FRA540LG220KNA

Mitsubishi's FRA540LG220KNA inverter is engineered for applications demanding robust performance in a 400V class framework. This unit can operate under a control system that can employ either Soft-PWM or high-frequency PWM techniques to meet diverse requirements. The output frequency can span from 0.2 Hz up to 400 Hz.

A distinctive feature is its multi-speed selection, allowing operation across 15 distinct speed settings. The frequency resolution is finely tuned, enabling adjustments down to 0.015 Hz in analog mode and 0.01 Hz in digital mode. In terms of precision, the unit maintains frequency accuracy within ±0.2% for analog and ±0.01% for digital outputs, ensuring effective motor management.

The inverter's functionality encompasses a torque characteristic enabling operations at constant or variable torque dimensions within the 0 to 400 Hz range. When initiated, it provides a remarkable starting torque of 150% at just 0.5 Hz, making it apt for high-torque applications. To accommodate gradual changes in speed, the acceleration and deceleration times can be configured between 0 and 3600 seconds using linear or S-pattern profiles.

Additional features include a manual torque boost option and DC injection braking capabilities, effective between 0 and 120 Hz. Operation times are configurable from 0 to 10 seconds, and the braking force is adjustable up to 30%. It is designed to function in ambient temperatures ranging from -10°C to +50°C and is built to endure various environmental conditions.

Safety ratings include protection against overcurrent, undervoltage, and stall conditions. The inverter features resettable alarms, allowing for easy troubleshooting. This model exemplifies reliability and adaptability in various industrial applications.
