Fx3 Compatible Sm/Sd - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Complete flag and completion of positioning operation
If the complete flag of a positioning instruction is turned on, then the execution of the instruction (such as pulse outputting
operation) is complete (Page 77 Complete flag). However, it is not certain whether the servo motor has stopped or not.
Check the "positioning completion" signal of the servo amplifier (drive unit) to determine whether the servo motor has
stopped.
Write during RUN
Do not change the program if a positioning instruction is being executed (pulses are being output) in the RUN mode.
Operations will be performed as shown in the following table if a program is changed during instruction execution in RUN
mode.
Also do not change the program if PWM is being executed in RUN mode.
For details on the PWM/DPWM instructions, refer to MELSEC iQ-F FX5 Programming Manual (Instructions, Standard
Functions/Function Blocks).

FX3 compatible SM/SD

FX3 compatible devices can be used. Devices other than the instruction execution complete flag (SM8029) and the instruction
execution abnormal end flag (SM8329) are not supported for high-speed pulse input/output module.
Both the FX5 dedicated devices and FX3 compatible devices can be used if they have the same functionality.
For details on devices, refer to Page 47 Details of Parameters.
