Denford Cyclone with Fanuc 2li control. It has a switch on the machine bed and I have asked Denford to confirm if this is a reference switch or an over travel switch. The battery alarm came on and despite changing the battery it triggered a 300 alarm and now requires the x and z axis to be referenced. Denford have supplied me with the proceedure to change the relevant parameters but it makes reference to a "datum position". Does anyone know what this is or has carried out this procedure? Any help would be appreciated.

Yes. They will be home switches so all you need to do is replace the APC batteries on both drives then power up & home both axis to clear the alarms.
I have replaced the batteries but where do I position the drives to zero them? Do I have to manually drive them untill they hit the switches then change the parameters?

You don't need to do anything with the parameters. Just press & hold in the X & Z buttons until the axis has homed out.
If you mean the X+, X-,Z+ and Z- buttons then nothing happens. All I get is the EMG flashing on the screen.
Restarted machine again and it rehomed!!!!!!!!!! Many thanks for your help
