Product Description:

The DSA 030-230-S is a servo amplifier manufactured by Kollmorgen and assigned to the DSA SERCOS Drives series. Designed for closed-loop motion control, this drive conditions power and real-time commands for brushless servomotors in multi-axis industrial automation. By connecting to a fiber-optic SERCOS ring, it receives cycle-synchronized setpoints and returns status, allowing its axis to follow coordinated trajectories in packaging, material-handling, and machining cells. It supports three-phase mains and integrates dynamic energy handling for start-stop duty.

Its power stage uses 3-phase sinusoidal (SVM) commutation to minimize torque ripple while delivering a continuous motor current of 10 A. With a sustained output of 2.0 kW, the unit covers medium-power axes such as feeders or small gantries. Transient demands are satisfied by an output peak of 30 A, whereas the inverter absorbs 100 A inrush on power-up and draws a nominal 18 Arms during steady operation. The current control loop refreshes every 125 µsec, and the velocity loop closes at 250 µsec; these short cycles support stiff regulation across load changes.

The supervisory functions operate on a wider timing frame: the position loop updates every 1 ms, aligning the axis with SERCOS setpoints while still leaving bus bandwidth for up to 32 drives on the same optical ring. During braking, the integrated shunt dissipates up to 51 J per event, and overall heat production is limited to 50 W plus the external resistor, which simplifies cabinet cooling. Eight optically isolated digital inputs, four isolated digital outputs, and a form-C relay rated at 1 A let the controller interface with limit switches, interlocks, or brake release circuits without separate I/O modules. The assembly weighs 2.1 kg, so it can be panel-mounted next to other power electronics without exceeding typical rail loading.
