Absolute Position Detection System

With the use of the servo absolute position detection system, the positioning uses the current ABS value read-out (DABS)
instruction to read out the current value (absolute position (ABS) data) from the MR-J4A or MR-J3A servo amplifier.
The data is converted into pulse when being read.
DABS
This instruction reads the absolute position (ABS) data when the servo amplifier is connected. The data is converted into
pulse when being read.
