2.2 List of parameters
Note:
The saturation characteristics should be determined at an operating point with the lowest possible load.
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
Refer to: F07984, F07985
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.
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
Refer to: F07985
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.
Description:
Displays the dynamic factor which is actually achieved for the vibration test
Dependency:
Refer to: p1959, p1967
Refer to: F07985
Note:
This dynamic factor only refers to the control mode of the speed controller set in p1960.
