Product Description:
The BDS5A-220-40110\617F4-032T is a digital servo drive supplied by Kollmorgen within the BDS Industrial Servo Drives series. Designed to regulate three-phase brushless motors in automated machinery, the drive converts incoming electrical power into controlled PWM output that governs speed, torque, and position loops. In factory lines, it acts as the motion-axis amplifier, receiving program commands from an upstream controller and delivering high-bandwidth current to the motor windings. The unit’s compact chassis and standard mounting pattern allow it to fit into control cabinets without consuming excessive rack space.
During sustained operation, the drive can deliver a continuous motor current of 20.0 A while drawing a continuous apparent power of 8.0 kVA. For transient moves or rapid acceleration, output rises to a peak of 40.0 A, and the power stage supports up to 16.0 kVA for short intervals. The IGBT bridge is modulated at 10.0 kHz, a switching rate that balances acoustic noise and current ripple. A ripple suppression network tuned to 20 kHz minimizes DC bus oscillations. Internal fans move cabinet air and consume 0.2 A, while the thermal design keeps semiconductor temperatures within their rated limits. Command references enter through an analog input channel, and the logic board interprets 8-bit ASCII words with no parity for local diagnostics. Physical wiring terminates on a male DB-9 connector.
A resolver interface provides position feedback, and its carrier is excited at 8.5 kHz to support precise angular processing. Host communication occurs through an RS-232 link, allowing software to read status words and adjust tuning parameters. For machine control, the front panel routes up to 32 I/O signals that can be assigned to limit switches, drive-ready contacts, or fault outputs. The enclosure has a thermal load of 150 W, so the panel must provide sufficient airflow or heat dissipation to sustain rated output without derating. These communication and feedback channels allow the upstream controller to monitor drive conditions while the resolver supplies continuous rotor-position data. Assigned inputs and outputs can coordinate external machine signals with the drive’s operating state.
