Coordinates management
„ 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 revolutions and the resolution is 10,000 P/R
Wrap range o set ratio=0.00 %
Wrap range o set ratio=25.00 %
Wrap range o set ratio=50.00 %
Wrap range o set ratio=75.00 %
Wrap range o set ratio=100.00 %
z Wrap range offset value setting
The coordinates can be shifted in a step unit for the coordinate system having offset with the Initial coordinate
generation & wrap range offset ratio (41CBh).
When the coordinates are set with the Initial coordinate generation & wrap range offset value
(41CCh), information of Wrap setting error is generated if the home is not included in the coordinates.
If the control power supply is turned on again or Configuration is executed in a state where
information of Wrap setting error is generated, an alarm of Wrap setting error will be generated.
Setting example 1:
When the wrap range is 1,800 revolutions, the resolution is 10,000 P/R, and the wrap offset ratio
setting is 50 %.
Wrap o set value=0 step
Wrap o set value=1,000 steps
Wrap o set value=−1,000 steps
Setting example 2:
When the wrap range is 1,800 revolutions, the resolution is 10,000 P/R, and the wrap offset ratio
setting is 0 %.
Wrap o set value=0 step
Wrap o set value=1,000 steps*
Wrap o set value=−1,000 steps
