Whuttup CNCzone homies ?

Does anyone know how to disable the "auto-coupler" (hydraulic fixture clamping device for pallet-mounted fixturing) via PC-parameter on a Makino A66 horizontal machining center with Fanuc 16 controller? (Like you'd enable or disable any add-on device)

Makino does not provide a dynamic ladder display so I can't backtrack thru it and find the setting.

Please advise.
