Auto tuning of V&T EcoDriveCN® frequency inverters (AC drives)

• First step, must disconnect from the load. If the motor can be disconnect from the load, it can select rotation auto-tuning (P9.15=2), or select static auto-tuning only


• If the frequency inverter (AC drive) power does not match the motor power, select static auto-tuning.
  After the tuning, manually change the no load current P9.05 to about 40% of the motor rated current P9.04


• Setting P0.01=5, set parameters to the default setting in the factory


• Setting basic frequency of the motor P0.15, according to motor nameplate


• Setting rated voltage of the motor P0.12, according to motor nameplate


• Setting pole of the motor P9.01, according to motor nameplate


• Setting rated rotation of the motor P9.02, according to motor nameplate


• Setting rated power of the motor P9.03, according to motor nameplate


• Setting rated current of the motor P9.04, according to motor nameplate


• Setting P9.15=1, and pressure RUN key to perform static auto-tuning


• Setting P9.15=2, and pressure RUN key to perform static rotating-tuning.
  If perform rotating-tuning, should be careful because the motor will be run after pressure RUN key.


• After auto-tuning, the motor will stop automatically.

According to the process of auto tuning, the nameplate of motor plays an important role. So it's important to set the parameters as the nameplate.
