SERIES 5700 AC CONTROLLERS

Fincor Series 5700 controllers are general purpose, microprocessor based, software-controlled units representing significant advances in AC drive technology. Design features include a comprehensive operator control and programming panel for digital setup, troubleshooting, and self-diagnostics. Additional capabilities include remote interrogation, digital speed input and serial communication for direct control by programmable logic controllers and computers.

The Fincor Series 5700 Controllers offer two methods of motor control:

1. Traditional Space Vector Volts per Hertz (V/F) control

2. Sensorless Torque Control (Encoderless) for improved torque control over the rated speed range.

Fincor Series 5700 controllers provide wide range adjustable speed control of conventional AC induction motors in applications exhibiting a variety of load characteristics. The unit converts the fixed frequency and voltage of the AC line power source to a sine coded pulse width modulated (PWM) adjustable voltage and frequency output that will control induction motors over a wide speed range.

This is efficiently accomplished by a constant potential link coupled inverter system that maintains a uniformly high displacement power factor throughout the speed range without inducing undesirable voltage notch distortion back to the power source.

The power section uses insulated-gate bipolar transistors (IGBT’s) operating at carrier frequencies up to 15 KHz incorporating “soft switching” technology which provides low motor noise, high starting torque, and cool motor operation. The design features of the basic units shown in Figure 1, and available options allow application of the 5700 controllers to numerous industrial applications requiring constant horsepower, constant torque, or variable torque.

Electrical Codes:

Fincor 5700 controllers are designed and manufactured to comply with applicable standards established by the National Electric Code, and NEMA for industrial motor and control equipment. They are UL and Canadian UL listed and CE compliant.
