Bit-level switches that interface directly with the machine tool builder's (MTB) ladder logic. 2. Unlocking and Accessing Parameters (Setup Procedure)
The manual organizes parameters into logical groups to facilitate initial setup and fine-tuning:
Defines the negative software overtravel limit. mitsubishi meldas 64 parameter manual
| | What It Affects | Example & Key Parameter Numbers | | :--- | :--- | :--- | | Axis Configuration | Defines basic machine setup like axis existence, names, and encoder types. | #1001 to #1042 configure the machine's base setup; #2049 (often for absolute encoder settings) tells the control if an axis has an absolute encoder. | | Communication (I/O) | Sets the baud rate, parity, and data bits for RS-232 communication. | Accessed via TOOL PARAM → I/O PAR . | | Servo Control & Tuning | Governs how smoothly and accurately the servo motors move. | Parameters like #2201 (Position Loop Gain) and #2230 (SHG control gain) affect precision, with higher settings improving accuracy but potentially causing vibration. | | Spindle Control | Configures the spindle drive, including maximum RPM, gear ranges, and orientation for rigid tapping. | Depends heavily on the specific spindle drive installed and is covered in detail in the Servo/Spindle parameter manuals. | | PLC and Macro Control | Controls the machine's PLC (ladder) logic and macro programming. | Parameter #1121 (Setting to 0 disables edit lock), #6001 (edit lock for sub programs), and #8101 (controls ladder display). |
Accessing these parameters on the machine's control panel is straightforward. The exact key names may vary, but the standard method is: Bit-level switches that interface directly with the machine
Controls the fine-tuning precision of the axis positioning loop. 4. How to Back Up and Restore Parameters
: Some systems require changing the #1060 SETUP parameter to 1 to enable specific initialization or editing functions. | | What It Affects | Example &
Many controllers also have a special procedure to access , which may require keying in a specific code like "Y" before the standard menu appears.
Given that parameters define the very behavior of your CNC, losing them can render the machine inoperable. A regular backup is essential.
