Absolute Position Data Transfer Protocol - Mitsubishi Electric MELSERVO MR-J5 Series User Manual

Absolute position data transfer protocol

Data transfer procedure
Each time SON is turned on, such as when the power is switched on, the controller needs to read the current position data in
the servo amplifier.
If this operation is not performed, position mismatch may occur. Perform time-out monitoring on the controller side.
