Synchronous Control Absolute Position System; Saving And Recovering Backup Data - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

Synchronous control absolute position system

The status (current value, reference position, etc.) of each module when performing advanced synchronous control is stored
in the Motion CPU internal backup memory. (A backup is always taken regardless of the servo amplifier used, or the valid/
invalid status of the servo motor absolute position system.) Resuming synchronous control is easy using an absolute position
compatible servo motor and servo amplifier. Refer to the following for details on how to resume synchronous control.

Synchronous control backup data stored in the Motion CPU is erased (for all axes) when the built-in memory is cleared with
the rotary switch. Set the synchronous positional relationship for each axis if necessary.

Saving and recovering backup data

Absolute position data stored inside the Motion CPU and synchronous control backup data can be saved or recovered with
the MT Developer2 backup function. By saving/recovering not only programs and parameters, but also absolute position data
and synchronous control backup data when replacing the Motion CPU module, the time take to restart can be shortened.
