Saturation characteristic speed to determine / Sat_char n determ

Access level: 3
Can be changed: T, U
Unit group: -
Min:
26 [%]
Description: Sets the speed to determine the saturation characteristic.
The percentage value is referred to p0310 (rated motor frequency).
Dependency: See also: p0310, p1959
See also: F07983
Note
The saturation characteristics should be determined at an operating point with the lowest possible load.

(PM330)

Description: Sets the speed to determine the saturation characteristic.
The percentage value is referred to p0310 (rated motor frequency).

p1965

Speed_ctrl_opt speed / n_opt speed

Access level: 3
Can be changed: T, U
Unit group: -
Min:
10 [%]
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: See also: p0310, p1959
See also: 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.
