The Kollmorgen CP310250 is a servo drive in the PD Servostar Servo Drives series with a continuous power rating of 3.6 kW and a rated output current of 10 A RMS per phase. It accepts 190-230 VAC three-phase input and operates with a nominal DC bus voltage of 270-320 VDC. The drive is designed with dimensions of 264 by 90 by 202 mm and supports a Delta Tau PMAC2 controller interface.
Internal Product Review
The CP310250 is a Kollmorgen PD Servostar servo drive with a 190-230 VAC 3-phase line input and 3.6 kW continuous power. Delta Tau PMAC2 interfacing and direct digital PWM input support clean integration in motion control architectures. Peak output to 20 A RMS/phase for 2 s gives this drive strong transient handling and a very capable performance profile.

Product Description:
The CP310250 servo drive from Kollmorgen belongs to the PD Servostar Servo Drives series. As a closed-loop amplifier, it converts three-phase mains power into controlled output for brushless servomotors while coordinating torque and speed commands from a motion controller. In automated machinery, the unit sits between the PLC-level controller and the motor, regulating current, monitoring feedback, and protecting the axis during dynamic production cycles.
The drive accepts a three-phase input of 190–230 VAC, which is internally rectified to a DC bus maintained between 270–320 VDC. This bus acts as the energy reservoir for the pulse-width-modulated outputs. The drive can deliver continuous mechanical power of 3.6 kW when the output current remains at the rated 10 A RMS per phase. For rapid acceleration or disturbance rejection, the current regulator allows peaks of up to 20 A RMS per phase for the permitted interval. An overvoltage trip engages at 430 VDC to protect internal components from excessive DC-bus voltage. These electrical limits support drive selection based on motor torque constants and line regeneration levels.
The front-panel interface communicates with a Delta Tau PMAC2 controller through a 36-pin Mini-D connector, and current feedback is transferred as serial digital information for the U and V phases. Control logic is powered by an internal 8 VDC rail, while external devices can draw an analog supply of ±15 VDC for sensor excitation. The peak-current window lasts 2 seconds, so the connected motor must tolerate the resulting short-term heating before returning to a continuous load. Safe ambient operation is limited to 0 to 45 °C; outside this range, drive derating or additional cooling is required. The enclosure measures 264 × 90 × 202 mm, so the cabinet must provide sufficient room for airflow around the heat sink. The installation must also allow access to the pulse-width modulation and PMAC2 interface connections.
