This document is a guideline for optimizing motor/inverter performance in vector mode through
parameter adjustments. Please note that actual performance of the motor depends on a combination
of many parameters, and is difficult to describe concisely. Trial & error is the customary means to
achieve good motor performance. Therefore please regard this information as just a guide only.
This document only shows technical issues related to vector control. Please refer to the SJ300
Inverter and SJ-FB manuals for detailed information for installation and operation.
