p1580[0...n]
Efficiency optimization / Efficiency opt.
CUG120XA_USS
Access level: 3
(PM330)
Can be changed: T, U
Unit group: -
Min:
0 [%]
Description:
Sets the efficiency optimization.
When optimizing the efficiency, the flux setpoint of the closed-loop control is adapted as a function of the load.
For p1580 = 100 %, under no-load operating conditions, the flux setpoint is reduced to 50 % of the rated motor flux.
Dependency:
See also: p0500
Note
It only makes sense to activate this function if the dynamic response requirements of the speed controller are low.
In order to avoid oscillations, if required, the speed controller parameters should be adapted (increase Tn, reduce Kp).
Further, the smoothing time of the flux setpoint filter (p1582) should be increased.
p1581[0...n]
Flux reduction factor / Flux red factor
Access level: 3
Can be changed: T, U
Unit group: -
Min:
0 [%]
Description:
The following applies for a synchronous reluctance motor:
Sets the lower limit of the flux setpoint to evaluate the optimum flux characteristic.
The value is referred to the rated motor flux (p0357 * r0331).
