After enetring the motor data in the quick set up menu as told above , now we only need to auto tune the drive and the drive will automatically calculate the motor information on its own.This is a very unique feature which is available in the Baldor VFD. Inside the quick set up menu there is one option of "One step tuning" , slect this and press enter to start the auto tuning of the drive. The test will start and a series of 4 - 5 test will be done , like feedback test, current and speed loop test. Just press enter after each test is completed.

Afte all the test are passed , come to the main menu and select the Local mode , to test the motor. Now press the FWD button on the keypad and the motor will start rotating , if you want to increase the RPM then press the up arrow key on the keypad. If all the test in the auto tune are passed the motor will rotate very smoothly. Now there is nothing to do in drive. All other functions like accel/decel time you can set very easily later on. One Step tuning is a very good method to quickly set up the drive.
