Product Description:
The BDS4A-240J-0001\604C2 is an industrial servo drive manufactured by Kollmorgen for the BDS Industrial Servo Drives series. The unit converts power from the common DC link into controlled three-phase currents that accelerate and brake brushless servo motors used in automated assembly cells, conveyors, and process equipment. Integrated resolver decoding, encoder pass-through, and fault monitoring make the drive a compact interface between a motion controller and the motor while supporting continuous operation in cabinet environments.
The drive delivers a continuous phase current of 40 A RMS, enabling medium-frame servomotors to hold rated torque without overheating. With a 330 VDC link, it sustains a continuous apparent power of 14.5 kVA, providing capacity for multi-axis systems. Line conversion yields a nominal output of 230 VAC at the motor terminals, produced by pulse-width modulation at 10.0 kHz; this carrier frequency balances audible noise and switching losses. For acceleration, the amplifier can source a peak current of 80 A RMS per phase. Feedback handling includes a resolver decoder with 8 arc-minute accuracy and 7.0 kHz excitation, plus an electronic encoder output for position retransmission. The aluminum chassis measures 140 mm wide, 340 mm high, and 284 mm deep for IEC panel mounting.
During short transients, the converter delivers a peak apparent power of 29 kVA, supporting high-inertia starts without saturating the DC link. Normal operation produces 335 W of heat that must be removed by cabinet airflow or heat sinks. Internal filtering limits motor current ripple at a switching frequency of 20.0 kHz, reducing torque pulsation. The power stage tolerates a DC bus voltage up to 360 VDC and remains active down to 250 VDC, allowing operation from rectified mains with fluctuating input. Bus capacitors support the power stage during load changes, while fault logic trips the drive when voltage or current exceeds the established limits. These protective functions help prevent electrical overstress during demanding industrial operating cycles.
