2.5 Preliminary Checks and Calibration
The AC motor and controller were setup by SuperFlow prior to shipping with all the required
parameters programmed in the controller. If the controller or motor has been replaced or repaired,
the programming may have to be performed again. Contact SuperFlow Customer Service for the
necessary information and procedures.
CAUTION:
Operation of the AC Motor and dynamometer can sometimes be very loud. Always
wear proper ear protection.
2.5.1 Motor Rotation Direction
1. Double check all connections ensuring they are correct and that terminal screws are tight.
2. Turn on the AC power source to the motor drive. The display on the motor drive may become
active and the cooling fan may come on but the motor should not start moving.
3. Turn on the motor controller power switch if applicable. ABB controllers typically do not have
a power switch.
4. Turn on the power to the SuperFlow data acquisition sensor box.
NOTE:
The following procedure assumes an ABB ACS800 motor controller. Refer to the
manufacturers operation manual for other makes and models.
5. Select the desired language if prompted on the ABB drive. This procedure assumes English.
6. The next step is to verify the motor is turning in the correct direction.
• Place the controller in “Local” by pressing the Local/Remote button until “L” is displayed
on the status display.
• Make sure the motor and dynamometer roll is clear of any obstruction.
• Press the ACT button to display the status row.
• Press the REF button to access manual control.
• Press the up arrow button to increase the speed reference by a small amount. Press the
green start button. The motor will make a high pitched sound and start turning. Press the
red stop button to stop the motor.
• If the motor turns in the wrong direction interchange the red and white wires to the motor
at the controller connections.
CAUTION:
Wait 5 minutes after switching motor power off before touching any wires.
• Recheck the motor rotation direction.
• Stop the motor and place the controller in “Remote” mode.
