11.5 Multi-axis Operation
This section explains multi-axis operations such as linear interpolation and circular interpolation.
11.5.1 Overview of Interpolation Control
Interpolation control is an operation that controls the loci of multiple axes by interlocking them.
The GM1 controller supports the following interpolation controls.

Absolute coordinates
Relative: Value relative to the
current value
Absolute: Coordinates based
on the machine zero point

Circular
interpolation
Center point
specification
Circular interpolation by
specifying a center point
Configuration parameters
Circular interpolation plane
(XY
, YZ, ZX)
Target coordinates (X, Y, X),
center point (I, J, K)
Velocity (F), acceleration /
deceleration (E)
Radius
Circular interpolation based on
the current value, target
coordinates, and radius
Configuration parameters
Circular interpolation plane
(XY
, YZ, ZX)
Target coordinates (X, Y, X),
radius (R)
Velocity (F), acceleration /
deceleration (E)
Helical interpolation
Circular interpolation + Helical
axis
Same as circular interpolation
(Center point and radius can
be specified)
Other
movements
Dwell time
Specifying the waiting time
between set movements
C-point control
Causing the axis to stop upon
completion of one movement
and then start next movement
This function can be executed
by inserting dwell time (0 ms)
or specifying parameters of
PMC_Interpolator2D or
PMC_Interpolator3D.
