POINT
The dedicated instructions of QD77MS16 can be used for only axis 1 to 4. They
cannot be used for axis 5 to 16. If the ZP.PSTRT5 to ZP.PSTRT16 or ZP.TEACH5
to ZP.TEACH16 is executed, the error "Program code error" (error code: 4002) for
PLC CPU and the error "PLC CPU error" (error code: 803) for QD77MS16 will
occur and positioning cannot be started.
Refer to "QCPU User's Manual (Hardware Design, Maintenance and Inspection) for
error of PLC CPU".

15.2 Interlock during dedicated instruction is executed
The positioning start instruction (ZP.PSTRT ) and teaching instruction (ZP.TEACH )
cannot be executed simultaneously in each axis. If they are executed at the same time,
the second and later instructions are ignored by an internal interlock (no error will
occur).
The timing of the positioning start instruction (ZP.PSTRT ) is as shown below.
