5.7.2.2 Commissioning vector control
Vector control with and without speed encoder requires careful commissioning and therefore
must only be performed by commissioning engineers that are experienced in handling this
type of control.
Steps when commissioning the vector control
1. Carry out quick commissioning (P0010 = 1)
In order to ensure that the vector control functions perfectly, it is absolutely imperative
that the motor data is entered correctly
2. Run the motor data identification (P1900 = 2)
The motor data identification must be carried out with the motor in the cold state. The
motor data identification must be carried out after the quick commissioning as the quick
commissioning supplies output data for the motor model and the motor data identification
makes these even more precise
3. Carry out the automatic speed controller optimization (P1960 = 1)
