Product Description:
The BDS5A-103-00010\202B2-030 is a digital servo drive produced by Kollmorgen as part of the BDS Industrial Servo Drives series. The unit controls brushless servo motors by converting a fixed 115 VAC mains input into a regulated DC link and high-frequency, pulse-width-modulated phase currents. In automated machinery, it supplies precise torque and velocity control, allowing motion controllers to position axes quickly and repeatably. Feedback from compatible resolvers or encoders enables the drive to detect position and speed changes as the motor responds to commands.
The output stage places current-ripple components at frequencies up to 20.0 kHz, keeping most resulting torque ripple outside the mechanical bandwidth of connected equipment. Internally, the pulse-width modulation carrier operates at 10.0 kHz to balance switching losses with current-loop response. Rectified mains power produces a DC bus that operates from 130 VDC to 225 VDC, providing capacity for energy returned during deceleration. At rated load, the inverter supplies 3.0 A RMS and can reach 6.0 A during acceleration. These current levels correspond to 0.6 kVA of continuous apparent power and 1.2 kVA of peak apparent power. The drive dissipates only 30 W at rated operation, helping limit heat buildup inside the control cabinet. Its form factor is no greater than 1.01, indicating near-sinusoidal phase current that helps reduce motor copper losses.
The control section provides 32 I/O lines for start commands, fault reporting, status monitoring, and sequencing with external control logic. A differential encoder input accepts position signals from compatible feedback devices without requiring a separate interface module. The resolver channel excites the rotor at 8.5 kHz and converts the returned analog signals into position data with 12-bit resolution. This feedback arrangement provides an accuracy of 8 arc min, supporting fine indexing in pick-and-place machines and other position-controlled axes. The available input and output lines also allow the drive to exchange operating states and interlock signals with surrounding machine controls. Its single-phase power connection supports installations where three-phase service is unavailable or unnecessary for the required motor output.
