Product Description:
The BDS4A-230J-0001\604B2 is a digital servo drive built by Kollmorgen for the BDS Industrial Servo Drives series. It interfaces between a machine controller and three-phase servo motors, supplying precisely modulated power so automated tools can execute accurate position, velocity, and torque commands. By converting power from a regulated DC bus into synchronized AC phases, the unit supports closed-loop motion axes in industrial assembly, packaging, and material-handling equipment. Its control architecture allows the connected motor to respond accurately to changing motion commands and load conditions.
The continuous output current reaches 30 A per phase, allowing the amplifier to provide a continuous apparent output of 11.0 kVA. At its nominal output voltage of 230 VAC, the power stage can momentarily deliver 60 A per phase for acceleration events that require up to 22.0 kVA. The shared DC link must remain between 250 VDC and 360 VDC so the switching devices operate within their permitted conduction range. The drive’s electronic encoder output supplies position data to upstream controls, while the thermal drift of velocity is limited by speed regulation of 0.075% per °C. These electrical characteristics support sustained operation while providing additional current for brief changes in motor demand.
The inverter is designed to control motors that operate at speeds up to 7,500 rpm, while command profiles can reach 8,000 rpm. Pulse-width modulation operates at 10.0 kHz, and power-bus filtering places the ripple frequency at 20.0 kHz to reduce motor heating and audible noise. Resolver feedback is supported with an angular accuracy of 8 arc minutes and an excitation carrier frequency of 7.0 kHz, providing an analog alternative to digital encoder feedback. The resolver signals allow the controller to monitor rotor position and maintain closed-loop command tracking throughout the operating range. The components are housed in a panel-mounted chassis that weighs 9.75 kg, providing a rigid enclosure for the drive electronics.
