11 POSITIONING INSTRUCTION
11.1 Positioning Instruction
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
Built-in positioning manual.
Precautions
Three devices are occupied from the device specified in (s) and (d1). Make sure that these devices are not used in other
controls.
For other precautions, refer to
Built-in positioning manual.
