4.3 Safety functions
4 Function Description
Features฀of฀the฀safety฀function:

The฀motor฀becomes฀torque-free฀and฀no฀longer฀generates฀any฀hazard-
ous฀movements.

The฀safety฀function฀"safe฀stop฀1"฀corresponds฀to฀a฀category 1฀stop฀
(controlled฀braking)฀in฀accordance฀with฀EN 60204-1.
Sicherheitsfunktion_Sxx_Ueberwach
The฀safety฀card฀monitors฀the฀following฀functions:฀
Sicherheitsfunktion_SS1_SS2_Ueberwach_Bremsrampe

Braking฀ramp
In฀the฀Configurator,฀the฀braking฀ramp฀is฀specified฀and฀monitoring฀is฀
activated.฀The฀braking฀period฀depends฀on฀the฀speed฀of฀the฀motor฀
when฀braking฀is฀started.฀
The฀braking฀ramp฀can฀be฀monitored฀via฀a฀maximum฀position฀error฀
specified฀in฀the฀Configurator.
Sicherheitsfunktion_SS1_Ueberwach_Bremsrampe_Normal

Braking฀ramp฀in฀normal฀operation
The฀drive฀starts฀with฀the฀configured฀braking฀ramp฀when฀safety฀func-
tion฀SS1฀has฀been฀activated.฀Once฀the฀time฀has฀elapsed,฀STO฀is฀ac-
tivated.
Sicherheitsfunktion_SS1_SS2_Ueberwach_Bremsrampe_Not_Halt

E-STOP฀braking฀ramp:
The฀drive฀starts฀with฀the฀configured฀braking฀ramp฀when฀
– there฀is฀an฀internal฀error฀
– limit฀values฀are฀exceeded
Sicherheitsfunktion_STO_Ueberwach_Bremsrampe

Safety฀function฀STO฀is฀activated฀when฀
– the฀actual฀braking฀period฀is฀longer฀than฀the฀configured฀STO฀delay฀
time.฀
– the฀configured฀limit฀value฀for฀the฀position฀error฀is฀exceeded.
– another฀error฀occurs฀while฀SS1฀is฀activated
– the฀STO฀delay฀time฀has฀elapsed
Sicherheitsfunktion_STO_Ueberwach_Stillstand_Auto

Automatic฀STO฀at฀standstill
A฀standstill฀threshold฀for฀activating฀the฀safety฀function฀STO฀can฀be฀
specified฀in฀the฀Configurator.฀
Safety฀function฀STO฀is฀activated฀when฀
– standstill฀is฀achieved฀while฀the฀STO฀delay฀time฀is฀running.
– the฀STO฀delay฀time฀has฀elapsed.
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_Sxx_Voraussetzung_SIL3

To฀achieve฀SIL3฀or฀Ple:฀Connect฀the฀output฀"STO฀SIL3"฀to฀servo฀am-
plifier฀terminal฀X4A/฀3.
