Product Description:
The CB06550 servo amplifier is supplied by Kollmorgen as part of the CD Servostar CD Drives series. It functions as a compact drive that delivers closed-loop current, velocity, and position regulation for brushless motors used in packaging stations, pick-and-place modules, and other industrial axes. By embedding real-time control hardware inside a narrow housing, the unit allows machine builders to reduce cabinet depth while retaining an analog command interface for connection to standard motion controllers. Its control architecture supports precise motor response across positioning, speed-control, and torque-control applications.
The control interface is analog, so the drive accepts demand signals through a ±10 V differential pair and digitizes the commands with a resolution of 14 bits. The input path accepts a full-scale range of ±10 V and includes protection against voltage transients. Torque is regulated by a current loop that refreshes every 62.5 µs, enabling an accurate response to high-bandwidth motion profiles. Motor excitation is generated with an 8 kHz pulse-width modulation frequency, which reduces current ripple while keeping switching losses within the internal dissipation limit of 80 W. During rapid acceleration, the power stage can deliver up to 18 A for 500 ms before returning to the continuous current level. A sine encoder feedback channel reports rotor position to the control circuits. A dedicated logic supply powers the control electronics independently of the main DC bus.
The amplifier has a 2.8 kW input rating and delivers an output of 2.2 kW, with most of the power difference dissipated as heat through the mounting plate. Steady-state phase current remains at 6 A, while protective circuits monitor the supply, current level, encoder signals, and operating temperature. The power stage disconnects when the DC link rises above 430 VDC or drops below 90 VDC. Thermal protection also shuts down the power stage when the heat sink reaches 80 °C. These protective thresholds help prevent damage during abnormal supply conditions, excessive loading, or inadequate heat transfer. With a weight of 2.22 kg, the module can be installed on a DIN rail or bulkhead without additional bracing.
