FLUX / Magnetizing configuration
The function is active only in a Sensorless and Field oriented mode and is useful for
undesired motor shaft rotation.
It allows to lock the flux position, Lock flux, and to set a Ramp time of the magnetizing
current
H01.00 - Magn ramp time
.
In the configurations it is possible to start the Lock flux function. Via the
H01.01 - Lock
flux pos
parameter, it is possible to lock the flux position when the following selected
condition is satisfied:
· Off non-active function
· At magnetization during magnetization
· At Spd=0 with Speed 0 delay signal
· At magn & Spd=0 during magnetization and with a Speed 0 delay signal
· At magn and Ref=0 during magnetization and Ref 0
· At Ref=0 with Reference 0

In order to have a better performances of Autocapture (Catch on Fly) function, it is
recommended to set
H01.01 - Lock flux pos
= At Ref = 0.
Furthermore, in
H01.00 - Magn ramp time
it is possible to set the magnetizing current
ramp time in seconds, which can be used:
• To slow down the temporary magnetizing period and avoid a rotation of the motor
shaft due to the stator-rotor alignment
• To speed up the magnetizing phase

For Autocapture function in Sensorless reg. mode, enabling of Autocapture (Catch
on Fly) function if required and
H01.01 - Lock flux pos
parameter must be set at
“Ref = 0”
