16 POSITIONING INSTRUCTION
16.1 Dedicated Instruction (Positioning Function)
875
16
DRVA [For the FX5 operand specification]
This instruction executes one-speed positioning by absolute 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 absolute drive. Specify the positioning address in the absolute system, in
which the transfer distance from the origin (absolute address) is specified for positioning.
• For (s1), specify the absolute 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 DRVA 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).
