Flux optimisation

Flux optimisation reduces the total energy consumption and motor noise level when
the drive operates below the nominal load. The total efficiency (motor and the drive)
can be improved by 1% to 10%, depending on the load torque and speed.

Parameter 26.01.

FS method

The Flux stabilization method improves the behaviour of open-loop trolley drives and
long travel drives without speed feedback especially when the drive operates around
the zero speed with high load. The method is active on frequencies below 10% of
nominal frequency and when the torque exceeds 30%.
