Extended Functions“Braking Module” function moduleAcknowledgement of faultsWhen the Braking Module issues a fault message at binector input p3866, anattempt is made to acknowledge the fault using signal p3861 at terminal X21.1Booksize or X21.3 Chassis every 10 ms. Alarm A06900 is simultaneously isoutput.Fast DC link discharge (booksize)It is only possible to quickly discharge the DC link via the Braking Module for thebooksize design. It is activated via binector input p3863 and started after the linecontactor opens and the adjustable delay time (p3862) has expired. The fast dischargeis completed when the line contactor contact closes.NoticePrerequisites for a fast DC link discharge is to use a line contactor with feedbacksignal (p0860) that is controlled via r0863.1.Overview of important parameters (refer to the List Manual) r0108.26 Drive object function module – Braking Module p3860 Braking Module number of modules connected in parallel r3861 BO: Inhibit Braking Module p3862 Braking Module DC link fast discharge delay time p3863 BI: Braking Module activate DC link fast discharge p3864 BO: Braking Module DC link fast discharge p3865 BI: Braking Module pre-alarm I*t shutdown p3866 BI: Braking Module faultFunction diagram overview (refer to the List Manual) 9951 Braking Module interface via CU or parallel circuit4-232© Siemens AG 2006 All Rights ReservedSINAMICS S120 Function Manual, 03/2006 Edition
