The division of the set values is made along the MTPA characteristic (maximum torque
per ampere). This characteristic now is determined by

only and the ld current
is calculated as follows:
The remaining current from the total current set value is the lq current (

4.4.5.2 Commissioning
In order to ensure an optimum in dynamic when operating a IPMSM, the following notes
for setting are mandatory:
– Using a Baumueller motor the data can be loaded from a motor data base. All set-
tings are carried out automatically with ProDrive.
– If no Baumueller motor is used, at first an autotuning (see
Z
Autotuning of Current
controller
–
from page 199) must be executed to set the current controller roughly.
– The notch position must be set next.
– The field current can be limited via parameter limit magnetizing current (
Z
146.12
–
).
This is important in order to prevent the demagnetization of the motor.
