MTPF Table
MTPF table according to the flux.
The table is standardized to the maximum Id current (
corresponds to 100%)
and the nominal flux (
). The available flux is calculated from the maximum avail-
able voltage and the electrical speed. The MTPF table can be calculated automatically
via bit 15 of parameter Control word reluctance (
171.14
Nominal flux
Standardization for MTPF table. The nominal flux can be calculated automatically with the
MTPF table from the nominal voltage and the nominal speed.

State field weakening of IPMSM
State of the field weakening

Total reference current
The total current set value at the IPMSM of the won from the speed controller. This is di-
vided to a lq and ld current and the optimum torque results.
171.17
Maximal torque current from flux
This current is obtained from the breakdown torque controller. This is the maximum
torque current that can be impressed in the motor. From this current and the minimum ld
current the limit of the maximum total current is calculated so that an optimum division in
lq and ld current can be reached. This way the maximum torque current can be reached
taking into consideration all the present limits.

Magnetic flux
Nonlinear magnetic flux depending on the current.
