These parameters provide access to advance elevator drive
parameters related to the motor model, system mechanical model,
and advanced control settings. These values should only be
changed when instructed to do so by the manufacturer.
Sets the corner speed for field weakening. Normally about 80% of
synchronous speed.
Sets the rate of decay of the motor flux in the field weakening range
above the speed adjusted in Ld.18.
The per phase induction motor stator resistance in ohms.
The equivalent induction motor sigma inductance. This value
is calculated from the per phase stator and rotor leakage
inductances.
This is the per phase induction motor rotor resistance.
This is the per phase induction motor magnetizing inductance.
This parameter activates various controllers in the drive. Each
function is binary weighted as listed below. The sum of the these
values determines which are on or off. A value of 8 is the standard
setting before auto-tuning the motor. After auto tuning the value
changes to 41 for induction motors and  for PM motors. To
revert back to operation before auto tuning simple change back
to a valeu of 8.
1 = Motor model control observer active
2 = Rotor resistance temperature adaptation
8 = Maximum output voltage regulation (max 110%)
32 = Active flux control
128 = Flux proofing
