Fuji Electric FRN0022E2S-4GB variable frequency drive (VFD) is ideal for regulating the speed and torque of an electric motor. It is used in industrial automation, providing precise motor control and energy savings in various applications such as pumps, fans and conveyors.
Working Mechanism:
- The VFD receives AC power which is then converted to DC power by a rectifier, preparing it for further processing.
- The DC passes through a DC bus that contains capacitors; these capacitors stabilise the DC voltage, ensuring its consistency.
- An inverter subsequently converts the stabilised DC back into AC, utilising techniques such as pulse width modulation.
- The AC output, now modified, regulates the motor speed by altering the frequency of the electricity supplied to the motor.
- Sensors continually monitor the motor's performance and send feedback to VFD, enabling real-time adjustments to secure optimal operation across various load conditions.
Features:
- It features a NEMA 1 enclosure for protection against dust and indirect moisture.
- This variable frequency drive has programmable start / stop control to optimise the start-up and shut-down of connected motors.
- It comes with dynamic braking to rapidly decelerate the motor using the drive's energy for requiring quick stops.
- This variable frequency drive offers an LED for clear, bright readouts of operational data and settings for easy monitoring even in low-light conditions.
Frequently Asked Questions:
Q. How do adjustable acceleration and deceleration times contribute to customising the Variable Frequency Drive?
A. Adjustable acceleration and deceleration times allow users to customise the speed at which the motor ramps up or down. This customisation is essential for adapting the drive to specific operational needs and preventing sudden jolts or stops.
Q. How does the VFD process input control signals and contribute to integrating external control?
A. The VFD accepts input control signals through remote contacts, providing flexibility for external control integration and seamless integration with other systems or external controllers for coordinated operation.
Q. How to control this three phase 5.5 / 7.5kW electric inverter?
A. It features a remote keypad allowing for flexible, user-friendly operation away from the drive's physical location.
Q. Is Fuji Electric FRN0022E2S-4GB variable frequency drive protected from unauthorised usage?
A. It features password lockout to prevent unauthorised access to configuration settings, ensuring operational security.
Q. What factors should be considered while selecting a VFD?
A. Major factors include motor horsepower, voltage & current ratings, enclosure type, communication protocols and application requirements.
