CatalogAbout Simple and compact inverter VF-nC3
Developed on the concepts of "easier operation," "easier installation" and "easier settings," this inverter can be used for living-related equipment such as food processing machines, transport machines, fans and pumps.
Input voltage class/applicable motor capacity
・ Single-phase 120 V input: 0.1 to 0.75 kW
・ Single-phase 240 V input: 0.1 to 2.2 kW
・ Three-phase 240 V input: 0.1 to 3.7 kW
Features
Easy operation
・The large setting dial in the center of the panel allows easy operation.
・To set a parameter, turn the setting dial and push its middle part to select the setting.
・The setting dial can also be used as a frequency setting knob.
Easy installation
・Like the power distributor, this inverter has a vertically oriented main circuit terminal block, which makes wiring arrangement easy and keeps the wiring space in order.
・Multiple units can be installed side by side, saving the space inside the control panel.
・The main circuit terminal block cover can be removed with a wiring screwdriver as well. This ensures easy wiring work and safety.
Easy settings
・Only the frequently used parameters are shown (easy mode).
Using the EASY key, you can toggle between two modes.
[Easy mode]: Only the eight most frequently used parameters are shown. Up to 24 parameters can be registered.
[Standard mode]: All the parameters can be shown.
Adopts
- Built in the equipment, saving the space inside the control panel.
- The input of single-phase 100 V and single-phase 200 V is supported.
- Safety function
- Eco-friendly design
Built in the equipment, saving the space inside the control panel.
Like the power distributor, this inverter has a vertically oriented main circuit terminal block, which makes wiring arrangement easy and keeps the wiring space in order.
Also, multiple units can be installed side by side, saving the space inside the control panel.
The input of single-phase 100 V and single-phase 200 V is supported.
A power supply of single-phase 100 V or single-phase 200 V can be used.
・Single-phase 100 V input: 0.1 to 0.75 kW
・Single-phase 200 V input: 0.1 to 2.2 kW
* The applicable motor is a three-phase 200 V motor. Variable-speed operation can be performed by replacing the single-phase motor with a three-phase motor.
Safety function
You can set the function to prohibit parameters from being changed. Protection with a four-digit password is available for enhanced security.
The inverter also features a function that stores all customer-defined settings at once and resets changed values to those settings.
Eco-friendly design
The inverter is compliant with the RoHS Directive (Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical Equipment).
Also, the single-phase 200 V models have a built-in EMC noise filter as a standard feature. The filter significantly reduces the harmonic noise generated by the inverter, achieving compliance with the EU EMC Directive.
Performance
Superb motor control
Select the motor control mode that matches the load characteristic of the equipment to bring out the best equipment performance.
・To change the rotation speed
Operate the inverter in the default "V/f constant mode."
・When the equipment requires high torque
Use sensor-less vector control, which enables stable high-torque operation from the start until the rated rotation speed is reached.
Auto energy-saving mode
The inverter supports the auto energy-saving mode for operating fans, pumps and other devices in an energy-saving manner. Also, a current appropriate for the load flows. (The motor constant needs to be set.)
A wide range of application conditions
The inverter supports comprehensive specifications, allowing it to be applied to a wide variety of equipment around the world.
