2-Axis Linear Interpolation Control - Mitsubishi Electric MELSEC iQ-F Series FX5 User Manual

2-axis linear interpolation control

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

■Operation chart
In the 2-axis linear interpolation control of the absolute system, specified two axes are used to implement linear interpolation
positioning from the current stop position (start point address) to the address set in [Da.6] Positioning address/movement

[Example]
If the start point address (current stop position) is (1000, 1000) and the end position address (positioning address) is (10000, 4000), positioning will be
implemented as described below.

■Restrictions
In the following case, an error occurs and the positioning will not start. During the positioning control, the operation stops
immediately at the detection of the error.
