Stored Stroke Check in Fanuc Control

Dear all,

Can any body help me to solve my problem? I have one VMC machine with fanuc contro 0i-Mc. I was getting problem of Z axis hence I have removed axis drive and serviced the drive and again installed but after restarting of machine and reference done when I am going to run the spindle, one message is coming that: Reference the X axis and check entire stroke to begin auto cycle.

Please help me if any one knows the procedure how to chck the stored stroke.

Thanks and Regards
