332 Configuration
Example 2 (with an encoder): The figure below shows an example of a simple STO
function set-up when an encoder is used. Configure the safety encoder interface first
(see section
Configuring the safety encoder interface on page 313 ).
• redundant emergency stop button connected to input
( STO.11 STO input A = DI X113:1 & X114:1)
• automatic acknowledgement ( STO.02 STO acknowledgement = Automatic)
• 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 )
• the fly-start feature is in use, that is, you can restart the drive before the motor has
stopped ( STO.13 Restart delay after STO = 1000 ms )
• no output connected
• no brake (
SBC.11 STO SBC usage = None ).
