6-5 Encoder Dividing Function
Outline of Operation
The number of pulses can be set for the encoder signals output from the driver.
You can set the number of pulses per motor rotation in the range of 1 to (the number of encoder
resolution pulses).
This function is enabled in the following cases:
• When you use a controller with a low response frequency
• When you want to set the pulse rate to a simple value
Example: Set the encoder dividing ratio to 2,000 (pulses/rotation) for when the
resolution is set to 5
μ
m/pulse on mechanical systems that travel 10 mm per
motor rotation.

Explanation
Reference
Pn011
Encoder Dividing
Numerator
Set the number of phase-A and phase-B output
pulses, respectively per motor rotation.
Pn012
Encoder Output
Direction Switching
Selection
Select the phase B logic for pulse regeneration
output and the output source.
Pn503
Encoder Dividing
Denominator
Set the denominator when the number of pulses
per motor rotation in pulse regeneration is not an
integer.
Pn533
Pulse Regeneration
Output Limit Setting
Set whether to enable or disable the detection of
Err28.0 "pulse regeneration error."
0: Disabled, 1: Enabled
Pn620
External Scale Phase-
Z Setting
Set the external scale phase-Z output width.
Pn621
Serial Absolute External
Scale Phase-Z Setting
Set the phase-Z regeneration position when the
serial absolute external scale is used.
0: Phase-Z output only at a position where the
absolute position is 0
1 to 228: After a phase-Z output at the position
where the absolute position is 0, phase Z
is output in the set value pulse cycle.
Pn622
Phase AB External
Scale Pulse Output
Method Selection
Select the regeneration method of pulse outputs
OA and OB when an external scale of phase AB-
output type is used.
0: Without signal regeneration
1: With signal regeneration
