Chapter 5 Check Motor Rotation and Direction
This test is to be performed solely from the EQ7 drive keypad. Apply power to the EQ7 drive after all the electrical
connections have been made and protective covers have been re-attached. At this point, DO NOT RUN THE
MOTOR, the keypad should display as shown below in Fig. 5.1 and the speed reference 0.00 should be blinking.
Important: Motor rotation and direction only applies to standard AC motors with a base frequency of 60Hz.
Fig 5.1: Keypad (Stopped) Fig 5.2: Keypad (Running)
Next use the and keys to set a speed reference of 10.00 Hz, then press the key, see Fig 5.2.
The motor should now be operating at low speed running in forward (clockwise) direction.
Next press key to stop the motor.
If the motor rotation is incorrect, power down the EQ7 drive.
After the power has been turned OFF, wait at least ten minutes until the charge indicator extinguishes
completely before touching any wiring, circuit boards or components.
Using Safety precaution, and referring to Fig.2.23, exchange any two of the three output leads to the motor (U/T1,
V/T2 and W/T3). After the wiring change, repeat this step and recheck motor direction.
