16 POSITIONING INSTRUCTION
16.1 Dedicated Instruction (Positioning Function)
849
16
DVIT [For the FX5 operand specification]
This instruction executes interrupt 1-speed constant quantity feed.
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 interrupt 1-speed constant quantity feed.
• For (s1), specify the transfer distance that is output after an interrupt, in user units. (The distance must be within the range
of -2147483647 to +2147483647 number of pulses.)
• For (s2), specify the 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 DVIT 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).
Precautions
Two devices are occupied from the device specified in (d2). Make sure that these devices are not used in other controls.
For other precautions, refer to
MELSEC iQ-F FX5 User's Manual (Positioning Control - CPU module built-in, High-speed
pulse input/output module).
