[Initial value] 0 (Incremental system)
[Setting range] 0 to 2
272.1r [Basic setting]
Encoder output
rotation direction
Set the rotation direction of encoder output.
0 = Down counting in the case of CCW rotation
1 = Up counting in the case of CCW rotation
[Initial value] 1 (Up counting in the case of CCW rotation)
[Setting range] 0 or 1
Yes

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

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).

[Adjustment]
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
No

[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

[Basic setting]
Analog torque
command CCW
torque limit
Set Analog torque command CCW torque limit Override
Analog command CCW torque limit =motor peak torque × (Override
(Numerator)/Override(Denominator))
[Initial value] (Numerator) / (Denominator) = 3100/3100 (Varies with motor models)
No
