Sequence when activated by an event: Powering-up of the NC
1. Control activates after power-up reset-sequence with evaluation of machine data:
– MD20110 $MC_RESET_MODE_MASK
– MD20150 $MC_GCODE_RESET_VALUES
– MD20152 $MC_GCODE_RESET_MODE
2. Implicit call of the parameterized user program as ASUB
3. Control activates reset-sequence with evaluation of machine data:
– MD20110 $MC_RESET_MODE_MASK
– MD20150 $MC_GCODE_RESET_VALUES
– MD20152 $MC_GCODE_RESET_MODE
