Select fail-safe command source
Parameter Description Unit Default Min. Max.
P9603 = ? SI Selection of Safety Source
Fail-safe parameter for selection of the fail-safe input signals. The fail-
safe input signals can be taken either from PROFIsafe or from the
digital inputs of G120.
Selects either safe digital inputs or PROFIsafe .
• Bit 00 = 1/0: SLS activated/deactivated via FDI1A and FDI1B
• Bit 01 = 1/0: SLS activated/deactivated via FDI0A and FDI0B
• Bit 02 = 1/0: SS1 activated/deactivated via FDI1A and FDI1B
• Bit 03 = 1/0: SS1 activated/deactivated FDI0A and FDI0B
• Bit 04 = 1/0: STO activated/deactivated FDI1A and FDI1B
• Bit 05 = 1/0: STO activated/deactivated FDI0A and FDI0B
• Bit 07 = 1/0: SLS, SS1 and STO activated/deactivated via
PROFIsafe
Note:
• If Bit 07 = 1, all other bits must be set 0

Consistency check time of fail-safe digital inputs
Parameter Description Unit Default Min. Max.
P9650 = ? Safe input debounce delay time
Defines the maximum allowed debounce delay between the two safe
digital input pins. If both safe digital inputs are not consistent after this
time a fault will be generated (1600.108 or 1600.208).
