Current increase at motor stop
When the motor controlled with V/F pattern stops, the current increases.
Which parameter should I set to avoid this?

Answer
If the current increases when the motor stops under V/F control (at low speed under a light load), the motor is considered to be in the overexcitation state. Lower the value of Pr.0 (Torque boost) to reduce the current. (Note that reducing the current too much decreases the starting torque.)
In addition, DC injection brake operation during deceleration may increase the current.
In this case, lower the value of Pr.12 (DC injection brake voltage) to reduce the current.
