signal to control a holding brake."
Example of how the function can be used
Example
The safe control of a motor holding brake must be
guaranteed in order to guarantee the motor is at a
standstill.
How does SBC function in detail?
The converter recogni‐
zes the selection of
STO via a failsafe input
or via the safe commu‐
nication PROFIsafe.
The converter then
safely switches off the
torque of the connected
motor.
SBC is (if configured) in‐

STO. The Motor Mod‐
ule / Safe Brake Relay /
Safe Brake Adapter
then carries out the ac‐
tion and safely controls
the outputs for the
brake.
