Chapter 5 Positioning Instructions
5 - 74
•When the instruction is executed, the sub-axis does not out real pulses (at this time, the in-
operation-state flag (X-axis: %KX6720, Y-axis: %KX6880) of the sub-axis is ON), and the STEP
of the sub-axis starts up when the main axis MST_AXIS is at the position set up in the
MST_ADDR.
•The position synchronization instruction can be executed only when the Origins for both of the
main axis and sub-axis have been determined. if the Origin of the main axis or sub-axis has not
been determined at the start of the APM_SSP instruction, error code 346 or 344, respectively, will
be outputted to STAT.
•When using this instruction, set up the main axis and sub-axis with different axis. Otherwise, error
code 347 will be outputted to STAT.
•To cancel the execution of position synchronization instruction after it is given, execute the stop
instruction (APM_STP) to the sub-axis.
(2) Sample Instruction
•the sample program below shows the operation of the position synchronization start-up
instruction.
(a) Sample Program
•In the sample program below, where the Y-axis is the sub-axis and X-axis is the main axis, when
the main axis position is at 100,000, the operation data in the No. step of the sub-axis is started
up.
