Safe Brake Control (SBC)
Example of how the function can be used
Example Possible solution
The safe control of a motor holding brake must be
guaranteed in order to guarantee the motor is at a
standstill.
SBC is (if configured) initiated together with
STO. The Motor Module / Safe Brake Relay /
Safe Brake Adapter then carries out the action
and safely controls the outputs for the brake.
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‐
itiated together with
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.
