Features of Hitachi inverter series: The latest development technology of high starting torque, intelligent speed sensorless vector control, can achieve optimal high torque without motor parameter tuning. Gate suppression function: advanced acceleration overcurrent trip suppression function and deceleration overvoltage trip suppression function. Trip suppression enables continuous and stable operation of the drive system. Removable control terminals Plug-in type control terminals facilitate wiring and minimize work time. The input logic sink/source type can be switched to flexibly adapt to peripheral devices (etc.). The disassembled digital operator enables remote operation via cable connection. Even if the operator is removed, the working status of the inverter can be observed from the three buttons on the body (power, alarm, operation). The strong control inverse function can change the polarity of the deviation between the set value and the feedback value. The upper and lower limits of the set value can limit the output frequency of the inverter. If you want to set the calculation function to the terminal, you can add/subtract an offset frequency to the output frequency.
