under"Wiring".
4.2.2 Switchingthepowercircuitsonandoff(slowshutdownS35,S36)
Iftheswitchingtimesarenotcritical,theloadsatthepowercircuitscanalsobeshutdown
slowly.Aconnectedbrakeispermittedtohavelongerapplicationtimes,forexample.The
brakeswitcheswithlowernoiseandislowerwearing.
NOTICE
Thepowercircuit'sslowshutdownisnotsafetyrelated.Itmayonlybeused
whenpermittedbythehazardanalysis.
Toshutdowntheinductiveloadsafely,thefastshutdownmustbeactivated
aftertheslowshutdown.Thatwaythebrakehasadualpoleshutdown.
