Position control under vector control and PM sensorless vector control
Setting the waiting (dwell) time
● Set the waiting (dwell) time which is the interval from the completion of the position command
of a selected point table to the start of the position command of the next point table.
● Set the dwell time from 0 to 20000 ms for parameters corresponding to each point table.
Auxiliary function setting
● Set the handling and operation methods of the position data in each point table.
● Set the auxiliary function for parameters corresponding to each point table.
Auxiliary function parameter
10 (initial value)
Tab. 5-55:
● For the sign, select the sign of position data.
● For the command method, select the absolute position command or incremental position com-
mand. 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 "continuous 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 that will be the last of the continuously operated point tables.
When "continuous operation using the point table selected at the start" is selected, the position-
ing operation is repeated. 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).
