4.3.5 Safely limited speed - SLS
Safely฀limited฀speed฀-฀SLS 4- Sicherheitsfunktion_SLS_Ueber
The฀safety฀function฀"safely฀limited฀speed"฀(SLS)฀monitors฀the฀drive฀to฀
check฀that฀it฀stays฀within฀a฀defined฀speed฀limit.
Sicherheitsfunktion_Sxx_Voraussetzung_S1
Prerequisites฀for฀normal฀operation:฀

Input฀"SS1฀Activate"฀and฀"SS1฀SIL3/Reset":฀"1"฀Signal฀(+24฀VDC)

"Ready"฀output:฀"1"฀Signal฀(+24฀VDC).฀The฀safety฀card฀is฀ready฀for฀op-
eration.

"STO฀Acknowledge"฀output:฀“0”฀Signal
Sicherheitsfunktion_SLS_Voraussetzung

Input฀"SLS฀Activate":฀"1"฀Signal฀(+24฀VDC)
Sicherheitsfunktion_Sxx_Voraussetzung_SIL3

To฀achieve฀SIL3฀or฀Ple:฀Connect฀the฀output฀"STO฀SIL3"฀to฀servo฀am-
plifier฀terminal฀X4A/฀3.
Sicherheitsfunktion_SLS_Ausloesung
Safety฀function฀is฀activated฀

By฀a฀1/0฀pulse฀edge฀at฀the฀input฀"SLS Activate".
Sicherheitsfunktion_SLS_Reaktion
Reaction:

SLS฀delay฀time฀starts

Once฀the฀SLS฀delay฀time฀has฀elapsed,฀the฀speed฀is฀monitored.

Output฀"SRA฀Acknowledge":฀"1"฀Signal

If฀the฀limit฀value฀is฀exceeded,฀safety฀function฀SS1฀(E-STOP฀braking฀
ramp)฀is฀activated.
Sicherheitsfunktion_SLS_SSR_Toleranz
A฀tolerance฀range฀may฀also฀be฀set฀for฀the฀limit฀values฀used฀to฀monitor฀
the฀speed.฀This฀tolerance฀range฀modifies฀the฀set฀limit฀values.฀As฀a฀result,฀
one-off฀or฀periodic฀overshoots฀that฀exceed฀the฀limit฀values฀can฀be฀toler-
ated.
The฀following฀values฀can฀be฀set฀for฀the฀tolerance฀range:

Tolerance฀amount,฀which฀takes฀into฀account฀the฀size฀of฀the฀over-
shoots.

Tolerance฀time,฀which฀takes฀into฀account฀the฀length฀of฀the฀overshoots

Tolerence฀period฀that฀takes฀into฀account฀the฀variation฀period
Activate฀the฀tolerance฀range:

The฀tolerance฀range฀becomes฀active฀the฀first฀time฀the฀speed฀limit฀val-
ue฀is฀exceeded฀(see฀flowchart).
INFORMATION
See฀the฀Configurator's฀online฀help฀for฀details฀of฀how฀to฀set฀the฀
parameters฀for฀the฀tolerance฀range.
