32 TABLE OPERATION
32.2 Operations of Control Method
• This table cannot be specified for continuous operation. When a table with this control method is executed in continuous
operation, the operation is decelerated to a stop.
• When the specification method for the interpolation speed is [Reference-axis speed], set the axis with the longer positioning
address as the reference axis. If the axis with the shorter positioning address is set as the reference axis, the speed of the
longer axis may exceed the maximum speed and interpolation operation cannot be performed properly.
• When such as forward limit or reverse limit, is detected in either of the reference axis or counterpart axis during
interpolation operation, both the axes are decelerated to a stop.
• Do not change the value of operand 4.
• This function is not intended for purposes where high precision path is required because each axis is only started
simultaneously.
Using the following or similar set values, in particular, may lead to a larger difference in stop time between each axis. Even
when there is a difference in stop time, operation stops at the correct position.
1. When there is a large difference in transfer distance between the reference axis and counterpart axis
2. When the speed of the reference axis or counterpart axis is equal to or lower than the bias speed or exceeds the
maximum speed
3. When the speeds of the reference axis and counterpart axis are extremely slow
4. When an extremely long acceleration time or deceleration time is set
If interpolation operation is aborted, the stop position of each axis may be off the straight line.
