Fanuc 10m Parameter Manual May 2026

This guide summarizes essential procedures and key parameters for the Fanuc 10M CNC control system, based on technical resources from Scribd and FactoryWiz.  1. Enabling Parameter Modification (PWE) 

Before changing any parameters, you must enable Parameter Write Enable (PWE).  Mode: Move the machine dial to MDI mode. Screen: Press the SETTINGS function key.

Setting: Locate PWE (Parameter #8000) and change it from 0 to 1. Fanuc 10m Parameter Manual

Note: The CNC will trigger a "Parameter Write Enable" alarm while this is active; this is normal and serves as a safety warning.  2. RS-232 Communication & DNC Settings 

To enable program transfers via RS-232, configure the following "Service Page" and standard parameters:  Parameter  Recommended Value Description #0000 xxx01000 ISO Mode enabled. #0020 2 I/O Channel select (Foreground). #5001 1 Device Select. #5110 3 or 4 Device Type (typically 3 for DC Codes/Xon-Xoff). #5111 1 or 2 Stop Bits (1 or 2 to match PC software). #5112 10 or 11 Baud Rate (10=4800, 11=9600). 3. Machine Accuracy & Compensation  Parameter 0000 (Bit 0-7): ISO code vs

Use these parameters to adjust machine movement and accuracy: 

How does FANUC set the backlash compensation parameters on t "0" is linear.

Section 1: Initial Setting Parameters (Axis Configuration)

This is the first stop after a battery death. The manual provides a table for:

• Parameter 0000 (Bit 0-7): ISO code vs. EIA. (Bit 4: Inch/Metric).
• Parameter 0001 to 0020: Axis configuration (X, Y, Z, 4th axis assignment).
• Example from manual: Parameter 0012 Bit 1 (LGY) – Setting this to "1" indicates a rotary axis with degrees; "0" is linear.

C. Tape/Interface Format (RS-232)

The Fanuc 10M was designed in the tape-reader era. Modern drip-feeding (DNC) requires setting these correctly for RS-232 communication.

• I/O Channel: Selects which port is active (Tape Reader vs. RS-232).
• Baud Rate: Must match the PC sending the data (commonly 4800 or 9600).
• Stop Bits/Parity: Usually set to 2 stop bits and Even parity for older Fanuc controls.
• ISO/EIA Code: The machine must be set to accept the code format used by your CAM software (usually ISO/ASCII).
