Connecting safe outputs

F-DO "Internal event"
This signal changes from "1" to "0" when a safety alarm occurs in the drive group, irrespective
from which axis. The signal can be considered as a group error. The individual "Internal event"
signals of each drive group should be ANDed and output via an F-DO. The signal should be
wired to a PLC input through one channel. In this case, the F-DO is processed in a non-safety
related fashion. If a safety problem occurs on an axis, this signal, which will have the level "0"
in this case, should be used to remove the travel enables of the other axes/spindles.
F-DO "SSM feedback signal active"
The SSM velocity can be freely parameterized. The signal switches to "1" if the speeds of all
axes/spindles in the group fall under the parameterized limit. The signal is used to interlock
the protective door.
The individual "SSM feedback signal active" signals of each drive group should be ANDed and
output via an F-DO:
