Purpose
Subroutine 32 is executed at the first PLC cycle (SM0.1). This subroutine sets NCK interface signals according to the
machine settings defined by PLC machine data. In this subroutine, the following interface signals are set:
● DB3200.DBX6.7: feed override of the NCK channel becomes active
● DB380x.DBX1.5: measurement system 1 of the axes is active
● DB380x.DBX1.7: feed override of the axes is active
● DB1700.DBX1.3: active ROV
The following signals are reset:
● DB1700.DBX0.6:reset DRY
At the end of this subroutine, subroutine 31 (PLC_ini_USR_ini) is called. You can program the initialization of customer PLC
