6-5 Encoder Dividing Function
Outline of Operation
 The number of output pulses from the driver can be adjusted.
 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 used in the following cases:
- When you use a controller with a low response frequency
- When you want to set the pulse rate corresponding to a certain value
Example: Set the encoder dividing ratio to 2,000 (pulses/rotation) for when the
resolution is set to 5 μm/pulse on mechanical systems that travel 10 mm per
motor rotation.

P.8-46
Pn533
Pulse Regeneration
Output Limit Setting
Set whether to enable or disable the detection of
Err28.0 "pulse regeneration error."
0: Disabled, 1: Enabled
P.8-58
Pn620
External Scale Phase-
Z Setting
Set the external scale phase-Z output width.
P.8-61
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 2
28
: After a phase-Z output at the position
where the absolute position is 0, phase Z
is output every the set value pulse cycle.
No phase-Z is output until passing absolute
position 0

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. Z-out is directly Z-
in in the scale
1: With signal regeneration
