(c) Function
• These instructions start positioning with data stored in the device specified by
without using "Positioning data" No.1 to 10 set beforehand using the programming tool.

• When positioning control starts successfully, the Axis 1 busy (SM1840) turns on. (1))
• When positioning is complete, the Axis 1 busy (SM1840) turns off and Axis 1 positioning completion
(SM1841) turns on. (2)) (During speed control, causes that stop the axis include execution of the Axis stop
instruction (IPSTOP1) and aborted operation due to error detection. Accordingly, the Axis 1 positioning
completion (SM1841) does not turn on.)
• The Axis 1 positioning completion (SM1841) will turn off the next time the applicable axis is started.
• If operation cannot be started because
• If the Axis stop instruction (IPSTOP1) is executed or an error is detected during positioning, the axis
decelerates to a stop and the Axis 1 positioning completion (SM1841) does not turn on.
The number of steps is basically two.
Using values set for the specified device,
positioning is started.
Positioning data are not used.
