About FVR0.75AS1S-4E - Fuji Micro 0.75 KW 440V

The FVR0.75AS1S-4E is the next size up in the Fuji Electric FVR-Micro series. It shares the same voltage class and features as the 0.4kW model you were looking at, but with higher power capacity.

Technical Specifications (Comparison)

Feature	FVR0.4AS1S-4E (Previous)	FVR0.75AS1S-4E (Current)
Motor Capacity	0.4 kW (0.5 HP)	0.75 kW (1.0 HP)
Input Voltage	3-Phase 380V480V	3-Phase 380V480V
Rated Output Current	1.5 A	2.5 A
Overload Capacity	150% for 1 min	150% for 1 min

Key Differences to Note

Power Output: This unit is rated for a 1.0 HP motor. Using it on a 0.5 HP motor is fine (oversizing), but you must adjust the Electronic Thermal Overload parameters to protect the smaller motor.
Heat Dissipation: Because it handles more current (2.5A vs 1.5A), it generates slightly more heat. Ensure your enclosure ventilation can handle the extra thermal load.
Wiring: The terminal block is the same, but you should ensure your power cables and fuses are rated for the higher 2.5A output.

The

Fuji Electric FVR0.75AS1S-4E

(0.75kW / 1.0 HP) functions identically to the 0.4kW model but with a higher current capacity (2.5A) to handle more powerful motors.

Primary Control Functions

Speed & Torque Management: Uses Sensorless Vector Control and Dynamic Torque Vector Control to maintain precise motor performance and high torque (150% or more) even at low speeds (starting at 1Hz or 5Hz).
PID Control: Features a built-in PID regulator for automated control of process variables like pressure, temperature, and flow rate for fans and pumps.
Multi-Step Speed: Supports up to 8 to 16 preset speed stages using 3-bit external digital signals.
Energy Optimization: Includes algorithms specifically designed to minimize motor loss and reduce overall power consumption.

Advanced Operational Modes

Jog Operation: Allows for manual "inching" of the motor for machinery positioning or maintenance.
Auto-Restart: Automatically restarts the motor after an instantaneous power failure.
Pattern Operation: Enables automatic operation/stop sequences based on a set pattern.
Slip Compensation: Improves speed regulation by automatically adjusting the output frequency based on the load, which shortens settling times.

Safety & Protection

Hardware Protection: Includes overcurrent, overvoltage, undervoltage, and overheating safeguards.
Diagnostics: Records an alarm history of the latest 4 to 6 faults for easier troubleshooting.
Stall Prevention: Automatically adjusts current during acceleration or heavy loads to prevent the motor from stalling.

I/O Capabilities

Inputs: 6 Digital inputs and 2 Analog inputs (0-10V, 4-20mA) for remote control.
Outputs: 1 Transistor and 1 Relay output for status signals like "Running" or "Frequency Arrival".
Communication: Standard RS-485 (Modbus RTU) port for networking with PLCs and other industrial controllers.
