Moreover, when the phasing has to be done near a mechanical end stop, those same parameters allow the
user to move the final stable balance point if it is outside of the admitted stroke of the motor to bring it back
inside.
To avoid any sudden movement, the constant current is not immediately applied to the phases but it is linearly
increased until the maximum value set by the parameter K92 is reached.
The time elapsed since the start of the phasing determines the end of the phasing by constant current. It is
determined by parameter K94 and is expressed in seconds:
