Hello all,
If a system has:
-a servo drive
-a safety relay (enables the servo drive)
- (5) gate switches in series (Channel 1 and 2)
Would this be considered (5) seperate safety functions (gate switch + relay + drive) repeated (5) times. Or would this be (1) safety function with all (7) items as subsystems?
I would think the later of the two, but a machine builder has sent me an example with it all as separate safety functions.
Any advice is greatly appreciated.
