p1967 Speed_ctrl_opt dynamic factor / n_opt dyn_factor
Access level: 3 Calculated: CALC_MOD_ALL Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: -
Unit group: - Unit selection: - Function diagram: -
Min:
1 [%]
Max:
400 [%]
Factory setting:
100 [%]
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.
