6B.3.4 Moving Car On Inspection - O. Thompson Microflite Ultra 2000 Installation & Adjustment Manual

Microflite Ultra 2000 -Magnetek HPV 900 AC Vector Drive
The final setting can be calculated by the drive by performing an adaptive tune.
NOTE: This value must be less than 900 RPM on 8 pole motors, 1200 RPM on 6 pole
motors, and 1800 RPM on 4 pole motors or a drive set up fault will occur.
Go to the % NO LOAD CURR parameter. This parameter tells the drive what current is

required to turn the motor at rated speed with no load. This can be determined from the
motor manufacturer's data sheets on new motors. If it is not available, temporarily set
it to 60 % of the full load current on the motor nameplate. The final setting can be
calculated by the drive by performing an adaptive tune on the drive.
6b.3.4 Moving the Car on Inspection
Make sure the controller is on inspection operation. Verify that the hoistway is clear, and the
car is ready to be moved.
1. Using the up/dn toggle on the relay board, attempt to run the car by momentarily
switching it up. The following relays should energize in this order: U, UX, PX, M,
contactor P, & BK.
If the motor moves in the opposite direction, using the programmer, access the
2.
"Configure C0" menu. Go to "User Switches C1" and change parameter "Motor
Rotation" from Forward to Reverse.
3. Run the car again and confirm that the car runs correctly in both directions.
4. Place a digital voltage meter on relay board terminals RJ20-7 (negative) and RJ20-2
(positive). Run the car up on inspection. Adjust pot R17 (Inspection Speed) on the relay
board to obtain +0.7 volts.
5. Using a hand tach, measure the car speed. Using the programmer, access the "Adjust
A0" menu. Access "User Switches A1." Adjust the "Contract Motor Spd" parameter until
the car is running at 10 percent of contract speed.
Adjust the Inspection Speed pot on the relay board to obtain desired inspection speed.
6.
If vibration is observed in the motor, especially during acceleration and deceleration,
decrease the value of the "Response" parameter in "User Switches A1" menu until the
vibration is gone.
Using the programmer, access the "Display D1" menu. Monitor parameter "Speed
7.
Reference." Run the car in the down direction. The speed reference should be
negative.
8. Monitor parameter "Speed Feedback." Run the car in the down direction. The speed
feedback should be negative. If not, reverse the A and A- signals from the encoder to
the drive.
Using the Inspection Speed pot on the relay board, set the inspection speed to 45 - 50
9.
FPM.
Place the car somewhere near the center of the hoistway. On the Limit board, LED D9
10.
should be turned off. It will come on when the car is on Automatic operation with the
doors closed.
