Product Description:
The BDS5A-203-00000\102A2-030 is a digital servo drive built by Kollmorgen for the BDS Industrial Servo Drives series. It conditions incoming power, modulates it through high-speed switching devices, and supplies three-phase current to brushless servomotors so that connected axes can follow commanded torque, speed, or position profiles. Within an automation cell, the unit sits between the motion controller and the motor and closes the current loop internally. It also exchanges status data through its RS-232 communication port, providing a compact power stage that supports motor feedback and real-time monitoring.
The drive accepts an input of 230 VAC and rectifies it onto a DC link that can reach 360 VDC while remaining operational down to 225 VDC. Continuous output is rated at 3.0 A RMS per phase, providing 1.2 kVA of sustained output for steady-state loads. The inverter section switches at 10.0 kHz, allowing the current regulator to track rapidly changing commands. Heat dissipation from the switching devices is limited to 35 W, which helps determine the forced-air cooling needed inside the control cabinet. This power arrangement supports continuous axis operation without requiring an oversized ventilation space around the drive.
For short bursts, the amplifier delivers 6.0 A RMS per phase and provides up to 2.4 kVA of output, helping an axis overcome static friction or accelerate a payload quickly. Eight discrete I/O points accommodate overtravel limits, drive-ready signals, and process flags. The resolver input uses an 8.5 kHz excitation signal to acquire rotor position, while an optional encoder input allows the use of digital position feedback. Resolver conversion accuracy is 8 arc-min, and the conversion depth is 12-bit with 4096 counts per revolution. The drive operates at ambient temperatures from 0 °C to 45 °C, supporting full output in typical control enclosures when suitable airflow is provided.
