How to configure SBC before STO
For more information on the SBC before STO function, see page
.
Example 1 (without an encoder):
The figure below shows an example of the SBC
before the STO set-up when an encoder is not used:
• STO delayed brake with negative delay -500 ms

• redundant emergency stop button connected to input
DI X113:1 & X114:1
)
• automatic acknowledgement (

)
• estimated time in which the motor brakes to a stop from the maximum speed:
1200 ms (

)
• brake connected to redundant output, diagnostic pulses activated

= DO X113:7 & X114:7)
• STO is activated if brake feedback fails (

• brake feedback input connected to input
=
DI X113:2
)
• feedback input type NC (inverted state compared with the brake relay)
=
Mechanically linked NC contacts
).
