The Mitsubishi FRA560L600KNA high-capacity inverter is engineered for heavy-duty industrial applications. It is designed to operate on a 3-phase power input of 575 V AC and is compatible with 50/60 Hz power supplies. This inverter can handle significant load requirements. It supports rated currents of 800 A for constant torque applications and peaks at 880 A for variable torque settings.
Its overload ability enhances performance, accommodating 150% of the rated current for up to 60 seconds and 200% for shorter spikes of 0.5 seconds. The output frequency ranges from 0.2 to 400 Hz, enabling versatile control of connected motors while offering a frequency accuracy of ±0.2% in analog mode and an impressive ±0.01% in digital mode. The voltage and frequency characteristics can be adjusted across the 0–400 Hz spectrum, with options for both constant and variable torque modes.
In terms of starting torque, the inverter can provide a substantial 150% at just 0.5 Hz due to its advanced flux vector control capabilities, making it suitable for high-demand applications. A manually adjustable torque boost also helps optimize performance according to specific operational needs.
The acceleration and deceleration times are configurable from 0 to 3600 seconds, with either linear or S-curve adjustment options, allowing flexibility in motor driving profiles. For braking, the DC dynamic brake features can operate across a frequency range of 0 to 120 Hz, with adjustable time settings from 0 to 10 seconds and voltage limited to 0–30%. The inverter employs a forced-air cooling method to maintain operational stability.
This high-capacity inverter is designed to support motors with capacities of up to 600 kW for constant torque and 670 kW for variable torque, catering to various industrial machinery. Operating temperature tolerances are set at -10°C to 40°C for variable torque operations and -10°C to 50°C for constant torque applications, promoting adaptability in varying environments. However, it features an open design with an IP00 rating, necessitating careful placement to avoid exposure to harsh external conditions.
