Mitsubishi Meldas 64 Parameter Manual [verified] Jun 2026
I can provide the exact step-by-step register breakdowns for your specific scenario.
Let’s pool knowledge. Drop your machine model + control suffix (e.g., MELDAS 64M, 64L) below 👇
Both the parameter and alarm/parameter guides stress a crucial point: while they explain how the NC works in general, . They are the ones who integrate the NC with the specific machine's hardware. This is because the MTB tailors parameters to their machine's unique axis drives, spindle, and tool changer, meaning the same parameter number can have different functions depending on the builder.
To unlock parameter editing, you must change the setup parameter lock. Locate the parameter often labeled or "#1060 Setup" and change the value from 0 to 1 (or input the factory password if prompted by your machine builder).
The series (including M64, M64A, and M64S) uses several manuals for parameter management. The primary guide for general configuration is the MELDAS C6/C64/C64T Parameter Manual mitsubishi meldas 64 parameter manual
| | Likely Cause | Parameter-Related Fix | | :--- | :--- | :--- | | Z70: ILLEGAL ABS | The absolute positioning data for an axis is lost or invalid. Often occurs after a battery failure or a loose servo encoder connector. | Check parameters related to absolute encoder use (e.g., #2049 for the Meldas 60 series). Setting this parameter correctly tells the control which axes have absolute encoders. | | S01, S03, S04 Alarms | These are general system alarms. S01 often indicates a system error, S03 a servo alarm, and S04 a drive alarm. | While often reset by power cycling ( S01 , S04 ) or pressing RESET ( S03 ), recurring issues usually point to a parameter problem. The alarm/parameter guide will list specific alarm codes and their meanings. | | RS-232 Communication Failure | The CNC cannot connect to a PC for data transfer. | Go to TOOL PARAM → I/O PAR and verify the baud rate, parity, and other settings match your PC's configuration. Ensure the correct port is selected. | | Unexpected Axis Movement (e.g., G28 issues) | The machine performs a reference return (G28) differently than expected. | Misconfiguration of parameters controlling reference return (like G28 behavior) can cause unexpected movement. Check your machine builder's manual for which parameters control this function. | | Screen Language in Chinese | After a system reset, the default language setting may be Chinese. | Navigate blindly to parameter #1043 and set its value to 1 to switch the language to English. |
: Critical for motor tuning and axis movement accuracy.
Determines how aggressively the axis chases the commanded position. Higher values improve accuracy and reduce follow error but can cause machine vibration if set too high.
The MELDAS 64 system organizes parameters into logical groups to simplify navigation and troubleshooting. I can provide the exact step-by-step register breakdowns
This happens after changing battery packs or disconnecting feedback encoders. You must use the axis parameter manual to re-establish the absolute position reference point (Grid Shift / Zero point initialization).
The manual is structured into logical blocks to facilitate rapid navigation during machine commissioning or repair:
