Product Description:

The PRD-P320260D-C2 from Kollmorgen is a 3-phase frequency inverter servo drive for industrial automation. It runs on 230V and is 2 HP. 3-phase power input is required for stable and efficient power to the drive and motor. 2 HP is the workload the drive can handle, so it’s good for medium-duty industrial applications. The frequency inverter allows for precise control of motor speed and torque by adjusting the frequency of power to the motor. A key feature of the PRD-P320260D-C2 is regenerative capability. This allows the drive to recover energy from the motor during deceleration or braking and feed it back to the power source.

This regenerative process is controlled by specific voltage thresholds: regenerative trip voltage is 390 VDC, and regenerative off voltage is 375 VDC. Below 375 VDC, regeneration is turned off. Energy recovery reduces energy consumption and heat generation. The drive has a 1000-watt regen capability, which is the maximum power it can handle during regen. This is tied to a 100-amp external shunt peak current, which allows the drive to handle high current during regen braking. The external shunt minimum resistance is 4.5 ohms. The drive has a soft start capability. Soft start limits inrush current during start-up to prevent electrical stress on the drive and power supply. Specifically, the soft start surge current is 40 amps, and the charge time is 0.5 seconds. This controlled start-up protects the drive components and extends life.

The drive has 200-watt internal heat dissipation. This is the amount of power the drive dissipates as heat during operation. Good heat management is critical to drive performance and reliability, especially in industrial environments. Environmental considerations are also important for reliable operation. The PRD-P320260D-C2 operates from 0 to 45°C and is suitable for most industrial applications. For storage, it’s -20 to 70°C, so it can be stored in a wider range of environments. These temperature specs ensure the drive can withstand the thermal stresses of operation and storage and prolong its life and reliability.
