The Mitsubishi FRA560L750KNA high-capacity inverter is built to manage substantial power demands in industrial settings. It employs soft-PWM or high-frequency PWM control methods, allowing users to select between V/F mode or advanced vector control options for optimal performance. This capability ensures that the unit can operate effectively across a wide frequency spectrum, ranging from 0.2 Hz to 400 Hz.
For applications requiring robust performance, the inverter can endure overloads of 150% for up to 60 seconds and 200% for a brief 0.5 seconds in constant torque mode, making it suitable for demanding motor tasks. Regarding initial torque, the inverter delivers a notable 150% at 0.5 Hz when advanced vector control is applied, supporting precise motor control at lower speeds.
Maintaining an effective cooling system is critical for reliability; thus, this inverter features forced ventilation cooling to sustain optimal operational temperatures. It operates effectively within a temperature range of -10°C to 50°C (14°F to 122°F). The open frame design offers IP00 or IP20 enclosure ratings, enhancing usability in controlled environments.
Motor compatibility specifies a capacity of 750 kW for constant torque applications and 800 kW for variable torque applications. The rated operational current stands at 990 A for constant torque and 1100 A for variable torque, ensuring adequate power delivery.
The output voltage is a three-phase 575 V configuration, compatible with input specifications of the same voltage and frequency (50/60 Hz). Precision in frequency stability is achieved with a tolerance of ±0.2% at maximum analog settings and ±0.01% at digital configurations. Users can adjust the base frequency profile from 0 to 400 Hz and switch between constant and variable torque settings according to operational needs.
Furthermore, the FRA560L750KNA allows for independent customization of acceleration and deceleration times, ranging from 0 to 3600 seconds, with linear or S-curve profile options. This flexibility makes the unit a versatile component for dynamic industrial applications.
