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

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.
