SE1 or SE2 is selected when this SGE is activated and the SE function is
active.
0 signal: SE1 is selected
1 signal: SE2 is selected
16 overrides for the limit value of safely-reduced speeds 2 and 4 can be defined
using the SGEs. This means that the limit values for SG2 and SG4 can be
more finely graduated.
An override factor of between 1 and 100% can be assigned to the selected
override via the following machine data:
For 840D MD 36932: $MA_SAFE_VELO_OVR_FACTOR[n]
(override factor safely-reduced speed)
For 611 digital MD 1332: $MD_SAFE_VELO_OVR_FACTOR[n]
This signal is used to initiate the shutdown path test for the drive monitoring
channel.
