7B.5 Ride Quality Adjustments - O. Thompson Microflite Ultra 2000 Installation & Adjustment Manual

Microflite Ultra 2000 - Magnetek HPV 900 AC Vector Drive
Verify that the FLUX REFERENCE (found under Display Menu – Power Data D2) is
5.
100%. If not, reduce the car speed until it is.
With the car running from top to bottom and back, observe EST NO LOAD CURR
6.
(found under Display Menu – Power Data D2). Enter this estimated value into the
parameter % NO LOAD CURR.
7. Repeat steps 5 and 6 until the value of the EST NO LOAD CURR and the % NO LOAD
CURR are equal.
8. Verify that the motor torque is still ± 15% and flux reference is still 100%. If not, adjust
accordingly and adjust the %NO LOAD CURR as needed.
9. Increase the car speed to 100% of contract speed. To do this, re-adjust MPU pot R25
so 7.00 volts is present at relay board terminals RJ20-7 (positive) to RJ20-7 (negative)
when contract speed is demanded.
With balanced load still in the car, run the car from top to bottom and back. While the
10.
car is running, observe EST NO LOAD CURR (found under Display Menu – Power
Data D2). Compare this value to the value found under %NO LOAD CURR (found
under Adjust Menu – Motor M5).
If the EST NO LOAD CURR value is 2% larger than the %NO LOAD CURR then
11.
increase FLUX SAT SLOPE 2 by 10%. If the EST NO LOAD CURR and %NO LOAD
CURR values are within 2%, continue to step 12.
12. Repeat steps 10 and 11 until EST NO LOAD CURR and %NO LOAD CURR are within
2%.
13. Place full load in the car. Run the car at contract speed from top to bottom and back.
Observe EST RATED RPM (found under Display Menu – Power Data D2).
14.
Enter this value into RATED MTR SPEED (found under Adjust Menu – Motor M5).
15.
16. Remove full load from the car and place balanced load in it. Run the car from bottom to
top and back.
17. Observe EST INERTIA (found under Display Menu – Elevator Data D1). Write down the
value for up and down.
Average the up and down values of EST INERTIA. Enter this value into INERTIA (found
18.
under Adjust Menu – Drive A1).

1. If an Adaptive Tune was not required, it is now necessary to determine the system's
inertia. Access the EST INERTIA parameter in the drive (found under Display Menu –
Elevator Data D1). If the Adaptive Tune was performed, go to step 4.
With balanced load still in the car, make a high speed run up and down. Average the
2.
up and down values of EST INERTIA.
Enter the value calculated in the previous step into INERTIA (found under Adjust Menu
