FR-A540L-280K-EC

The FR-A540L-280K-EC from Mitsubishi's FREQROL FR series serves as a robust solution for variable torque motor control applications. It is capable of functioning in temperatures ranging from -10°C to +50°C, allowing for reliable performance across a diverse range of conditions. This model is meant for indoor usage, specifically in environments free of corrosive or flammable substances, as well as oil mist and excessive dust.

Engineered to operate at altitudes of up to 1000 meters above sea level, this unit can also withstand humid conditions with ambient humidity levels reaching 90% RH or lower (non-condensing). Storage capabilities extend between -20°C and +65°C, providing flexibility during transport and installation.

A forced air cooling system ensures adequate temperature regulation even under extensive loads. The device boasts a frequency setting resolution of 0.01 Hz, giving it precise control over frequency adjustments. Acceleration and deceleration can be finely tuned, with time settings ranging from 0.1 to 3600 seconds.

This controller employs a PWM (Pulse Width Modulation) control system, making it efficient for speed regulation. The enclosure type is classified as open type (IP00), which means it is designed for setup in protected environments. Furthermore, this model tolerates frequency fluctuations of ±5%, increasing its adaptability in various scenarios. The overload characteristics include a capacity of 120% for 60 seconds and 150% for 0.5 seconds, ensuring this controller can handle unexpected load surges effectively.
