Total control & automation offers small-size vector inverter, n100 series. Features: advanced sensor less vector control function - realize smooth driving without motor vibration and high precise driving with no effect of changing load; show high torque of 200 per cent or greater at speeds and operation; strengthening auto-tuning function - automatically measure motor parameters; realize optimal motor control without torque dropping and speed fluctuation, etc; strengthening the pid control function - strengthening the speed control program for controlling flux, temperature, pressure and so forth; apply to high precision systems by high-speed responsibility; realize tripless driving by adding current suppression - realise stable driving at instant impact load and overload by adding over-current level adjusting function; maintains constant speed on changing load suddenly by rapidity speed restoration characteristics; etc; mmi function using rs485 communication [hims 2000] - built-in rs485 communication standard using modbus protocol possible flexible application for various fa system, on remote driving at upper system and easy monitoring the status of driving; realise remote motor control drive using exclusive mmi program; and sink/source type signal selectable - many types of programmable controllers are easily connected.
