Process and Application Parameters [300]
Section 11-3
Note
A too high level of IxR Compensation could cause motor saturation. This can
cause a “Power Fault” trip. The effect of IxR Compensation is stronger with
higher power motors.
Note
The motor may be overheated at low speed. Therefore it is important that the
Motor I
2
t Current [232] is set correctly.
Flux Optimization reduces the energy consumption and the motor noise, at
low or no load conditions.
Flux Optimization automatically decreases the V/Hz ratio, depending on the
actual load of the motor when the process is in a steady situation. Fig. 79
shows the area within which the Flux Optimization is active.

Flux Optimizing
Note
Flux optimization works best at stable situations in slow changing processes.
Maximum power [355]
Sets maximum power. Could be used for limiting motor power in field weaken-
ing operation. This function operates as an upper limit and internally limits the
parameter Max Torque [351] according to:
Tlimit = Plimit[%] / (Actual speed / Sync Speed)
