Product Description:

The CE03250 servo drive is produced by Kollmorgen within the CD Servostar CD Drives series. As a member of the Compact Drive family, it conditions DC bus power, modulates current, and accepts encoder feedback to regulate brushless motors in factory automation. The unit interfaces with machine controllers through a standard logic input and supplies controlled three-phase output to motion axes, providing a scalable platform for medium-power positioning tasks. With its narrow housing, it can be panel-mounted alongside other amplifiers and supports dense cabinet layouts common in packaging and material-handling equipment.

Its nominal bus voltage of 325 VDC sets the operating energy level for the internal IGBT bridge, while a carrier frequency of 16 kHz is used to reconstruct sinusoidal phase currents and minimize audible noise. The drive can deliver a peak phase current of 9 Arms for short accelerations and maintains a continuous rated current of 3 A during steady motion. For safety interlocking, the relay fault contact is rated for 1 A, and incoming mains are protected by a 10 A line fuse. Standard hardware keeps the control electronics energized when the power section is isolated. Quadrature encoder feedback is processed for closed-loop velocity and position control. Housing dimensions are 244.0 mm high, 67.3 mm wide, and 163.0 mm deep, allowing installation on DIN rail or a backplate.

Thermal and voltage safeguards complete the protection scheme. An internal sensor trips the drive at 80 °C, and the bus link is disconnected if DC voltage rises above 430 VDC or falls below 90 VDC. During normal operation, the power devices shed approximately 60 W as heat, requiring convection or forced-air cooling inside the cabinet. The aluminum enclosure weighs 1.61 kg, and the compact form supports placement in densely packed control panels without obstructing airflow.
