Fuji Electric frequency inverter FVR-Micro (S1) series has a high starting toque of 150% or more

Achieving powerful operation even at low speeds. (when slip compensation control is ON, and when running at 5Hz or more.)

Continuous operation using the restart function for instantaneous power failure

During an instantaneous power failure, it is possible to automatically restart operation after restoring power. You can select between a mode that restarts operation at the frequency when the power failure occurred or a mode that restarts operation at the starting frequency from operation startup.

Fuji Electric drive FVR-Micro (S1) series has a Stable operation even for step load

The slip compensation function permits stable operation even when the motor load fluctuates (step load).

Stable operation even at low speeds

The rotational unevenness even at low speeds (5Hz) is the same level as the FRENIC-Mini which is the higher rank compact model of FVR-Micro.

Energy savings effect by Fuji Electric inverters FVR-Micro (S1) series

- You can save a significant amount of electric power by controlling the inverters when operating fans and pumps, as compared to damper (valve) control.
- Especially when the air flow (flow rate) is low, the energy saving rate increases significantly.

Compatible with wide range of frequency settings

The optimum frequency setting method can be selected to match your machine or equipment.
Settings are performed by keypad operation, analog input (4 to 20mA, 0 to +10V, 0 to 5V, 1 to 5V), or multistep speed settings (8 steps) etc.

A transistor output and a relay output are respectively provided to Fuji Electric frequency inverter FVR-Micro (S1) series

This enables information signals such as running, frequency arrival, ready to operation signals to be output. 

The output frequency can be set to a maximum of 400Hz

The inverter can be used for equipment that requires a high motor speed such as centrifugal separator. (In this case, check the operation in combination with the motor.)

Non-linear V/f pattern setting is possible.

One point for the non-linear V/f pattern, which can be set as desired, has been added, and so the V/f pattern can be adjusted to match the application.

Fuji Electric drive FVR-Micro (S1) series has a RS-485 communications port (RJ-45) as standard

RS-485 communications are available as standard specification.

Frequency setting potentiometer is standard equipment for Fuji Electric vfd FVR-Micro (S1) series.

Simple manual adjustment of the frequency.

All types of data can be displayed on the keypad.

The setting frequency, output frequency, load speed, output current, output voltage, alarm history and input power, etc., can be displayed.

Fuji Electric frequency inverter FVR-Micro (S1) series has a one-touch operation for removal of the control circuit terminal block cover.

The alarm history for the 6 latest alarms is recorded

Alarm history from back as far as the 6 latest alarms can be checked.

All Fuji Electric drive FVR-Micro (S1) series models are equipped with an inrush current suppression circuit.

An inrush current suppression circuit is provided as standard in all models, so the cost of peripheral devices such as input magnetic contactors can be reduced.

Sink/source can be switched

The input/output mode (Sink/Source) of the digital input terminals can be switched by means of an internal switch.
