Control Techniques SP6402 Overview

The Control Techniques Drive Module SP6402 is a high-performance and versatile drive suitable for a wide range of applications. It is available in two versions: normal duty and heavy-duty, each with different maximum continuous output currents, peak currents, and nominal and motor powers. These products are manufactured in United Kingdom and are designed for Metal production, paper processing, and material conveying usage. They come with a 2-year warranty from MRO Electric. We also carry AC Drives from other manufacturers such as Siemens and Yaskawa.

In the normal duty version, the maximum continuous output current is 236 A, the nominal power at 400 V is 132 kW, and the motor power at 460 V is 200 hp. The peak current is 259 A. This version is suitable for applications that require a moderate level of power and performance.

The heavy-duty version has a maximum continuous output current of 210 A, an open loop peak current of 270 A, a closed loop peak current of 350 A, a nominal power of 400 V of 110 kW, and a motor power of 460 V of 150 hp. This version is designed for heavy-duty applications that require a high level of power and performance.

The Control Techniques Drive Module SP6402 is capable of operating in a variety of modes to suit different applications and requirements. These include an open loop mode, RFC mode, closed loop vector mode, servo mode, and regen mode.

In open loop mode, the drive applies power to the motor at frequencies varied by the user, and the motor speed is a result of the output frequency and slip due to the mechanical load. The drive can use different types of open-loop modes, including open loop vector mode, fixed V/F mode (V/Hz), and quadratic V/F mode (V/Hz), each with its own characteristics and advantages.

RFC mode, or rotor flux control mode, provides closed-loop control without the need for position feedback by using current, voltages, and key motor parameters to estimate the motor speed. It can eliminate instability that is traditionally associated with open-loop control, such as operating large motors with light loads at low frequencies.

Closed loop vector mode is suitable for use with induction motors with a feedback device installed. The drive directly controls the speed of the motor using the feedback device to ensure the rotor speed is exactly as demanded, and the motor flux is accurately controlled at all times to provide full torque down to zero speed.

Servo mode is designed for use with permanent magnet brushless motors with a feedback device installed. The drive directly controls the speed of the motor using the feedback device to ensure the rotor speed is exactly as demanded, and flux control is not required because the motor is self-excited by the permanent magnets that form part of the rotor. Absolute position information is required from the feedback device to ensure the output voltage is accurately matched to the back EMF of the motor. Full torque is available down to zero speed.

Finally, regen mode is a regenerative mode that allows the drive to generate electricity from the kinetic energy of the load when it is decelerating, and feed it back into the power supply. This can help to reduce energy consumption and costs, as well as improve the efficiency of the system.

Overall, the Control Techniques Drive Module SP6402 is a powerful and flexible drive that is suitable for a wide range of applications and operating modes. It offers high performance, reliability, and energy efficiency, making it an excellent choice for demanding environments.
