4.3 Safety functions 4300 Safety functions 4- Funkt_Sicherheitsfunktion_Allg
Safety functions maintain a safe condition on a plant or prevent hazard-
ous conditions arising on a plant.
The safety functions for electrical drives are defined in EN 61800-5-2.
The safety card implements the following safety functions:
Funkt_Sicherheitsfunktion_Basis  Safe stop 1 (SS1)
 Safe stop 2 (SS2)
 Safe operating stop (SOS)
 Safe speed range (SSR)
 Safely limited speed (SLS)
 Safe direction (SDI)
Funkt_Sicherheitsfunktion_SBC  Safe brake control (SBC)
Funkt_Sicherheitsfunktion_SBT  Safe brake test (SBT) (not defined in EN 61800-5-2)
Funkt_Sicherheitsfunktion_Eing
Activation of safety functions
 The safety functions are activated using the single-pole safe inputs on
the safety card.
 These inputs operate in accordance with the failsafe principle (on
switching off). The safety control system activates the safety func-
tions via a 1/0 pulse edge.
Funkt_Sicherheitsfunktion_Rueck
Feedback from the safety functions
 Message via single-pole semiconductor outputs
– “1” Signal: Inside the set limit values
– “0” Signal: Outside the set limit values
Funkt_Sicherheitsfunktion_Kombi
Simultaneous activation of safety functions
 All safety functions can be active at the same time. However, safety
function SS1 has priority over all other safety functions.
 If SS1 is activated, the drive is stopped in accordance with its config-
uration.
 During this time, no other safety functions may be processed or called
up.
Funkt_Sicherheitsfunktion_Fehler
Reaction to limit value violations and errors
 When set limit values are exceeded, the E-STOP braking ramp is ac-
tivated.
 The safety function STO is activated if there are any internal errors on
the safety card or servo amplifier. The power element is switched off.
