As a standalone unit, the SOBO® iQ is capable of controlling up to four different hydraulic power units up to 100km away. The SOBO® iQ is meant to be a single control unit for all of the brakes in a single mechanical chain. BRAKING PERFORMANCE In a system without quick release, when a brake open command is received by the SOBO® iQ, the system will activate the pump included in the HPU along with the appropriate valves in order to fill the included accumulators and build the pressure to release the brakes. When quick release is required, the accumulators will already be filled, eliminating the possibility of a delay. The SOBO® iQ also features multiple different startup ramps in order to customize the release of the brakes in the event that it is necessary to allow drives to build up torque during brake release. When a brake command is sent, the SOBO® iQ will begin a predefined braking ramp based on constant stopping time, constant stopping distance, constant braking torque or other braking ramps that can be customized to specialized requirements. Once the SOBO® iQ registers a speed of artificial zero, it will begin a parking sequence that can be defined simply as a complete dump of pressure or as sophisticated as a five segment open loop ramp.
