8.1.9 Auto tuning
The motor parameter can be automatically measured. In addition, if the encoder option card is connected to the
main body of the inverter, you can test the operation of the encoder. The motor parameters measured through auto
tuning are used for auto torque boost, sensorless vector control and vector control and so on.

Caution
Be sure to conduct auto tuning after the motor stops operating.
Before conducting auto tuning, make sure that you input the number of motor poles, rated slip, rated
current, rated voltage and efficiency shown on the motor plate. For the items not input, automatically
set values are used.
