Description

ABB DSQC612(3HAC15639-1)Product Overview In industrial robot systems,the IRC5 controller is the”command center,”and the ABB DSQC612(3HAC15639-1)is the”core brain”of this command center—the key circuit board responsible for translating the robot’s motion commands into actual control signals!Whether it’s a robot on an automotive welding line precisely aligning with solder joints,or an assembly robot in an electronics factory meticulously grasping parts as thin as 0.1mm,it relies on this circuit board to calculate motion trajectories and coordinate the movements of servo motors and I/O modules.Without it,the robot would be like a”headless fly,”unable to move at all.Those of us in robot maintenance know that the stability of the circuit board directly determines whether a robot can work,and the ABB DSQC612(3HAC15639-1)excels in this regard.The dual-power supply design(5V logic power+12V analog power)ensures that even with minor voltage fluctuations on one supply,the core circuitry can still operate normally on the other.Furthermore,it isolates analog and digital signals,making it less susceptible to interference from motors and voltage surges in the workshop.For example,a customer had a welding robot working next to a high-power welding machine;the ABB DSQC612(3HAC15639-1)still maintained welding accuracy within 0.2mm,significantly more stable than other brands of robots in the same workshop.Even more conveniently,this board is compatible with all IRC5 controllers,from older IRC5 Single models to newer IRC5 Compact models.Simply remove the old board,insert the ABB DSQC612(3HAC15639-1),and re-flash the firmware to use it.A customer’s robot,used for 8 years,frequently reported faults on its old circuit board.After replacing it with an ABB DSQC612(3HAC15639-1),not only did the faults disappear,but the robot’s motion response also improved by 10%.ABB’s original circuit boards truly offer reliable performance!Key Features and Advantages:Precise Motion Control,Robot”Mill-Sized”:The ABB DSQC612(3HAC15639-1)features a built-in high-precision motion control chip capable of calculating motion trajectories at the 0.01mm level.Combined with ABB’s servo drive system,the robot’s repeatability can reach±0.05mm.Previously,an automotive parts customer used it with a welding robot to weld 2mm thin steel plates.The robot’s welding torch positioning error never exceeded 0.1mm,resulting in very smooth welds.The product qualification rate increased from 96%to 99.8%,significantly reducing rework costs.Moreover,it supports multi-axis linkage control,allowing 6-axis robots to move simultaneously without conflict,and it can handle complex curved surface welding.Stable and reliable,with very few faults:The ABB DSQC612(3HAC15639-1)boasts an MTBF exceeding 400,000 hours,equivalent to 45 years of continuous operation without failure,twice the lifespan of many third-party circuit boards.One electronics factory’s assembly robots operate 24/7,and the ABB DSQC612(3HAC15639-1)ran continuously for 6 years without a single circuit board failure,requiring only periodic dust removal maintenance.Furthermore,it has built-in fault diagnosis capabilities;if there are abnormal signals or unstable power supply,it will issue an early alarm in RobotStudio,preventing sudden shutdowns and allowing maintenance personnel to troubleshoot in advance,avoiding downtime losses.High compatibility,upgrades”without major modifications”:The ABB DSQC612(3HAC15639-1)is a”universal board”for IRC5 controllers.Regardless of the year the customer’s controller was purchased,as long as it’s an IRC5 series controller,it can be used immediately without changing the control cabinet or modifying the robot program.One customer,who was using a 2015 IRC5 Multimove controller and wanted to upgrade the robot’s control precision,purchased the ABB DSQC612(3HAC15639-1).The old board was removed,the new board installed,and the firmware flashed—all done in 2 hours,and production resumed the same day.If a different brand of board had been used,system adaptation would have been required,resulting in at least 3 days of downtime and prohibitively high costs.Strong anti-interference,”unrestricted by workshop environment”:Many interferences in industrial workshops?The ABB DSQC612(3HAC15639-1)is not afraid at all!It isolates analog circuits(such as servo signals)and digital circuits(such as logic signals)with 150V AC,so even if there are high-power motors or welding machines nearby,it will not affect the board’s operation;moreover,its power supply end has surge protection,so sudden voltage fluctuations in the workshop will not burn out the board.There is a robot in a metallurgical plant,installed not far from the blast furnace,where the voltage fluctuates frequently,but the ABB DSQC612(3HAC15639-1)still operates stably without ever experiencing a single misalignment due to interference.​
