The 3G3FV-PFI-4120E from Omron is a general-purpose inverter characterized by its adaptable control modes. Users can select from V/f, V/f with PG, sensorless flux vector, and full flux vector control to best suit their application’s needs. It offers robust torque performance, achieving up to 150% torque from a standstill in closed-loop mode and maintaining 100% torque at 1 Hz in open-loop configurations.

This inverter features impressive speed control accuracy, specified at 0.2% without feedback and 0.02% with encoder feedback (PG). Additionally, the built-in auto-tuning function simplifies setup further.

The device comes equipped with a user-friendly digital operator that utilizes a two-line LCD displaying 16 characters per line, available in seven different languages, enhancing usability across diverse contexts. For communication, the unit has a built-in RS-232C port that supports open protocol configurations.

Moreover, the 3G3FV-PFI-4120E incorporates PID control and droop control functionalities, allowing for fine-tuning of process variables and load sharing, respectively. A torque limit function protects the system by restricting the maximum torque output.

It also features a position lock (zero-servo) for precise positioning demands. The inverter ensures high starting torque achievable from 1/100 of the low speed without encoder feedback and can reach torque ratings of 150% or more at zero frequency with encoder feedback. This inverter is designed for seamless operation, incorporating true flux vector control, which permits DC-like performance even when utilizing standard AC motors.
