Auto-Tuning

When using the software the inverter automatically detects the motor constants and saves them as parameters in its internal memory. The auto-tuning function enables the dynamic torque vector control, automatic energy saving operation and other advanced motor controls for general purpose motors. Manual input of motor parameters is possible.

Advanced Functions

Dynamic Torque Vector Control System
Fuji Electric's original dynamic torque vector control system is known for its top-of-the-line performance, delivering stable torque output even at low speeds. This feature has a wide range of applications; including conveyors and high-inertia loads that demand high starting torque.

Slip Compensation Shortens Setting Time
The slip compensation controller works with voltage tuning for even more accurate speed control at low velocity. This reduces speed control variability and stabilizing creep speed for more accurate stopping in conveyors and similar equipment.

Fastest CPU Processor in its Class
Advanced CPU processes data at twice the speed of previous model. Now 64 MHz.

V/f Control
The FRENIC-Mini series of inverters offer a variety of V/f patterns and torque boosts, which include V/f patterns suitable for variable torque load such as general fans or pumps or for special pump load requiring high starting torque. Under this control the inverter controls a motor with the voltage and frequency according to the V/f pattern specified by function codes. Three point can be set for a non-linear V/f pattern.

Torque Boost
In Auto-Tuning : 
This function automatically optimizes the output voltage to fit the motor with its load. Under light load, auto torque boost decreases the output voltage to prevent the motor from over-excitation. Under heavy load, it increases the output voltage to increase the output torque of the motor.

For Greater Control: Manual Mode: 
In torque boost constant voltage is added to the basic V/f pattern, regardless of the load, to the given output voltage. To secure a sufficient starting torque manually adjust the output voltage to optimally match the motor and its load by using a function code. 

Flexibility of Remote / Local Operation

Switching between Local and Remote operating modes for speed reference and start/stop commands can be chosen using an external digital input or over an RS-485 communication network.

USB Keypad

Optional USB keypad is available along with Enhanced PC Loader Software (FRENIC Loader) connectivity.

Network Capabilities

RS-485 Communications Port Standard
Communications can be controlled through the standard RS-485 communications port using Modbus-RTU or Fuji Electric Inverter protocol.

Small & Compact

Side-by-Side Mounting

More than one FRENIC-Mini (C2) inverter can be mounted side-by-side without any gap inside your system control panel, thereby reducing the amount of space required for installation. (Ambient temperature: 40°C (104°F) or lower).
