Fincor Series 5750 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 5750 Controllers offer two methods of
motor control:
- Traditional Space Vector Volts per Hertz (V/F)
control
- Sensorless Torque Control (Encoderless) for improved
torque control over the rated speed range.
Fincor Series 5750 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 5750 controllers to numerous industrial
applications requiring constant horsepower, constant torque, or variable
torque.
Electrical Codes:
Fincor 5750 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. |
