2-Axis Linear Interpolation Control (Inc Linear 2) - Mitsubishi Electric QD77MS User Manual

[2] 2-axis linear interpolation control (INC linear 2)

Operation chart
In incremental system 2-axis linear interpolation control, the designated 2 axes are
used. Linear interpolation positioning is carried out from the current stop position
(start point address) to a position at the end of the movement amount set in "[Da.6]
Positioning address/movement amount". The movement direction is determined by
the sign of the movement amount.
• Positive movement amount .............. Positioning control to forward direction
• Negative movement amount ............. Positioning control to reverse direction

Example
When the axis 1 movement amount is 9000 and the axis 2 movement amount is -3000, positioning
address (10000, 4000) is carried out as follows.
