Fanuc 9900 Parameter List -

FANUC CNC systems utilize parameters to define machine behavior, from servo gain to I/O assignments. Parameters 9900–9999 are distinct: they are set at the machine tool builder (MTB) level. Unauthorized or incorrect changes to these values can disable the CNC, corrupt the PMC (Programmable Machine Controller), or render the machine inoperable.
