i700 BS - Safe Stop 1 and safe brake control - PL e
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 61800-5-2:2017-11 chapter 4.2.3.3 function c)
100ms before the end of the stop time, the power supply to the brake is switched off. (Safe brake control according to DIN EN 61800-5-2:2017-11 chapter 4.2.5)
The delay time of the “Safety” program must be longer than the resulting xHalt time. Consider the delay time tolerances in the safety PLC. The values to be set depend on the application.
When the STO function is deactivated, the safe brake control remains deactivated for another 100ms so that, for example, a suspended load does not sag.
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.
Safety information / disclaimer
The drive-based safety application and parameterisation notes are examples of possible subfunctions in machines.
The T10D value according to DIN EN ISO 13849-1, Annex C.4.2 is only indicated if a B10D value is available and the operating time is less than 20 years.
Commissioning is prohibited until the machine has been checked in accordance with the regulations set out in the relevant EU directives / national laws.
The safety instructions contained in the technical documentation must be observed.
Using the examples does not exempt the user from careful project planning. Lenze does not assume any liability for potential damage and consequential damage that may occur.
