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.
Re 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.
Re bit 21 = 1:
The converter output voltage measurement is calibrated at the start of the motor data identification.
Description: Sets the motor data identification routine.
The motor data identification routine is carried out after the next power-on command.
p1910 = 1:
All motor data and the drive converter characteristics are identified and then transferred to the following parameters:
p0350, p0354, p0356, p0357, p0358, p0360, p1825, p1828, p1829, p1830
After this, the control parameter p0340 = 3 is automatically calculated.
