Svendborg Brakes Introduces the Latest Controlled Braking Technology for Mining Conveyor Applications

Svendborg Brakes recently introduced SOBO iQ, the next generation of their industry-leading SOBO (Soft Braking Option) braking controller. The state-of-the-art SOBO iQ combines various cutting-edge technologies to provide significant flexibility, safety and durability on heavy-duty mine conveyors.

The SOBO iQ features three-state digital modulation, an industry first in a braking system, and a revolutionary dual-loop PI control (pressure/speed). The pressure control is based not only on speed but also on deceleration. SOBO iQ controls braking torque by comparing a preset speed ramp with actual conveyor speed feedback. The unit can provide different braking profiles for different operational scenarios. Advanced functions including independent overspeed monitoring, rollback, gearbox and out-of-band monitoring are included.

The SOBO iQ provides only the torque needed for a safe, controlled stop. The new controller can be used with a combination of brake types, mounted on both the high and low speed sides of the conveyor drive. Up to 4 HPUs can be connected to each controller. The new iQ is four times faster than previous generations and features failsafe hardware based on 2-stage backup, and a defined communication failure behavior. Remote access is possible and an optional touch screen is available for setup and monitoring.

Designed for tough mine installations, the controller utilizes an industrial-grade embedded PC, a built-in MODBUS TCP/IP interface, a custom optimized IP67 communications module, and an EtherCAT-based internal network with full BUS monitoring and optional cable redundancy.
