Description of ACTIVE Cube Safety Function
The frequency inverters of the AGL devices series feature the integrated safety func-
tion „Safe torque off, STO“.
With a suitable external safety control device the function „Safe Stopp 1 (SS1 c)“
according to EN 61800-5-2 can be realized together with the AGL.
Definitions according to EN 61800-5-2:
STO: Dem Motor wird keine Energie zugeführt, die eine Drehung (oder bei einem
Linearmotor eine Bewegung) verursachen kann. Der Frequenzumrichter liefert keine
Energie an den Motor, die ein Drehmoment erzeugen kann.
SS1 c: Das System Sicherheitsschaltgerät + Frequenzumrichter führt die Funktion
aus:
Auslösen der Motorverzögerung und nach einer anwendungsspezifischen Zeitverzöge-
rung Auslösen der STO-Funktion.
Diese Sicherheitsfunktion entspricht dem gesteuerten Stillsetzen nach EN 60204-1,
Stopp-Kategorie 1.
Definitions according to EN 60204-1:
Stop category 0: Stop by immediate disconnection of energy supply to the machine
drive elements, i.e. uncontrolled stop.
Stop category 1: Controlled stop, where energy is still being supplied to the drive
elements of the machine to perform the stopping operation. Energy supply is stopped
only after the drive has come to a standstill.
Stop functions must always have priority over start functions and must work properly
in any operation mode.
Resetting of the stop function must not cause any dangerous state.
The mechanical elements must be dimensioned properly for the stop category used.
If, for example, a mechanical brake is applied in the case of fast-rotating machines
via stop category 0, this brake must be able to stop the machine safely. Wear and
tear of the mechanical elements must be considered during projection for the operat-
ing states and indicated in the maintenance instructions.
Stop category 0 always has priority over stop category 1.
