Setting example 2
• Wrap setting range: 14.4 rev
• Resolution: 3,333.333... P/R (electronic gear A=3, electronic gear B=1)
• Motor: TS geared motor (gear ratio 3.6)

Wrap setting range × × 10,000 = 48,000
The setting conditions are satisfied since both the conditions (1) and (2) are integers. The wrap function can be used.
Setting example 3
• Wrap setting range: 4.5 rev
• Resolution: 10,000 P/R (electronic gear A=1, electronic gear B=1)
• Actuator:

1
Wrap setting range × × 10,000 = 4.5 × × 10,000 = 45,000
The setting conditions are satisfied since both the conditions (1) and (2) are integers. In the case of this setting, the
wrap function is executed every time the motor rotates by 90 degrees on the output shaft of
DGII Series.
Setting example 4
• Wrap setting range: 1,000 rev
•
Resolution: 10,000 P/R (electronic gear A=1, electronic gear B=1)
• Motor: PS geared motor (gear ratio 20)

Condition 2 Wrap setting range × Resolution = 1,000 × 10,000 = 10,000,000
The setting conditions are not satisfied since the condition (1) is not an integer. Information of Wrap setting error is
generated and the wrap function cannot be executed.
„
Wrap offset function
The position of the boundary point of the wrap range can be offset by using the mechanical home as a reference. The
wrap offset is set with the Initial coordinate generation & wrap range offset ratio (41CBh) and the Initial coordinate
generation & wrap range offset value (41CCh).
z
Wrap offset ratio setting
When the Initial coordinate generation & wrap range offset ratio (41CBh) is set, the wrap range can be offset in the
negative direction.
Setting example: When the wrap range is 1,800 rev and the resolution is 10,000 P/R
Wrap range offset ratio = 0.00 %
Wrap range offset ratio = 25.00 %
Wrap range offset ratio = 50.00 %
Wrap range offset ratio = 75.00 %
Wrap range offset ratio = 100.00 %
