7.3 Parameters
p1967
Speed_ctrl_opt dynamic factor / n_opt dyn_factor
Access level: 3
Can be changed: T, U
Unit group: -
Min:
1 [%]
Description:
Sets the dynamic response factor for speed controller optimization.
After optimization, the dynamic response achieved is displayed in r1968.
Dependency:
See also: p1959, r1968
See also: 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.
r1968
Speed_ctrl_opt dynamic factor actual / n_opt dyn_fact act
Access level: 3
Can be changed: -
Unit group: -
Min:
- [%]
Description:
Displays the dynamic factor which is actually achieved for the vibration test
Dependency:
See also: p1959, p1967
See also: F07985
Note
This dynamic factor only refers to the control mode of the speed controller set in p1960.
