6 BY- Bypass- Connect to BY+ (Pin 1) to bypass STO/SBC
1.6.3.1.2 Wiring examples for the STO/SBC inputs
The wiring differs depending on the safety device used:
Manual switch covers any emergency device that can be connected directly to the safety input of the
servo drive.
If safety PLCs are used it is important to distinguish between plus-plus and plus-minus logic
PLCs using plus-plus logic must be connected to both inputs for redundancy
PLCs using plus-minus logic are only connected to the input 1 which must be bridged to input 2.
The redundant channel in this case is the pulsed safety ground signal.
Important
Please note that Safety GND is an isolated signal from drive GND.
1.6.3.1.2.1 Manual switch
Allows safety functions up to SIL 3, PL e, cat.3.
