4-Axis Linear Interpolation Control - Mitsubishi Electric MELSEC iQ-R-RD75P4 User Manual

4-axis linear interpolation control

In the 4-axis linear interpolation control ([Da.2] Control method = ABS linear 4, INC linear 4), four motors are used to perform
the position control in a linear path while the interpolation is performed for the axis directions set in each axis.
For details on the interpolation control, refer to the following.

4-axis linear interpolation control (ABS linear 4)
In the 4-axis linear interpolation control of the absolute system, four axes are used to perform the linear interpolation
positioning from the current stop position (start point address) to the address set in [Da.6] Positioning address/movement
amount (end point address).
■Positioning data to be set
To use the 4-axis linear interpolation control (ABS linear 4), set the following positioning data.
: Always set, : Set as required, : Setting not required
Setting item
[Da.1] Operation pattern
[Da.2] Control method
[Da.3] Acceleration time No.
[Da.4] Deceleration time No.
[Da.5] Axis to be interpolated
[Da.6] Positioning address/movement amount
[Da.7] Arc address
[Da.8] Command speed
[Da.9] Dwell time
[Da.10] M code
[Da.27] M code ON signal output timing
[Da.28] ABS direction in degrees
[Da.29] Interpolation speed specification method
For details on the settings, refer to the following.
Page 420 Positioning Data
• For the 4-axis linear interpolation control, set Reference axis speed and set the major axis as the reference
axis. If the minor axis is set as the reference axis, the speed of the major axis cannot be suppressed with
[Pr.8] Speed limit value.
• For the combinations of the reference axis and interpolation axes, refer to the following.
