5.6 Linear Interpolation Control
5.6.1 Overview
The interpolation control is available under the following conditions.
■
Combinations of interpolation control
Model
Interpolation axis 1 Interpolation axis 2 Interpolation axis 3
X-axis Y-axis X-axis Y-axis X-axis Y-axis
Transistor output type
C14T CH0 CH1 - -
C30T CH0 CH1 CH2 CH3 -
C60T CH0 CH1 CH2 CH3 CH4 CH5
Relay output type
(When using the pulse
I/O cassette)
C14R - - -
C30R CH0 CH1 - -
C60R CH0 CH1 - -
(Note 1) In case of the relay output type Control Unit, two pulse I/O cassettes are required.

Conditions of interpolation control
Item
Condition under which interpolation control is executable
Available Not available
Operation pattern
E-point control
P-point control + E-point control
C-point control + E-point control
JOG operation
Home return
(Note 1)
J-point control
Control method Increment mode, Absolute mode -
Dwell time setting Set the E-point control to 1 ms or more.
When set to 0 ms, the positioning error
occurs.
(Note 1) In the home return operation, the home return start instruction (F382 ORGST) is executed for each
channel corresponding to X and Y axes. The trajectory is not linear interpolation.
■
Setting method of speed
Item Composite speed Long axis
Operation
Setting method
Specify the speed combining the speed
of X and Y axes.
Specify the speed for the axis whose
movement amount is large.
(Note 1) When specifying the same value, the long axis speed is faster than the composite speed.
