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.
For 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.
For 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 switch-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.
p1910 = 20:
Only for internal SIEMENS use.
Value: 0: Inhibited
1: Complete identification (ID) and acceptance of motor data
2: Complete identification (ID) of motor data without acceptance
20: Voltage vector input
21: Voltage vector input without filter
22: Rectangular voltage vector input without filter
23: Triangular voltage vector input without filter
24: Rectangular voltage vector input with filter
25: Triangular voltage vector input with filter
26: Enter voltage vector with DTC correction
27: Enter voltage vector with AVC
28: Enter voltage vector with DTC + AVC correction
Dependency: "Quick commissioning" must be carried out (p0010 = 1, p3900 > 0) before executing the motor data identification
routine!
When selecting the motor data identification routine, the drive data set changeover is suppressed.

NOTICE
After the motor data identification (p1910 > 0) has been selected, alarm A07991 is output and a motor data
identification routine is carried out as follows at the next switch-on command:
- current flows through the motor and a voltage is present at the drive converter output terminals.
- during the identification routine, the motor shaft can rotate through a maximum of half a revolution.
- however, no torque torque is generated.
