SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
3-123
Note
The appropriate signals should be accordingly processed by the PLC in the
drive monitoring channel (refer to Chapter 3.9.2, "Signal processing for the
drive monitoring channel").
For safe evaluation of the cam signals, the SGA "axis safely referenced" must
be taken into account.
The SGA "axis safely referenced" can be logically combined using the SGA
"SBH/SG active" if the signal is used to enable a protective zone (refer to
Chapter 7, "Circuit examples for Safety Integrated")
Advantage:
An AND logic operation in the NCK monitoring channel can then be
implemented by means of machine data (refer to Chapter 4, "Machine data
for SINUMERIK 840D").
