Comparison Sheet SOBO® iQ Control & Proportional/Digital Brake Control System Below highlights some of the main differences between the SOBO® iQ and a Proportional/ Digital Brake Control System SOBO® IQ CONTROL PROPORTIONAL (ANALOGUE) AND DIGITAL CONTROL REACTION TIME RELEASED BRAKES TO BALANCE PRESSURE OPERATIONAL STATUS W/ MAIN ACCU FAILURE SOBO® iQ Ramp still available with additional “noise” in stopping ramp Limited Control ACCUMULATOR SIZE Small accumulators can be utilized due to valve design Large accumulators required due to valve design Even across all brakes since all brakes operate simultaneously Uneven across brakes due to dedicated digital vs proportional control brakes (digital brakes incur much greater pad wear) Predictable/consistent air gap adjustment due to even pad wear since all brakes operate simultaneously More frequent air gap adjustment due to excessive wear on digital brakes (more frequent shutdowns required) INDIVIDUAL CALIPER STRESS/FATIGUE Brake Caliper stress is split evenly between all calipers since all brakes operate simultaneously Brake Caliper stress is much higher on digital calipers since they are applied with full force every time they are activated LOAD ACROSS INDIVIDUAL BRAKE DISCS Easily balanced by arrangement of calipers (eg one caliper at 3 and 9 o’clock) Individual Discs cannot be balanced practically LOAD ACROSS ALL BRAKE DISCS Easily balanced by arrangement of calipers (eg one caliper at 3 and 9 o’clock on all discs) Multiple Discs cannot be balanced practically due to uneven application of digital calipers MECHANICAL SHOCKWAVE Shockwave introduction during braking is kept to a minimal level due to SOBO® iQ Programming and all brakes operate simultaneously Shockwave introduction from proportional calipers is minimal but shockwave introduction from digital calipers cannot be controlled/minimized BRAKE SYSTEM PROGRAMMING INTEGRATION WITH MAIN PLC Very simple integration with few communication signals exchanged. All brake system programming is included in the Svendborg Brakes SOBO® iQ controller. Heavy integration between brake system and main PLC is necessary. Brake system programming is typically supplied by parties other than the brake manufacturer.
