Product Description:
The BDS5A-103-01010-102A-2-020 servo drive is produced by Kollmorgen within the BDS Industrial Servo Drives series. Designed for precision motion systems, the unit converts a regulated DC supply into sinusoidal phase currents that govern a brushless motor. In industrial automation, it provides closed-loop speed and torque control for indexing tables, pick-and-place axes, and similar electromechanical stages, linking directly to PLCs through its differential serial port.
During continuous duty, the drive supplies 3.0 A (RMS/phase), and this output is sustained while the DC bus remains between 130 VDC and 225 VDC. At a nominal bus level of 160 V, the power stage can deliver 0.6 kVA of apparent power to the motor windings. Pulse-width modulation occurs at 10 kHz, a switching rate that keeps current ripple low and minimizes audible noise. Internal losses produce 30 W of heat, so cabinet airflow must extract that heat to maintain the proper component temperature. Because the semiconductor devices operate in an inverter topology, the bus thresholds establish undervoltage and overvoltage shutdown limits that protect both the drive and the connected motor. These protections interrupt operation when the incoming DC supply moves outside the permitted range.
Short bursts are handled by a peak capability of 6.0 A for 2.0 seconds, permitting quick acceleration without oversizing the drive. Machine-level coordination is aided by 32 points of discrete I/O that map to limit switches, status lamps, or user interlocks. Integrated resolver-to-digital conversion achieves 8 arc-min positioning accuracy with a feedback resolution of 12 bits (4096 counts/rev), allowing tight following-error limits in servo loops. Command and diagnostic data pass over an RS-422/RS-485 interface, supporting control integration without extra gateways. This communication link supports parameter tuning, fault reporting, and configuration updates from a supervisory controller.
