The n-and-push" setting dial makes setup easily
The large setting dial at the center of the front panel allows you to set the parameters easily. Just turn the setting dial until you get the right parameter and push the setting dial to select.
You can also use the setting dial to set the reference frequency.

The RUN and STOP keys allow to operate easily.
You can operate the inverter with RUN and STOP keys on the front panel. The front cover may be closed to conceal the other keys to avoid accidental key pressing.


Easy to set parameters
1. Showing most frequency used parameters in easy mode.
The EASY key allows you switch between Easy mode and Standard mode.
Easy mode: Scrolls through a list of only eight parameters. You can optionally add up to 24 parameters to the list.
Standard mode: Rotates through all parameters.

2. Guides you step by step through parameters you need to set up
Since the guidance feature shows one parameter at a time according to the selected function, you can interactively edit its value.
Auto-guidance function is available with motor parameter setup, preset speed selection and analog signal control, etc.

Built-in RS-485 communication
Built-in RS-485 communication enable to control the inverter and build network.
- Communication rate: 38.4 kbps max.
- Compatible with the Modbus RTU and Toshiba protocols.
You can connect a PC to manage parameters and monitor operating conditions.

The vertically oriented main circuit terminal block allows easy wiring.
Like power distribution devices, the main circuit terminal block of the VF-nC3 is vertically oriented to make wiring easy and minimize tangles of cable.

Side-by-side installation for space-saving
Generally, inverters must be places in consideration of radiation of heat. The VF-nC3 can be placed side by side with no gap, saving inside of control panel space. *1

The covers for the main circuit terminal block ensure safety
You can remove the covers for the main circuit terminal block with a screwdriver. Sine the covers can be attached after the wiring of the main circuit terminal block, the VF-nC3 can be installed easily and safety.
