Saturation characteristic rotor flux / Sat_char rot flux

VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Motor identification
Not for motor type: PEM, REL
Min
- [%]
Description: Displays the rotor flux values of the identified saturation characteristic.
After they have been determined, the values are transferred to p0362 ... p0365.
Index: [0] = Value 1
[1] = Value 2
[2] = Value 3
[3] = Value 4
[4] = Value 5
p1965

Speed_ctrl_opt speed / n_opt speed

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Motor identification
Not for motor type: REL
Min
10 [%]
Description: Sets the speed for the identification of the moment of inertia and the vibration test.
Induction motor:
The percentage value is referred to p0310 (rated motor frequency).
Synchronous motor:
The percentage value is referred to the minimum from p0310 (rated motor frequency) and p1082 (maximum speed).
Dependency: Refer to: p0310, p1959
Note: In order to calculate the inertia, sudden speed changes are carried out - the specified value corresponds to the lower
speed setpoint. This value is increased by 20 % for the upper speed value.
The q leakage inductance (refer to p1959.5) is determined at zero speed and at 50 % of p1965 - however, with a
maximum output frequency of 15 Hz and at a minimum of 10% of the rated motor speed.
p1967

Speed_ctrl_opt dynamic factor / n_opt dyn_factor

VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Motor identification
Not for motor type: REL
Min
1 [%]
Description: Sets the dynamic response factor for speed controller optimization.
After optimization, the dynamic response achieved is displayed in r1968.
Dependency: Refer to: p1959, r1968
Note: For a rotating measurement, this parameter can be used to optimize the speed controller.
p1967 = 100 % --> speed controller optimization according to a symmetric optimum.
p1967 > 100 % --> optimization with a higher dynamic response (Kp higher, Tn lower).
If the actual dynamic response (see r1968) is significantly reduced with respect to the required dynamic response
(p1967), then this can be as a result of mechanical load oscillations. If, in spite of this load behavior, a higher dynamic
response is required, then the oscillation test (p1959.4 = 0) should be deactivated and the measurement repeated.
