2 Axes Linear Interpolation Control
Linear interpolation control from the current stop position with the specified 2 axes is executed.
ABS-2 (Absolute data method) and INC-2 (Incremental data method) servo instructions are used in the 2 axes linear
interpolation control.
: Must be set,
: Set if required
*1 Only when the reference axis speed is specified
Processing details
■
Control using ABS-2 (Absolute data method)
• 2 axes linear interpolation from the current stop address (X
1
or Y
1
) based on the home position to the specified address (X
2
or Y
2
) is executed.
• The travel direction is set by the stop address (starting address) and positioning address of each axis.
Ex.
When the current stop address is (1000, 4000), and the positioning address is (10000, 2000).
