Step 10 - Set the Operating Speed
Before starting the unit, set the operating speed as follows:
For standard units: Use the speed potentiometer or other user-supplied external
speed reference device.
For local operator control units: As shipped from the factory, the local operator
control unit receives its speed reference from the keypad. Use the key to increase
the speed reference and the key to decrease the speed reference.
To use the analog input terminals for the speed reference, setup switch 2 (Speed
Reference Select) must be in the ON position. In this case, the keys are not
used. Refer to section 8.3.2 for more information.
At subsequent power ups, the unit will use the last speed reference setting selected
before power was removed.
Important: If speed is erratic or not as expected, verify that only one of the speed reference
inputs (0 to 10 VDC or 4 to 20 mA) has been wired.
