Functional Description
CG Drives & Automation, 01-5326-01r5
Asynchronous motors
Flux Optimization for asynchronous motors 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 state. Fig. 109 shows the area
within which the Flux Optimization is active.
Permanent magnet synchronous and
synchronous reluctance motors
Flux optimization for permanent magnet synchronous
motors and synchronous reluctance motors adjusts the
V/Hz ratio, to either minimize the current or by predicting a
suitable level based on the torque (and speed). Note that
IxR compensation is needed for synchronous motors to get a
good start, also when flux optimization is activated.

Fig. 109 Flux Optimizing
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)
