The Fuji Electric FVR1.5AS1S-4E (1.5kW / 2.0 HP) serves the same primary purpose as the smaller models but is engineered to handle the higher electrical demands of a 2-horsepower motor (rated at 4.2 Amps).

Primary Control Functions

Precision Speed Regulation: Controls motor speed by varying frequency from 0.1 to 400 Hz.
Enhanced Torque Performance: Utilizes Dynamic Torque Vector Control to provide a high starting torque (150% or more at 5Hz). This is crucial for 2 HP motors starting under load, such as fully loaded conveyors or heavy-duty fans.
Energy Optimization: Automatically adjusts the voltage-to-frequency (V/F) ratio to ensure the motor consumes only the power it actually needs for the current load.

Key Operational Features

PID Control for Automation: Can automatically maintain a set pressure or flow rate (common in pumping systems) without needing an external controller.
8-Step Speed Control: Allows you to program up to 8 different speeds that can be triggered by external switches or a PLC.
Slip Compensation: Monitors the load and compensates for motor "slip" to keep the RPM consistent even when the mechanical load changes.
Quick-Stop Deceleration: Features controlled braking to stop heavy 2 HP rotating masses quickly and safely.

Protection & Safety Functions

Because this unit handles higher current (4.2A), its protection functions are vital:

Advanced Overload Protection: The built-in electronic thermal relay is specifically calibrated for 1.5kW motors to prevent winding burnout.
Stall Prevention: If the motor draws too much current during acceleration, the drive will automatically slow down the ramp-up to prevent a "trip" or motor stall.
Fault Logging: Stores details of the last few error codes (like Overcurrent or Overvoltage) to help you troubleshoot mechanical jams or power issues.

Technical Interface

Keypad Control: Includes a physical potentiometer (dial) for immediate manual speed control.
Digital/Analog I/O: 6 digital inputs, 2 analog inputs, and 2 output signals (Relay/Transistor) for status monitoring (e.g., "At Speed" or "Fault").
Communication: Integrated RS-485 (Modbus RTU) for remote monitoring via a computer or PLC system.
