Fanuc Pmc Eprom Convert Tool May 2026

The Fanuc PMC EPROM Convert Tool is a specialized software utility used to manage, backup, and convert data stored on EPROM (Erasable Programmable Read-Only Memory) chips in older Fanuc CNC systems. These chips often store critical sequence programs (ladder logic) for Fanuc series such as 0, 3, 6, 10, 11, and 15. Purpose and Importance

• Loss of Comments: When logic is burned to an EPROM, symbolic comments (descriptions of inputs/outputs like "Coolant Pump") are usually stripped out. The Convert Tool recovers the logic, but the result is a "bare" ladder diagram with only addresses (e.g., R100, Y5.2). This makes troubleshooting difficult without reverse engineering.
• Compatibility Issues: There are many variants

The EPROM Challenge

EPROMs are physical chips that require a UV eraser to clear and a specialized programmer to write. They are prone to:

Step 5: (Optional) Write Back to EPROM or New Media

• For an original machine, convert back from .LAD to EPROM binary and burn a new EPROM.
• For a modernized machine, load the ladder via memory card, Ethernet, or USB into the new Fanuc control.

You must select the correct PMC type (e.g., PMC-SA1, SB3, etc.) in the software before importing; choosing the wrong model will cause conversion errors. Older Systems:
