After changes, return the setting to 0 to prevent accidental modifications. Common Exclusive Use Examples Get to know how to change the Keep Relay!
The primary "exclusive" role of keep relays is to act as software-driven switches that bridge the gap between fixed CNC parameters and the machine tool builder's (MTB) custom ladder logic.
Builders use keep relays to "use or not use" specific machine units, such as enabling/disabling a chip conveyor, high-pressure coolant, or an automatic door. System Configuration: Certain keep relays (specifically
Typically reserved for builder-defined machine sequence logic.
Often designated as "System Keep Relays" that handle internal CNC-to-PMC communication states. How to Modify Keep Relay Parameters
Changing these parameters requires cautious access to the PMC maintenance screens. Set the machine to MDI mode .
Press the key, find the "SETTING" soft key, and change "PARAMETER WRITE" from 0 to 1. Navigate to PMC Maintenance: Press the [SYSTEM] function key.
Keep relays are organized by address (e.g., K0, K1, K2) and then by individual bits (0 through 7).
) are reserved for Fanuc system functions, such as enabling ladder editing or controlling how data is backed up to flash memory.
Move the cursor to the specific bit and enter the new value (0 or 1).
