Example 2 – delaying the transition from STOP F to STOP B
The same parameterization as in Example 1 is shown in Fig. 6-8. However, when a
STOP F occurs, no monitoring function is active. At instant in time t2, a monitoring
function is activated. ESR is only started if there is a STOP F with active monito-
ring function.

Fig. 6-8
The following actions take place at the following instants in time:
t1:
STOP F occurs, no response
t2:
At any time after t1, a monitoring function is activated. At this instant in time, the
transition to a STOP B is started and bits 1 in $A_XFAULTSI and $VA_XFAULTSI
of this axis are set.
t3:
500 ms after t2, braking starts along the parameterized ramp
t4:
STOP B is initiated 2.5 s after t2. The axis is already stationary at this time, which
means that the pulses can be immediately cancelled.
