Lines N100–N105 are described in more detail in Chapter 7.3.6 "Test stop".
The programming of the function chart starts in line N110 - where the
acknowledgement button and the EMERGENCY STOP button are logically
combined. They form the internal "EMERGENCY_STOP" signal.
STOP C is selected with "EMERGENCY_STOP=0" (N210) and the timers for
the axes (N120-N140) and the spindles (N150-N170) are started. When each of
the timers has elapsed STOP A is triggered for the axes (N180) and the
spindles (N200). STOP D is not used on the NC side but is combined in the test
stop (refer to Chapter 7.3.6 "Test stop").
The power contactor K2 for the NC side is controlled using instruction line
N 230.
