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

Operation chart

MELSEC-Q

In incremental system 2-axis linear interpolation control, addresses established by a machine OPR on a 2-axis coordinate plane 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.

Example

When the axis 1 movement amount is 9000 and the axis 2 movement amount is -3000, positioning is carried out as follows.
