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.
