Parameters
7.2 Parameter list
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.

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.

See also: F07990, A07991
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.
Note
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.
3. For settings 27 and 28, the AVC configuration set using p1840 is active.
The switch-on command must remain set during a measurement and after the measurement has been completed, the
drive automatically resets it. The duration of the measurements can lie between 0.3 s and several minutes. This time
is mainly influenced by the motor size. At the end of the motor data identification, p1910 is automatically set to 0, if only
the stationary measurement is selected, then p1900 is also reset to 0, otherwise, the rotating measurement is activated.
