• For the sign, select the sign of position data.
• For the command method, select the absolute position command or incremental position command. For the absolute
position command, specify the distance from the home position. For the incremental position command, specify the
distance from the current position command.
• Position commands cannot be received until the completion of the home position return.
• For the operation method, select "individual", "continuous", or "loop operation using the point table selected at the start".
When continuous operation is selected, next point table is executed after a command has been executed.
Set "individual" as the operation method for the point table which is the last of the continuous operation.
When "loop operation using the point table selected at the start" is selected, the positioning operation is the loop. To stop
the operation, turn OFF the STF (STR) signal, or turn ON the X87 (sudden stop) input signal.
• Individual operation is only executed in the selected point table. The dwell time setting is disabled in individual operation.
• Continuous operation setting is not available for the point table 15 ("0, 2, 10, 12, 100, 102, 110 or 112" can be set to
Pr.1281).
