Detailed description
2.8 Configuration
Guide values for lengthening interpolation cycle
As a guide, individual times required to perform operations within synchronized actions
(measured on an 840D with NCU 573.x) are given below:
Times may be different for other control types.
NC language
Base load for a synchronized action, if the condition is not fulfilled:WHENEVER
FALSE DO $AC_MARKER[0]=0
Read variable: WHENEVER $AA_IM[Y]>10 DO $AC_MARKER[0]=1
$R2=1
Write variable: DO
Read/write setting data:
DO$$SN_SW_CAM_MINUS_POS_TAB_1[0]=20
Basic arithematic operation, e.g. multiplication: DO $R2=$R2*2
Trigonometric functions (e.g. cos): DO $R2=COS($R2)
Start positioning axis movement: WHEN TRUE DO POS[z]=10
