Product Description:

The CE03561 servo drive is produced by Kollmorgen as part of the CD Servostar CD Drives series. Classified within the Compact Drive product family, this unit supplies controlled three-phase power to brushless motors so that speed, torque, and position loops in automated machinery remain consistent with commanded profiles. By accepting a separate 24 V logic supply, the drive keeps its control electronics active during safety events, allowing devices on a SERCOS network to maintain communication even when the main bus voltage is removed. This helps the controller retain diagnostics and status reporting during controlled shutdowns.

Its DC link operates at a nominal bus voltage of 325 VDC, a level chosen to match rectified 230 V mains while leaving headroom for regenerative energy. The continuous output stage supports a rated current of 3 A, making the drive suitable for low-to-mid power axes in packaging or electronics assembly. Pulse-width modulation occurs at 16 kHz, and the high carrier frequency improves current resolution while lowering audible noise in the connected motor. For short acceleration bursts, the inverter can deliver 6 Arms for two seconds and a higher reserve of 9 Arms for 500 milliseconds, giving extra torque without exceeding thermal limits. Internally, 60 W of power is dissipated as heat, while protective trips monitor temperature, overvoltage, and undervoltage thresholds.

The drive’s commutation logic supports field-oriented control up to 400 Hz electrical frequency, allowing operation with high-speed servo motors. Current regulation is refreshed every 62.5 µs, so torque commands track load changes with minimal delay. Thermal shutdown is fixed at 80 °C on the heatsink, and an overvoltage trip engages at 430 VDC to protect the DC bus capacitors. Additional safeguards include an undervoltage limit of 90 VDC, and the SERCOS interface reports fault codes and axis status to the controller.
