p1910 Motor data identification selection / MotID selection
Access level: 3
Can be changed: T

0
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 parame-
ters:
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.
Refer to: p1900
Caution: After the motor data identification (p1910 > 0) has been selected, alarm A07991 is output and a motor data identifi-
cation 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.
Notice: To permanently accept the determined settings they must be saved in a non-volatile fashion (p0971).
Note: 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 influ-
ence on the controller setting.
2. "Without acceptance" means:
The identified parameters are only displayed in the range r1912 ... r1926 (service parameters). The controller set-
tings remain unchanged.
