Inverter The inverter adopts the sixth generation sensorless vector control technology. According to Hitachi, the smart sensorless vector control of the new inverter no longer requires a complex automatic tuning process to achieve optimal control performance. At the same time, it comprehensively adopts Hitachi's latest inverter system power module. The new frequency converter is versatile, compact and highly functional. Hitachi inverters cover a range of the latest and enhanced features with unparalleled simplicity and applicability. These functional groups include advanced anti-trip functions, side-by-side installation functions, built-in timing logic, automatic function and DIP switch manual setting functions, removable control terminal connectors and R remote communication interfaces . In addition, the frequency converter is available with an option to provide flexible and low-cost keypad installation. Hitachi once again leads the product development of frequency conversion technology and promotes the setting of a new standard for small transmission products. Product features: High-performance vector frequency conversion
