MAC mini iH Series Operation ManualProgram4.5.9. Machine zero returnMZRNThis code rotates the table to the mechanical zero position. This is called MZRN.When MZRN is finished, ZRNFIN and BLKFIN signals are outputted.The G23 code rotates the table at the rapid traverse set to PRM003 as MZRN feed.Though MZRN direction is set to PRM016, when SHOT CUT ZRN of PRM017 is set, PRM017takes precedence.When G23 is commanded at MZRN position, MZRN is performed again and BLKFIN and ZRNFIN areoutputted. However, when UNIDIRECTIONAL is valid, the unidirectional motion is performed.Program FormatG23JBoldface and italic type characters can beabbreviated.G23 Machine zero return (MZRN)DescriptionJ Program jump destination Setting range -1 999J-1 Subprogram return commandAddress J is the same as “Non-G code Type (Standard)”.Concerned parametersTiming chartPRM003PRM016PRM017PRM018StartThe MZRN feed is rapid traverse.Selects MZRN direction.0 CW direction1 CCW directionSelects ZRN SHORT CUT DIR.0 INVALID1 VALID2 ZRN SHORT CUT DIR VALID of OPT POS spec. typeSets the angle position (M/C coordinate system) that is theboundary of ZRN SHORT CUT DIR of OPT POS spec. type.RotationClampedBLKFINZRNFINIn case of PRM035=0, BLKFIN is turned OFFat START OFF.BLKFIN TimerPRM035 (STD Set value: 500msec)UnclampClampMZRN FIN OUTPUT(500msec fixed)KITAGAWA O4-27
