比如一个用户循环用于屏蔽某些轴的功能：

N5 PROC DISABLE_SPI(INT _SP1, INT _SP2, INT _SP3)
N10 Def INT _idx
N15 DEF INT _SPNR[4]
N20 For _idx = 1 to 6
stopre
N30 $MA_REFP_CAM_IS_ACTIVE[SPI(_IDX)]=1
N35 $MA_CTRLOUT_TYPE[SPI(_IDX)]=1
N40 $MA_ENC_TYPE[0,SPI(_IDX)]=1
N45 $MA_SIMU_AX_VDI_OUTPUT[SPI(_IDX)]=0
N50 $MA_REFP_CAM_IS_ACTIVE[SPI(_IDX)]=1
N55 $MA_GEAR_STEP_CHANGE_ENABLE[SPI(_IDX)]=1
N60 $MA_ENC_REFP_MODE[0,SPI(_IDX)]=7
N65 $MN_DRIVE_IS_ACTIVE[_idx-1]=1
ENDFOR
N70 _SPNR[1]=_SP1 _SPNR[2]=_SP2 _SPNR[3]=_SP3
N75 For _idx = 1 to 3
N80 IF _SPNR[_idx]==0 GOTOF _END
N85 $MA_REFP_CAM_IS_ACTIVE[SPI(_spnr[_idx])]=0
N90 $MA_CTRLOUT_TYPE[SPI(_spnr[_idx])]=0
N95 $MA_ENC_TYPE[SPI(_spnr[_idx])]=0
N100 $MA_SIMU_AX_VDI_OUTPUT[SPI(_spnr[_idx])]=1
N105 $MA_GEAR_STEP_CHANGE_ENABLE[SPI(_spnr[_IDX])]=0
N110 $MA_ENC_REFP_MODE[SPI(_spnr[_idx])]=1
N115 $MN_DRIVE_IS_ACTIVE[_SPNR[_idx]-1]=0

N120 _END:
N125 endfor
stopre
N130 m30

执行DISABLE_SPI(1)就可以将第一个主轴屏蔽，执行完毕相应需要修改的参数同时就自动修改了！ 这又是什么功能？到底是怎么用这一功能的？望高手指教！
