  • Page 95 Trial Operation Precautions Before Using Autotuning Read the following precautions before using autotuning. Autotuning an Inverter is fundamentally different from autotuning a servo system. Inverter autotuning • automatically adjusts parameters according to detected motor data, whereas servo system autotuning adjusts parameters according to the detected size of the load. When speed precision or torque precision is required at high speeds (i.e., 90% of the rated speed or higher), •...
