p1900 = 2:
Sets p1910 = 1 and p1960 = 0
When the drive enable signals are present, a motor data identification routine is carried out at standstill with the next
switch-on command. Current flows through the motor which means that it can align itself by up to a quarter of a
revolution.
p1900 = 3:
Sets p1960 = 0, 1 depending on p1300
This setting should only be selected if the motor data identification was already carried out at standstill.
When the drive enable signals are present, with the next switch-on command, a rotating motor data identification
routine is carried out - and in addition, speed controller optimization by taking measurements at different motor
speeds.
p1900 = 11, 12:
The same as p1900 = 1, 2 with the difference, that after the measurement, the system immediately goes into
operation. For this purpose, p1909.18 is set = p1959.13 is set = 1 .
Value:
0:

1:
Identifying motor data and optimizing the speed controller
2:
Identifying motor data (at standstill)
3:
Optimizing the speed controller (in rotating operation)
11:
Motor data ident. and speed controller opt., switch to operation
12:
Motor data identification (at standstill), switch to operation
Dependency:
Refer to: p1300, p1910, p1960
Refer to: A07980, A07981, F07983, F07984, F07985, F07986, F07988, F07990, A07991
Notice:
p1900 = 3:
This setting should only be selected if the motor data identification was already carried out at standstill.
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).
During the rotating measurement it is not possible to save the parameter (p0971).
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 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, 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.
If a reluctance motor has been parameterized, a pole position identification is carried out during the stationary
measurement. As a consequence, faults that occur can also be assigned to the pole position identification.
For U/f control (p1300), identification with speed controller optimization does not make sense (e.g. P1900 = 1).
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:
Sets p1910 = 1 and p1960 = 0, 1 depending on p1300
When the drive enable signals are present, a motor data identification routine is carried out at standstill with the next
switch-on command. Current flows through the motor which means that it can align itself by up to a quarter of a
revolution. With the following switch-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.
