Product Description:
The BDS5A-106-01010\03011A2-030 is a digital servo drive manufactured by Kollmorgen for the BDS Industrial Servo Drives series. It converts single-phase mains power into controlled three-phase output power, providing torque, velocity, and position regulation for automated machinery. The unit supports resolver feedback and communicates with motion controllers, enabling precise indexing in feeders, small gantries, and labeling heads. Its compact chassis allows installation inside distributed cabinets where thermal capacity and wiring space are limited.
The control board connects to PLCs through an RS-422/RS-485 serial port and provides 32 optically isolated I/O points for local sequencing. During continuous operation, the power stage delivers 6.0 A RMS per phase, providing a sustained output of 1.2 kVA at the motor terminals. This current is supplied by a DC bus that can rise to 225 VDC when the incoming mains voltage is at its nominal level. The bus is filtered to limit current ripple, while a carrier frequency of 20.0 kHz helps reduce audible noise. Torque commands are applied at a PWM frequency of 10.0 kHz to keep harmonic energy away from mechanical resonances. An encoder input verifies motion, a resolver channel is energized at 8.5 kHz, and the resolver-to-digital converter maintains an accuracy of 8 arc-minutes. Internal power losses are limited to 40 W, which reduces the cooling demand within the cabinet.
For rapid indexing, the inverter can briefly supply 12.0 A RMS per phase, corresponding to a peak output of 2.4 kVA within its short-term operating capacity. Startup charging begins after the 115 VAC line is rectified. If the line voltage drops, the DC rail may fall to its 130 VDC minimum while the control logic remains active. Position resolution reaches 12-bit resolution with 4,096 counts per revolution, supporting fine registration on tensioning rollers and small rotary axes. Status words are transmitted over the serial bus, allowing the system controller to respond quickly to overcurrent or undervoltage events.
