p1900 = 2:
Induction motors --> set p1910 = 1 and p1960 = 0
Permanent-magnet or separately-excited synchronous motors --> set p1910 = 1, p1990 = 1 and p1960 = 0
When the drive enable signals are present, a motor data identification routine is carried out at standstill with the next
power-on command. Current flows through the motor which means that it can align itself by up to a quarter of a
revolution.
For permanent-magnet or separately-excited synchronous motors, the encoder is adjusted with the next power-on
command. The motor must be free to rotate and rotates through 1.5 revolutions of the motor encoder.

Dependency: In the simulation mode, the parameter cannot be written into.
When selecting the motor data identification routine, the drive data set changeover is suppressed.
Refer to: p1272, p1300, p1910
Notice: 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, p0977).
It is not permissible to activate write protection during the motor identification (p7761).
During the rotating measurement it is not possible to save the parameters (p0971, p0977).
Note: The motor and control parameters of the vector control are only optimally set when both measurements are carried
out (initially at standstill, and then with the motor rotating). The measurement with rotating motor is not performed for
p1300 < 20 (U/f controls).
An appropriate alarm is output when the parameter is set.
The power-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, for example, influenced
by the motor size and the mechanical conditions.
p1900 is automatically set to 0 after the motor data identification routine has been completed.

Description: Sets the motor data identification and speed controller optimization.
The motor identification should first be performed with the motor stationary (p1900 = 1, 2; also refer to p1910). Based
on this, additional motor and control parameters can be determined using the motor data identification with the motor
rotating (p1900 = 1, 3; also refer to p1960); not for p1300 < 20.
p1900 = 0:
Function inhibited.
p1900 = 1:
Induction motors --> set p1910 = 1 and p1960 = 0, 1, 2 depending on p1300
Permanent-magnet or separately-excited synchronous motors --> set p1910 = 1, p1990 = 1 and p1960 = 0, 1, 2
depending on p1300
When the drive enable signals are present, a motor data identification routine is carried out at standstill with the next
power-on command. Current flows through the motor which means that it can align itself by up to a quarter of a
revolution.
For permanent-magnet or separately-excited synchronous motors, the encoder is adjusted with the next power-on
command. The motor must be free to rotate and rotates through 1.5 revolutions of the motor encoder.
With the following power-on command, a rotating motor data identification routine is carried out - and in addition, a
speed controller optimization by making measurements at different motor speeds.
