Functional Description
CG Drives & Automation, 01-5326-01r3b
Flux Optimization [354]
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. 93 shows the area within which
the Flux Optimization is active.

Maximum power [355]
Sets maximum power. Can be used for limiting motor
power in field weakening operation. This function operates
as an upper power limit and internally limits the parameter
“Max Torque [351]” according to :
Tlimit = Plimit[%] / (Actual Speed / Sync Speed)
Communication information
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

is set correctly.
