com Loaded with new technology! Adaptive flux observer The motor flux is continuously updated using the motor current and the inverter output voltage.
Motor temperature - torque characteristics 120 110 Reduces torque fluctuation caused by changes in the motor temperature by using online tuning with the adaptive flux observer, high torque accuracy is realized regardless of changes in the motor temperature (Vector control with encoder).
Torque (%) The motor flux is calculated at high precision, improving torque accuracy.
Without online tuning 100 90 80 70 With online tuning Motor 22kW 60 30 50 70 90 110 Motor temperature (°C) Improved torque accuracy makes, this product suitable for torque controlled applications such as winding machines, printing machines (tension control) and steel lines (helper control using speed-torque).
CONTENTS Model Configuration Explanation of operation panel Explanation of parameter unit Inverter setup software List of parameters Explanation of parameters 4 14 15 15 16 19 Connection example 20 Protective Functions 22, 23 Selection of peripheral devices and options 23 List of options 25 Explanation of standalone options 26 Precautions for use and selection 31 Simple gain tuning Rotation speed (r/min) The motor's load inertia is estimated online, and the speed control gain and position loop gain are adjusted automatically.
Comparison of speed accuracy before and after tuning 1200 1000 800 600 400 0 After tuning 1 Before tuning Speed control gain and position loop gain adjustments are no longer necessary! The motor's load inertia estimated automatically online from the output torque during acceleration/deceleration provides the optimum speed control gain and position loop gai...
