14.13 Coordinate System for Rotary Axis
Function and purpose
The axis designated as the rotary axis with the parameters is controlled with the rotary axis'
coordinate system.
The rotary axis includes the rotating type (short-cut valid/invalid) and linear type (workpiece
coordinate position linear type, all coordinate position linear type).
The workpiece coordinate position range is 0 to 359.999° for the rotating type, and 0 to
±
99999.999° for the linear type.
The machine coordinate position and relative position differ according to the parameters.
The rotary axis is commanded with a degree (°) unit regardless of the inch or metric designation.
The rotary axis type can be set with the parameter “#8213 rotation axis type” for each axis.

ABS
command
The incremental
amount from the end
point to the current
position is divided by
360, and the axis
moves by the
remainder amount
according to the sign.
Moves with a
short-cut to the
end point.
In the same manner as the normal linear axis,
moves according to the sign by the amount
obtained by subtracting the current position from
the end point (without rounding up to 360
degrees).
INC command
Moves in the direction of the commanded sign by the commanded incremental amount
starting at the current position.
Until the intermediate point:
Depends on the absolute command or the incremental command.
Reference
position return From the intermediate point to the reference position:
Returns with movement within 360 degrees.
Moves and returns in the
reference position direction
by the difference from the
intermediate point to the
reference position.
