Product Description:

The CE10260 servo drive is produced by Kollmorgen within the CD Servostar CD Drives series. It is an AC line-powered amplifier that regulates torque, speed, and position of brushless servo motors on automated machinery. By processing real-time commands from a motion controller and closing control loops with encoder feedback, the drive supplies conditioned power to the motor while isolating sensitive control electronics from the main three-phase network. This arrangement lets the unit handle motor commutation, feedback evaluation, and power conversion in one compact drive package for positioning, indexing, and coordinated axis motion.

It accepts a 3.5 kVA continuous load and can deliver a 10 A RMS output to the motor windings. The input side is wired for 230 VAC three-phase power, which the front-end rectifier converts to a 325 VDC bus for the IGBT stage. High-frequency modulation at 8 kHz reduces current ripple and acoustic noise, while the current loop updates every 62.5 µs to track commanded torque with minimal lag. That DC bus feeds the output stage with tightly controlled switching pulses, which helps the motor respond smoothly during speed changes and load disturbances. Under nominal conditions, internal heat loss is limited to 132 W, and the logic section runs from a standard 24 VDC control supply.

The velocity regulator updates every 250 µs, while the position loop executes every 500 µs, giving the controller the timing needed for coordinated multi-axis motion. To protect the power electronics, the thermal sensor initiates a shutdown at 80 °C core temperature, and the drive disables gating if the DC bus rises to 430 VDC or falls below 90 VDC. These protective actions help the unit stop motor output quickly during regeneration, incoming line disturbances, or abnormal heating. The loop timing also supports stable tracking when commanded motion changes rapidly, which is important in machines that depend on repeatable acceleration, deceleration, and position correction.
