Liner Interpolation Operation

→ For details on the related parameters, control data, and monitor data, refer to Section 9.12
1. Operation
Y axis
1) Set operation speed 1 of X-axis and target address 1 of X/Y-axis.
2) Select the linear interpolation operation from the operation pattern of X-axis and activate the START
command of X-axis. The linear interpolation operation shown above will be started at vector speed
(X-axis operation speed 1). (The positioning completion signal is turned OFF.)
The operation pattern and START command of Y-axis are ignored.
3) The work piece stops at the XY coordinate in target address 1, and the operation ends, turning the
positioning completion signal ON.
POINT
• The positioning completion signal turns ON if the travel distance is 0.
If the travel distance is 0 or the travel time is too short, however, it is impossible for the sequence program
to detect the positioning completion signal turning OFF.
• When interpolation operation is continued in table operation, it is continuous pass operation.
2. Operation speed
Actual operation speed (vector speed) is "X-axis operation speed 1 x X-axis override setting."
Operation speed 1 of X-axis can be changed using the operation speed change function except for operating
under the following conditions.
• During deceleration operation
• When the speed change disable during operation signal is ON.
3. Address specification
Absolute/relative address can be specified.
With the specified absolute address: Specifies a target address (position) using address 0 as the base.
With the specified relative address: Specifies a travel amount from the current address.
4. Rotation Direction
With the specified absolute address: The rotation direction depends on whether the target address 1 is
With the specified relative address: The rotation direction is decided by the sign (positive/negative) of target
