16 POSITIONING INSTRUCTION
16.1 Dedicated Instruction (Positioning Function)
859
16
32-bit data ABS current value read
DABS
This instruction reads the absolute position (ABS) data when a servo amplifier (equipped with the absolute position detection
function) is connected. The data is converted into pulse when read.

Processing details
This instruction reads the absolute position (ABS) data when a servo amplifier (equipped with the absolute position detection
function) is connected. The data is converted into pulse when being read.
• For (s), specify the head device number that inputs the output signal for absolute position (ABS) data from the servo
amplifier.
• For (d1), specify the head device number that outputs the absolute position (ABS) data control signal to the servo amplifier.
Be sure to use transistor outputs for the CPU module outputs.
• For (d2), specify the device that stores the absolute position (ABS) data read from the servo amplifier.
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).
