4.3 Safety functions
4 Function Description
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_SS2_Ueberwach_Bremsrampe_Normal  Braking ramp in normal operation
The drive starts with the configured braking ramp when safety func-
tion SS2 has been activated. Once the time has elapsed, SOS is ac-
tivated.
Sicherheitsfunktion_SS2_SOS_Ueberwach_Stillstand_Pos  Standstill position
– The safety function monitors whether the standstill position re-
mains within a configured tolerance window.
– Safety function SS1 (E-STOP braking ramp) is activated if the
standstill position leaves the tolerance window.
Sicherheitsfunktion_SOS_Ueberwach_Stillstand_Auto  Automatic SOS at standstill
A standstill threshold for activating the safety function SOS can be
specified in the Configurator.
Safety function SOS is activated when
– standstill is achieved while the SOS delay time is running.
– the SOS 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.
Sicherheitsfunktion_SS2_Ausloesung
Safety function is activated
 By a 1/0 pulse edge at the input "SS2 Activate".
Sicherheitsfunktion_SS1_SS2_Ausloesung  The method by which the servo amplifier receives the command for
controlled braking of the motor is defined in the Configurator:
– Drive-activated: After the safety function is triggered, the safety
card issues a command to the servo amplifier for controlled braking
of the motor. The braking ramp is configured in the Configurator.
– Controller-activated: After the safety function is triggered, the
control system issues a command to the servo amplifier for con-
trolled braking of the motor. The braking ramp must only be con-
figured in the Configurator if monitoring of the braking ramp is also
activate there.
