Note: If the ground fault test was selected, but not successfully performed, then sufficient current will not be able to be
established during the test pulses.
Re bit 04:
A test pulse longer than one sampling time has occurred
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.
