Processing details
This instruction executes one-speed positioning by incremental drive. Specify the positioning address in the incremental
system, in which the transfer direction and transfer distance from the current position (relative address) are specified for
positioning.
• For (s1), specify the relative positioning address in user units. (The address must be within the range of -2147483647 to
+2147483647 number of pulses.)
• For (s2), specify the command speed in user units. (The speed must be 200 Kpps or lower in frequency.)
• For (d1), specify the axis number from which pulses are output.
• For (d2), specify the bit device of the normal complete flag or abnormal end flag for the DDRVI instruction.
For details on the function and error code, refer to MELSEC iQ-F FX5 User's Manual (Positioning Control - CPU module
built-in, High-speed pulse input/output module).
