2 Parameters
2.2 List of parameters
Description: Sets the configuration for the motor data identification.
Note: The following applies to permanent-magnet synchronous motors:
Without de-selection in bit 11, in the closed-loop control mode, the direct inductance LD and the quadrature
inductance Lq are measured at a low current.
When de-selecting with bit 11 or in the U/f mode, the stator inductance is measured at half the rated motor current.
If the stator is inductance is not measured but is to be estimated, then bit 0 should be set and bit 11 should be de-
selected.
Bit 19 = 1:
All parameters are automatically saved after a successful motor data identification.
If a speed controller optimization run is then selected, the parameters are only saved after this measurement has
been completed.
Bit 22 ... 24: only for reluctance motors
Bit 22 = 1:
Only that measurement is carried out that is required for the flying restart of a reluctance motor. The bit is reset after
a successful measurement
