The auto-tune function features 3 types of motor tuning that are available on Yaskawa E7, F7,
G7 and P7 drives. They are:
1. Line to line resistance:
This tuning calculates the motor terminal resistance value. The motor does not turn
during this function.
2. Auto-tuning without motor rotation:
This tuning function calculates most of the motor parameters without turning the motor
shaft. It is available only on F7 and G7 in the Open Loop Vector and Closed Loop
Vector control modes.
3. Auto-tuning with motor rotation:
This tuning function calculates all of the motor parameters with turning the motor shaft.
It is available only on F7 and G7 in the Open Loop Vector and Closed Loop Vector
control modes. The motor mechanical load must be disconnected to allow the tuning
function to operate correctly.
