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 two 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).
Estimating System Inertia
The HPV 900 Series 2 software can be used to
calculate the inertia of the entire elevator,
which is used for accurate tuning of the speed
regulator.
The following is a step-by-step procedure for
using the HPV 900 Series 2 to estimate the
elevator system inertia.
Using the Software to Estimate the
System’s Inertia
With a balanced car, run the car at 100%
contract speed from top floor to the bottom
floor then back to the top floor.
Observe the EST INERTIA under DISPLAY
MENU - ELEVATOR DATA D1 for both the
down and up direction.
Average the two values and enter the
DRIVE A1 parameter.
