Product Description:
The BDS5A-206-00000\406B2-030 is an industrial servo drive produced by Kollmorgen for the BDS Industrial Servo Drives series. It converts the plant’s 230 VAC mains into a regulated DC bus and a pulse-width-modulated output that powers brushless servomotors in positioning or speed-control applications. Command and diagnostic data are exchanged through an RS-232 link, while encoder input provides real-time rotor feedback. The housing is cooled by natural convection, so heat leaves the unit without additional fans. This cooling method supports cabinet layouts where forced airflow is limited or unavailable.
The power stage is designed for a nominal supply of 230 VAC. Its internal bus voltage can range from 225 VDC to 360 VDC, providing the voltage needed by the inverter stage while remaining within the drive’s operating limits. Continuous phase current reaches 6.0 A RMS, allowing the drive to power compatible mid-frame Kollmorgen motors at rated torque. The controller also tolerates short bursts of up to 12.0 A RMS for acceleration or sudden load changes. Current is switched at a carrier frequency of 10.0 kHz, which limits audible noise while keeping switching losses manageable. Internal heat dissipation is rated at 50 W, which helps determine whether passive cabinet airflow can keep component temperatures within acceptable limits.
Feedback precision is supported by a 12-bit converter with 4,096 counts per revolution that digitizes incoming encoder signals for accurate velocity and position control. For machines that use resolver feedback, the drive provides an excitation carrier of 8.5 kHz. The enclosure has a depth of 280 mm, a width of 76 mm, and a height of 340 mm. Its narrow width allows installation in a vertical control-cabinet slot while preserving the depth required for the internal power and control components. The RS-232 connection provides a direct communication path for command and diagnostic information, and the encoder or resolver interface supplies the feedback needed for closed-loop operation.
