The

Fuji Electric FVR0.4AS1S-4E

is a Variable Frequency Drive (VFD) designed to control the speed and torque of three-phase induction motors. It is commonly used in small-scale industrial applications like pumps, fans, and conveyor systems.

Primary Functions

Variable Speed Control: Regulates motor speed by adjusting the output frequency from 0.1 to 400 Hz.
High Starting Torque: Provides over 150% torque at low speeds (5Hz), ensuring stable operation even for heavy-start loads.
PID Control: Built-in PID functionality allows for automated control of temperature, pressure, and flow rates.
Energy Efficiency: Uses advanced control algorithms to minimize motor losses and optimize power consumption.

Operational Features

Multi-Step Speed: Supports up to 16 pre-set speed stages using digital inputs.
Flexible Frequency Setting: Can be adjusted via the built-in keypad potentiometer, analog inputs (0-10V or 4-20mA), or RS-485 communication.
Jog Operation: Allows for short, manual motor bursts to assist with machine positioning or testing.
Auto-Restart: Includes a function to restart the motor automatically after an instantaneous power failure.

Protection Functions

The drive monitors performance to prevent damage through several built-in safety features:

Overcurrent & Short-Circuit: Stops the inverter if it detects a spike in current or a short on the output side.
Overvoltage & Undervoltage: Protects the internal DC bus from voltage fluctuations.
Electronic Thermal Relay: Provides overload protection for the motor without needing external relays.
Stalling Prevention: Adjusts output to prevent the motor from stalling during sudden load changes.
