This alarm triggers when reference position data is lost, usually after a dead backup battery. You must reset the home position using axis parameters #2049 and the manual reference point set sequence.
When resolving errors on a Meldas 64 control, the manual highlights several frequently adjusted parameters:
Custom macro logic and G-code styling definitions. 2. Core Parameter Classifications & Functions
In the data type field, enter 1 (or select the checkbox). Press Input or Execute to punch out the data file. Step-by-Step Parameter Restore (Reading Data) Ensure the control parameter write switch is enabled. On the control, navigate to Mainte -> I/O . Set the mode to Input . mitsubishi meldas 64 parameter manual
If parameters cannot be changed, you may need to disable the edit locks: [TOOL/PARAM] > Page 2. Set Setup Parameter Lock #1060 (SETUP) to enable one-touch setup and memory formatting options. MELDAS 60/60S Series ALARM/PARAMETER MANUAL
To edit restricted parameters, you often need to navigate to the SETUP screen and change specific lock parameters, such as setting #1121 to 0 .
Data loss due to backup battery failure is a common issue on older Meldas 64 controls. Regular parameter backups are critical. Backing Up Parameters via RS-232 / Input-Output Screen This alarm triggers when reference position data is
First, it's important to know that there are a few different manuals available for the Meldas series. The most relevant ones include:
Electronic component failure, dead backup batteries, or power surges can wipe the volatile memory of a Meldas 64 control. Regular backups are mandatory. Step-by-Step Parameter Backup (Punching Data)
Verify the bit settings in Parameter #6000 through #6050 . These map the physical emergency stop string to the CNC logic. 5. Best Practices for Parameter Management Parameter Backup Best Practices
If parts show witness marks or steps during quadrant transitions (e.g., milling a circle), adjust the backlash compensation parameters:
The Mitsubishi Meldas 64 CNC controller is a workhorse in the manufacturing industry, known for its reliability in vertical machining centers, lathes, and custom CNC machinery. However, getting the most out of this control system requires a deep understanding of its configuration.
These parameters govern the foundational configuration of the machine tool, including language settings, unit systems (inch/metric), and display options.
Rapid traverse backlash compensation value.
Note: Measure physical backlash using a dial indicator before changing these values. Input the compensation in microns. 5. Parameter Backup Best Practices
