoder pulse output division and
multiplication No. 276. 0 and 278. 0.
[Pulse width]= 1/ rotation speed (division/ multiplication ratio × 217)
[Initial value] (Numerator )/ (Denominator )=1000/8000
[Setting range] (Numerator ) 1～65535；(Denominator )1～65535
Frequency division/multiplication could be set to 1/32768 to 1.
But it’s necessary that [encoder resolution] × [Frequency
division/multiplication] = [multiples of 4] and output frequency must less than
4Mpps(Maximum value).

Analog torque command
input filter (Denominator
/Numerator)
This parameter is for the low-pass filter that smooths analog torque command
input. It's valid when No.302.1 =1(enable).
When the value is small, the smoothing becomes stronger, but the traceability
to command drops.
When the value is bigger, the traceability to command improves, but it is easy
to be disturbed.
Numerator / Denominator cannot exceed “1”.
If Numerator / Denominator=1, no filtering.
[Initial value] Numerator / Denominator= 16000/65535
[Setting range] 0 to 65535/1 to 65535
[Adjustment]
Analog torque command
input gain (Denominator
/Numerator)
Set Analog torque command input gain.
Input of Analog command voltage =-10V or +10V with
(Numerator)/(Denominator)=1 attains motor peaks torque.
Motor rotation direction differs according to the selection of analog command
voltage symbols and characteristics.
※For the details of peaks torque, refer to [Basic specification].
[Initial value] (Numerator) / (Denominator) = 3100/3100 (Varies with different
motor models)
[Setting range] 0 to 65535/1 to 65535
