Closed-loop Start-up
22
Enter this estimated value into the motor
parameter.
•
Continue iterating the above two steps until
the two values are within 2%. If the values
do not converge after two iterations, verify
the information entered in the initial set-up is
correct.
•
After the values converge, again verify the
MOTOR TORQUE < 15% and the FLUX
REFERENCE = 100%.
Tuning Motor’s Flux Saturation Curve
With a balanced car, run the car at 100%
contract speed from top floor to the bottom floor
then back to the top floor.
•
During these top / bottom runs observe under
DISPLAY MENU - POWER DATA D2 the
EST NO LOAD CURR value.
•
Compare the displayed value EST NO LOAD
CURR with the value entered for % NO
LOAD CURR under the ADJUST MENU -
MOTOR A5
If the EST NO LOAD CURR is 2% larger than
the % NO LOAD CURR then, decrease the
FLUX SAT SLOPE 2 by 10%.
•
If the EST NO LOAD CURR is 2%
smaller than the % NO LOAD CURR
then, increase the FLUX SAT SLOPE 2
by 10%.
NOTE: If the EST NO LOAD CURR and % NO
LOAD CURR are within 2% of each other, then
continue on to Tuning the Rated Motor RPM.
Continue iterating FLUX SAT SLOPE 2 in 10%
increments until the EST NO LOAD CURR and
% NO LOAD CURR are within 2% of each other.
NOTE: Remember change only the FLUX SAT
SLOP 2 parameter DO NOT change any other
parameter (these were fixed in the previous
steps).
Tuning Rated Motor RPM
With a full-load car, run the car at 100% contract
speed from top floor to the bottom floor then
back to the top floor.
•
During these top / bottom runs observe
under DISPLAY MENU - POWER DATA D2
the EST RATED RPM value.
Enter this estimated value into the motor
parameter.
Continue iterating the above to steps until the
two values are within 3 RPM.
NOTE: Remember change only the RATED
MTR SPEED parameter DO NOT change any
other parameter (these were fixed in the
previous steps).
