352 Configuration
Example 2 (with an encoder): The figure below shows an example of the SSE
function with immediate STO set-up when an encoder is used. Configure the safety
encoder interface first (see section Configuring the safety encoder interface on
page 313).
• drive STO is activated immediately after the SSE request
(SSE.13 SSE function = Immediate STO)
• automatic acknowledgement (STO.02 STO acknowledgement = Automatic)
• redundant emergency stop button connected to input
(SSE.11 SSE input A = DI X113:1 & X114:1)
• no outputs connected
• zero speed limit where STO function is completed and it can be acknowledged is
40 rpm (parameter FSOGEN.52 Zero speed with encoder = 40 rpm)
• no brake (SBC.11 STO SBC usage = None).
