Bit field: Bit Signal name
00 Enc test active
01 Saturation characteristic identification
02 Moment of inertia identification
03 Recalculates the speed controller parame-
ters
04 Speed controller vibration test
Dependency: Refer to: A07988
Note: The encoder is only tested if the speed controller optimization with encoder is selected (p1960 = 2).
The following parameters are influenced for the individual optimization steps:
Bit 00: None
Bit 01: p0320, p0360, p0362 ... p0369
Bit 02: p0341, p0342
Bit 03: p1400.0, p1458, p1459, p1460, p1462, p1462, p1463, p1470, p1472, p1496
Bit 04: Dependent on p1960
p1960 = 1: p1400.0, p1458, p1459, p1470, p1472, p1496
p1960 = 2: p1458, p1459, p1460, p1461, p1462, p1463, p1496
p1960 Speed controller optimization selection / n_opt selection
VECTOR Can be changed: T
Data type: Integer16

Description: Sets the speed controller optimization.
After the next power-on command, the speed/velocity controller is automatically optimized.
The setting possibilities of the parameter depend on the open-loop/closed-loop control mode (p1300):
p1300 < 20 (V/f control): It is not possible to select the speed controller optimization routine.
p1300 = 20, 22 (sensorless operation): Only speed controller optimization can be selected in the sensorless mode.
p1300 = 21, 23 (operation with encoder): Both versions (sensorless and with encoder) of the speed controller opti-
mization routine can be selected.
Values: 0:
1:
2:
Dependency: Refer to: p1300, p1900, p1959
Refer to: A07987
Notice: In order to permanently accept the determined settings they must be saved in a non-volatile fashion (p0971,
p0977).
Note: When the speed controller optimization is activated, it is not possible to save the parameters (p0971, p0977).
p1961 Saturation characteristic speed to determine / Sat_char n determ
VECTOR (n/M) Can be changed: U, T
Data type: Floating Point
P-Group: Motor identification
Min
26 [%]
Description: Sets the speed to determine the saturation characteristic and the encoder test.
The percentage value is referred to p0310 (rated motor frequency).
Dependency: Refer to: p0310, p1959
Refer to: A07983
Note: The saturation characteristics should be determined at an operating point with the lowest possible load.
