(PMSMs)
What this chapter contains
This chapter gives basic guidelines on how the ACS355 drive parameters should be
set when using permanent magnet synchronous motors (PMSMs). In addition, some
hints are given for tuning the motor control performance.
Setting the parameters
With PMSMs special attention must be paid on setting the motor nominal values
correctly in parameter group 99 START-UP DATA. It is always recommended to use
vector control. If the nominal back-emf of the motor is not available, a full ID run
should be performed for improving performance.
