Product Description:
The CB06250-2D083M7 is a digital servo amplifier produced by Kollmorgen within the Servostar CD Drives series. Designed as a compact drive, the unit interfaces between a motion controller and a DDR-series servomotor to regulate torque and speed in industrial automation. It accepts AC mains power and provides closed-loop regulation through sine encoder feedback, making it suitable for packaging lines, pick-and-place axes, and general factory handling tasks.
The power stage operates at 230 VAC (325 VDC), and the continuous output limit is 6 A, matching medium-frame direct-drive rotors. Pulse-width modulation at 8 kHz sets the switching frequency for the IGBTs, balancing efficiency with low acoustic noise. The command stage accepts an analog velocity or torque reference from -10 V to +10 V. Its converter processes those signals with 14-bit precision, allowing a fine proportional response to command changes. Internal heat dissipation is limited to 80 W under nominal load, so cabinet ventilation is normally sufficient to remove the generated heat. The amplifier regulates its output according to controller commands and motor feedback, allowing the connected axis to respond accurately as operating loads change.
Protective functions guard both the drive and the connected motor against abnormal operating conditions. An overtemperature trip engages at 80 °C, while an overvoltage threshold of 430 VDC disconnects the DC bus during supply surges. For short acceleration bursts, the current stage can deliver 18 A RMS for up to 500 ms, letting machines overcome static friction without requiring a larger power module. A fault relay rated at 1 A and 24 VDC communicates detected events to external control or safety circuits. The enclosure weighs 4.9 lb (2.22 kg), enabling direct DIN-rail mounting without heavy support brackets. Its compact enclosure also helps conserve space in control cabinets where several motion axes must be installed near their shared power and communication connections.
