How does SBC function in detail?
The inverter detects the selection of STO using a fail-safe input.
The inverter then safely switches off the torque of the connected motor.
SBC is (if configured) initiated together with STO. The Motor Module / Safe Brake Relay / Safe
Brake Adapter then executes the action and safely controls the outputs for the brake.
