Parameterizing The Digital Input For Ss1 Off3 - Siemens SINAMICS DCM User Manual

Introduction

1.9 Parameterizing the digital input for SS1 OFF3

1.9 Parameterizing the digital input for SS1 OFF3
Digital input DI/DO 4 (terminal X177.15 on the CUD electronics module) of the SINAMICS
DC MASTER must be used for the SS1 function. This digital input must be parameterized so
that signal OFF3 (fast stop) is controlled in all of the command data sets (CDS) used
Setting p849 (OFF3) p53010[8] (DI/DO 4)
Setting p50296 (OFF3 down ramp) e.g. 5 seconds
Note
For setting p50269=0 (OFF3 ramp down time), the drive brakes at the current limit. The
actual ramp-down time is influenced by the driving forces of the mechanical system. The
safety relay delay should be set longer than the actual ramp-down time.
