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 bit 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.
Dependency: Refer to: p1959
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).
Description: Displays the dynamic factor which is actually achieved for the vibration test
Dependency: Refer to: p1959, p1967
Refer to: F07985
Note: This dynamics factor only refers to the control mode of the speed controller set in p1960.
Description: Displays the identified moment of inertia.
Dependency: Refer to: p0341, p0342, p1498, p1959, p1960
