The FRA520 from Mitsubishi falls under their FREQROL FR-A5 series as a sophisticated transistorized inverter. It’s engineered to handle a wide output frequency spectrum from 0.2 to 400 Hz, which is essential for various motor control tasks. Users can customize the base frequency anywhere between 0 and 400 Hz, offering significant flexibility for application needs. The inverter operates using either Soft-PWM or high-frequency PWM control mechanisms, enhancing efficiency.
Frequency resolution is notably precise, at 0.015 Hz for analog inputs while digital inputs achieve a resolution of 0.01 Hz. The accuracy claims are impressive as well: ±0.2% for analog and a tight ±0.01% for digital frequency readings, ensuring operational reliability.
Performance metrics include a starting torque of 150% achievable at just 0.5 Hz, enabling effective motor starts even under heavy load conditions. Both acceleration and deceleration times are adjustable, allowing settings from 0 to 3600 seconds to fine-tune system responses as required. For enhanced control, the inverter also provides DC injection braking capabilities within the 0-120 Hz range, allowing for optimized stopping abilities.
Multiple input signals are supported, including analog inputs (0-10 V, ±10 V, and 4-20 mA) and digital inputs (BCD and binary formats). With the capability to configure up to 15 adjustable speeds, the FRA520 allows for versatile operational setups. Stall prevention is additionally supported, adjustable for current levels from 0% to 200%, assisting in maintaining system integrity during variations in load.
Display options for the FRA520 provide real-time insights into frequency, current, voltage, power consumption, and alarms, contributing to enhanced user control. The unit is safeguarded by several protective features, mitigating risks related to overcurrent, undervoltage, and overheating, thus preserving overall system health.
Specifically engineered for an operational environment ranging from -10°C to 50°C, the device can function effectively in conditions up to 90% relative humidity and at elevations of up to 1000 meters, making it adaptable for numerous industrial settings.
