3 MAJOR POSITIONING CONTROL
3.2 Positioning Data Setting
117
3
When the unit is set to Degree, the positioning range of the absolute system is 0 to 359.99999
. If the rotation
angle is 360
or larger in the circular interpolation control (x axis
y axis), the tangent control and normal line
control cannot be performed because 360
or larger angle cannot be set for the linear control (z axis: degree).
To perform the tangent control or normal line control with the rotation of 360
or larger angle, use the 3-axis
helical interpolation control (INC).
Error compensation of the circular interpolation control
In the 3-axis helical interpolation control, as well as the circular interpolation control (2 axes), [Pr.41] Allowable circular
interpolation error width is enabled. When a circular interpolation error occurs, the path of the circular interpolation control (X
axis
Y axis) becomes spiral as shown below.
Rotation direction when the line axis (Z axis) is set in degrees
When Degree is set to [Pr.1] Unit setting for the line axis, the rotation direction is determined depending on the axis control
data in [Cd.40] ABS direction in degrees of the reference axis. To set a rotation direction for each positioning data, set [Da.28]
ABS direction in degrees of each positioning data.
