Mitsubishi's FRA560L900KNA inverter is classified as a high-capacity model engineered for demanding applications. The device demonstrates impressive frequency accuracy, achieving ±0.2% in analog mode and ±0.01% in digital mode. Users can adjust the base frequency from 0 to 400Hz, supporting various torque modes. The starting torque is notable at 150% at a frequency of 0.5Hz, leveraging advanced magnetic flux vector control for optimal motor performance.
The inverter allows users to manually adjust the torque boost as needed, while the acceleration and deceleration times can be configured from 0 to 3600 seconds. For braking applications, it features a DC dynamic brake with adjustable settings for frequency (ranging from 0 to 120Hz), time (from 0 to 10 seconds), and voltage levels (from 0 to 30%).
The inverter ensures compatibility with various motor systems with a broad output frequency range from 0.2 to 400Hz. It operates within an input voltage range of 575V AC (3-phase), with a tolerance between 488 and 632V, making it adaptable to different electrical environments. The rated current under constant torque is recorded at 1210A, and it can handle overload conditions, maintaining 150% capacity for up to 60 seconds and 200% for 0.5 seconds, depending on torque specifications.
Cooling is provided through forced air, maintaining efficiency during operation. Ambient temperature conditions range from -10°C to 50°C for constant torque applications and up to 40°C for variable torque operations. The inverter's protective structure is of an open type classified as IP00 or IP20, making it appropriate for controlled environments. With a power capacity of 1205 kVA, the FRA560L900KNA is a powerful choice for managing complex systems requiring reliable and effective motor control.
