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.
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.
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.
Refer to: p1900
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 power-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.
Note: If there is a motor holding brake, it must be open (p1215 = 2).
To permanently accept the determined settings they must be saved in a non-volatile fashion (p0971).
When setting p1910, the following should be observed:
1. "With acceptance" means:
The parameters specified in the description are overwritten with the identified values and therefore have an influence
on the controller setting.
2. "Without acceptance" means:
The identified parameters are only displayed in the range r1912 ... r1926 (service parameters). The controller
settings remain unchanged.
