In order to achieve a satisfactory controller response, as a minimum, you must match the
subfunctions having a gray background as shown in the diagram above with your particular
application.
● Motor and current model: In the basic commissioning, correctly set the motor data from
the rating plate corresponding to the connection type (Y/Δ), and carry out a motor data
identification routine at standstill.
● Speed limits and torque limits: In the basic commissioning, set the maximum speed
(p1082) and current limit (p0640) to match your particular application. When completing
the basic commissioning, the inverter calculates the torque and power limits
corresponding to the current limit. The actual torque limits are obtained from the
converted current and power limits and the set torque limits.
● Speed controller: Start the rotating measurement of the motor data identification. You
must manually optimize the controller if the rotating measurement is not possible.

Select motor control

Vector control is already preset
To achieve a good controller response, you must adapt the elements marked in gray in the
figure in the overview diagram above. If you selected vector control as control mode in the
basic commissioning, you will have already set the following:
● The maximum speed for your application.
● The motor and current model: If the motor data in the inverter correspond to the motor
data on the rating plate, then the motor and current model in the inverter are correct and
the vector control can operate satisfactorily.
● The inverter calculates the torque limits matching the current limit that you have set for
the basic commissioning.
Regardless of it, you can also set additional positive and negative torque limits or limit the
power of the motor.
● The inverter has a preset speed controller with self-optimization (rotating measurement).
If you want to continue to optimize this setting, follow the instructions further down in this
chapter.
