Delta's Sensorless Vector Control Drive CP2000 Series has extended the idea of energy saving and uses this principal as the basis of its design. The CP2000 is specifically designed for applications such as air blowers, pumps and HVAC drives with its intelligent PID control providing the greatest efficiency. The Sensorless Vector Control (SVC) offers timely response to load torque increase/decrease which satisfies customer requirements for load changes while enhancing motor performance. A 3-step V/F curve response is used in the variable torque environment to adequately adjust the input voltage and attain the greatest overall performance; this function is especially helpful in pumps and fans applications. It also includes additional functions for operation and protection in variable load environments, such as flying starts, auto-acceleration/deceleration, momentary power loss restarts, auto-tuning, and more. The CP2000 series provides you with the ultimate energy-saving solution for your applications.

A traditional drive system used for inertia load work generally performs rapid deceleration, braking and positioning. When its motor is in generator mode it produces large amounts of regenerative energy that must be consumed to maintain a stable DC bus voltage and safe operation. The traditional method to solve the regenerative energy problem is to install a brake resistor. While it is easy to install and is low cost, it takes up a large amount of space and requires installing additional devices to dissipate the heat. This method provides limited efficiency and wastes the regenerative energy.

Delta's REG2000 series is capable of collecting and converting your system's regenerative energy into reusable electricity for the ultimate in energy savings. The installation process is as simple as installing a brake resistor, but with only half the size and better efficiency. The REG2000 is your best green energy solution for power regeneration.
