Certain K bits can simplify the operator's display. For example, K0.6 can hide the complex servo tuning screens, reducing confusion for general operators.

FANUC Keep Relays are displayed in a byte format consisting of 8 individual bits, numbered from right to left (Bit 0 to Bit 7).

To work with Keep Relays, you need access to the PMC maintenance mode. Here is the standard method on a Fanuc 31i/0i-D control. fanuc keep relay parameters exclusive

If your control uses a newer dynamic interface, navigate to: SYSTEM -> PMC -> PMCPARAM -> KEEP-RLY . Step 3: Locate and Alter the Target Bit

By understanding how to properly read and modify , you can significantly reduce downtime and customize machine performance to meet specific production requirements. If you're interested, I can:

Knowing these details will allow me to provide the exact bit addresses and configuration sequences for your setup. Share public link Before modifying any internal parameters or keep relays,

Never modify a single bit without backing up the CNC parameters and PMC data to a USB flash drive or memory card.

Change "Parameter Write" (PWE) from 0 to 1 . The machine will likely trigger an alarm; this is normal. Press the SYSTEM hard key.
