P2.7.2.5 Stop State Flux ID1401

The amount of flux in percentage of the motor nominal flux maintained in the motor after

the drive is stopped. The flux is maintained for the time set by parameter ID1402

Flux Off

Delay

. This parameter can only be used in closed loop motor control.

7.7.2.1

Reduced flux function

Reduced flux function is used to decrease the magnetization current below a certain frequency limit.

This function is used in systems where high starting torque is not needed. This function CAN NOT be

used in any situation where motor nominal torque from zero speed is required.

P2.7.2.6 Reduced Flux frequency

A frequency point where flux starts to reduce to a level defined by

Reduced Flux Level

toward the zero speed.

P2.7.2.7 Reduced Flux level

This parameter defines the flux level when the output frequency is zero. The flux is

reduced linearly from ID1614 to zero frequency.
