Backup - Mitsubishi Electric MELDAS C6 Instruction Manual

2.7.9.1 Backup

SRAM backup of the auxiliary axis parameters and absolute position restoration during amplifier
replacement are executed on the BACKUP screen.
Only execute the operations during amplifier replacement.
(1) Procedure during MR-J2-CT amplifier replacement
The following shows the procedure during MR-J2-CT amplifier replacement. The operation is
carried out on the BACKUP screen.
The absolute position of the current MR-J2-CT must be established first before carrying out this
operation.
• SRAM backup of the auxiliary axis parameters
The current amplifier data is backed up in the SRAM of the CNC when the amplifier is replaced.
The following shows the procedure for SRAM backup of the auxiliary axis parameters.
Input "(1) (a)" from the BACKUP screen. (a: axis No. (1 to number of connected axes))
After inputting, the message "CONTINUE Y/N" will appear for confirmation of the data backup.
The data is backed up in the SRAM only if "(Y)" is input.
The message "BACKUP COMPLETE" will appear when the backup operation is finished.
If MR-J2-CT is not connected, the message "E01 SETTING ERROR" will occur, and the data
will not be backed up.
After the procedure is finished, turn OFF the CNC and MR-J2-CT power supply, and replace
MR-J2-CT amplifier.
After replacing the MR-J2-CT amplifier, set the MR-J2-CT rotary switch to "7". Turn the CNC
and MR-J2-CT power supply ON, wait for the 7-segment display to change from dot display,
and then turn the power OFF. The auxiliary axis parameter data is written and the absolute
position restored after the axis is set with the rotary switch and the power is turned ON again.
(Note) Turning ON the power supply with the MR-J2-CT rotary switch set to "7" initializes the

out this operation, the machine position will be created with the old amplifier's data.
