Installing and Operating the SP200 AC Drive
8.2
Check the Direction of Motor Rotation
Important: If any problems occur while the drive is running, refer to chapter 9,
Diagnostics and Troubleshooting.
After verifying that the drive installation is correct, check the direction of rotation of the
motor using the following procedure:
Step 1. Turn off, lockout, and tag AC input power to the unit.
Step 2. Uncouple the driven equipment from the motor, if possible.
Step 3. Set the speed reference signal to minimum speed.
Step 4. Remove the lockout and tag, and turn power on to the unit.
Step 5. Press the
key or supply a start signal.
Step 6. Visually check the direction of shaft rotation. If shaft rotation is correct,
proceed to the next section, Testing the Drive under Load. If shaft rotation is
incorrect, continue to step 7.
Step 7. Turn off, lockout, and tag AC input power to the unit.
Step 8. Wait three minutes after disconnecting power to allow the DC bus to
discharge.
Step 9. Reverse any two of the three motor power leads (U/T1, V/T2, and W/T3).
8.3
Test the Drive under Load
Use the following procedure to test the drive under load:
Step 1. Turn off, lockout, and tag power to the drive.
Step 2. Couple the driven equipment to the motor.
Step 3. Turn power on and start the drive.
Step 4. Run the drive across the required speed range under load.
If the motor does not rotate properly at minimum speed, adjust the auto
torque boost (see parameter P-55) until the desired operation is achieved.
Step 5. If the drive operates the motor properly, record any changes made to
parameter settings in Appendix D.
Step 6. If the drive does not operate the motor properly:
a. Refer to chapter 9, Diagnostics and Troubleshooting.
b. Verify the parameter settings.
!
ATTENTION: The following procedures require rotating parts and/or
electrical circuits to be exposed. Stay clear if the motor must be running.
Disconnect, lockout, and tag the power source if contact must be made.
Failure to observe this precaution could result in severe bodily injury or
loss of life.
