Checking the Speed Reference
Use the following procedure to check the speed reference:
1. Uncouple the driven equipment from the Motor Section, if possible.
2. Turn power on to the unit.
3. Set the operator speed reference signal to zero. Note that when the unit is powered
up the first time, it uses the factory-set minimum speed setting as the speed
reference.
4. Standard units: Use the speed potentiometer or other user-supplied external
speed reference device.
5. Local operator control units: Use the
key to decrease the speed reference.
6. Press the user-installed Start button (Section 7.6) or the green
key on local
operator control units.
7. Vary the speed reference while running the motor unloaded across the speed
range. Use a handheld tachometer to check the speed.
8. If the motor operates satisfactorily, proceed to Step 10.
If the motor does not operate satisfactorily, continue with Step 9.
9. If the motor does not operate satisfactorily:
a. Check that the speed reference is wired correctly. See Section 7.5, Wiring
the Speed Reference.
b. If the speed reference is correct, and the motor does not operate
satisfactorily, refer to Chapter 8, Verify the Setup and Adjust the Switches
if Required.
10. If the motor operates satisfactorily:
a. Press the user-installed Stop button (Section 7.6) on standard units or the
red
key on the local operator control units.
b. Remove power from the unit.
c. Couple the driven equipment to the Motor Section.
ATTENTION: The following procedures require rotating parts and/or
electrical circuits to be exposed. Stay clear if the unit must be running.
Disconnect, lockout, and tag the power source if contact must be made.
Failure to observe these precautions could result in severe bodily injury
or loss of life.
