2.2 List of parameters
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 de-activated 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.
Description: Displays the determined moment of inertia of the drive.
After it has been determined, the value is transferred to p0341, p0342.
Dependency: IEC drives (p0100 = 0): unit kg m^2
NEMA drives (p0100 = 1): unit lb ft^2
Refer to: p0341, p0342, p1959
Refer to: F07984
Description: Displays the vibration frequencies determined by the vibration test.
Index: [0] = Frequency low
[1] = Frequency high
Dependency: Refer to: p1959
Refer to: F07985
