I have a VMC equiped with fanuc OM-C. It's Parameters got lost. Presently I looking for it's option parameters # 900. I have a backup of it's parameters but it does not contains 900 parameters. I would much appreciate for sending me option parameters along with every parameter bit description. Can I use Fanuc OM-D's 900 parameters instead of OM-C. Kindly help me to solve this problem.
