3-axis linear interpolation control (INC linear 3)
■Operation chart
In the incremental system 3-axis linear interpolation control, the designated 3 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 the
"[Da.6] Positioning address/movement amount". The movement direction is determined the sign of the movement amount.
• Positive movement amount: Positioning control to forward direction (Address increase direction)
• Negative movement amount: Positioning control to reverse direction (Address decrease direction)
When the axis 1 movement amount is 10000, the axis 2 movement amount is 5000 and the axis 3 movement amount is 6000,
positioning is carried out as follows.
■Restrictions
An error will occur and the positioning will not start in the following cases. The machine will immediately stop if the error is
detected during a positioning operation.
• If the movement amount of each axis exceeds "1073741824 (= 2
30
)" when "0: Composite speed" is set in "[Pr.20]
Interpolation speed designation method", the error "Outside linear movement amount range" (error code: 1A15H, 1A16H)
occurs at a positioning start. (The maximum movement amount that can be set in "[Da.6] Positioning address/movement
amount" is "1073741824 (= 2
30
)".)
