Mitsubishi's FR-A720-00030-N6 belongs to the FREQROL FR-A7 series of frequency inverters. This unit utilizes heatsink cooling to maintain optimal temperature during operation. It employs both soft-PWM and high carrier frequency PWM control methods to control output, enhancing its adaptability for various tasks. The inverter has a maximum output frequency of 400 Hz and a minimum of 0.2 Hz, allowing precise modulation based on specific requirements.

The input voltage range is between 200 and 240 volts AC for three-phase systems. The inverter supports a Modbus RTU communication protocol, facilitating straightforward integration into existing systems. Designed with an IP20 protection rating, it is suitable for environments where dust and moisture are limited.

Through its overload current capabilities, users can benefit from abnormal conditions, permitting up to 150% for 60 seconds and 200% for 3 seconds in normal duty cycles. The multi-speed operation ensures continuity, preserving original performance during instantaneous power interruptions. The input for external thermal relay selection supports polarity reversible operation, adding versatility to its functionality.

The system features a secondary brake sequence and stop-on-contact control specifications for operational control, adapting to high-speed load torque frequency control. This inverter functions within the standard network frequencies of 50 and 60 Hz, making it suitable for diverse applications requiring reliable speed regulation.
