Function:
When the emergency-stop button is actuated, the motor is stopped according to stop category 1 of EN 60204-1. (Safe stop 1 according to DIN EN 61800-5-2:2008-04 chapter 4.2.2.3 function c)
The delay time of the safety relay must be longer than the resulting QSP time. Con-sider the delay time tolerances of the safety relay. The values to be set depend on the application. In the drawing, the delay time of the safety relay is set to 3s.
This application example can be used in all technology applications where the QSP can be activated via a digital input of the drive controller.
Faults have been excluded for protected cables (according to DIN EN ISO 13849-2:2013-02 and IEC 61800-5-2:2008-04). This applies to cables which are protected by a cable duct and installed inside the control cabinet.
