Coordinates example
When the parameters are set as shown in the above table, the motor can be operated on coordinates in the figure.

If the Wrap setting (41C7h) or the Initial coordinate generation & wrap setting range (41C9h) is
changed, the absolute position may be shifted. When the parameter is changed, perform the position
preset (P-PRESET) or return-to-home operation.

Setting conditions of Initial coordinate generation & wrap setting range (41C9h)
When the wrap range satisfies the following conditions, continuous rotation in the same direction can be performed
while the home is maintained.
Condition 1
1,800 *
Wrap setting range
= To be an integer
Condition 2
Electronic gear B
Electronic gear A
Wrap setting range × Resolution = Wrap setting range × × 10,000
* The motors of frame size 20 mm (0.79 in.)
and 28 mm (1.10 in.) are 900.
= To be an integer
If the setting conditions of the Initial coordinate generation & wrap setting range (41C9h) is not
satisfied even when the Wrap setting (41C7h) is set to "1: Enable,” information of the Wrap setting
error will be generated. If the main power supply and the control power supply are turned on again
or Configuration is executed in a state where information of the Wrap setting error is generated, an
alarm of the Wrap setting error will be generated.
Setting example 1
•
Wrap setting range: 100 rev
• Resolution: 10,000 P/R (electronic gear A=1, electronic gear B=1)
•
Motor: Standard motor (gear ratio 1)

1
Wrap setting range × × 10,000 = 100 × × 10,000 = 1,000,000
The setting conditions are satisfied since both the conditions (1) and (2) are integers. The wrap function can be used.
