Safety Stop Function
DANGER!
The activation of the safety stop function does not guarantee electrical safety of
the motor terminals they are not isolated from the power supply in this condition.
DANGER!
L L'activation de la fonction d'arrêt de sécurité ne garantit pas la sécurité électrique
des bornes du moteur (elles ne sont pas isolées de l'alimentation électrique dans
cet état).
ATTENTION!
In case of a multiple fault in the power stage of the inverter, the motor shaft can
rotate up to 360/(number of poles) degrees even with the activation of safety stop
function. That must be considered in the application.
NOTE!
Inverter safety stop function is only one component of the safety control system of a
machine and/or process. When inverter and its safety stop function is correctly used
and with other safety components, it's possible to fulfill the requirements of standard
EN 954-1 / ISO 13849-1, Category 3 (machine safety) and IEC/EN 61508, SIL2 (safety
control/signalling applied to processes and systems).
