5.8 Control modes
The behaviour of machines with SIGMA CONTROL 2 is determined by three software control
modes interacting with each other.
5.8.1 Ready control mode
The ready control mode specifies whether individual machines or machines under master control
can be activated. It evaluates the «On» and «Off» keys. The software checks whether all faults are
