16 POSITIONING INSTRUCTION
16.1 Dedicated Instruction (Positioning Function)
871
16
DDRVI [For the FX5 operand specification]
This instruction executes one-speed positioning by incremental drive.
Setting data
■
Descriptions, ranges, and data types
*1 Specify K1 to K4 (axis 1 to 4) for the CPU module, and K5 to K12 (axis 5 to 12) for the high-speed pulse input/output module.
■
Applicable devices
*1 T, ST, C cannot be used.
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).
