Select the Potentiometer for Speed Command - The motor speed may be controlled from the
following sources:
Potentiometer on front panel keypad (if present)
Control terminals
Remote panel
Then follow the steps in the table below to select the potentiometer for the speed command (the
table resumes action from the end of the previous table).
Select the Keypad for the RUN Command - The RUN command causes the inverter to accel-
erate the motor to the selected speed. You can program the inverter to respond to either the
control terminal signal or the keypad RUN key. Follow the steps in the table below to select the
front panel RUN key as the source for the RUN Command (the table resumes action from the
end of the previous table).
NOTE: When you press the STR key in the last step above (and the display = 02), the Run
Enable LED above the RUN switch on the keypad will turn ON. This is normal, and does not
mean the motor is trying to run. It means that the RUN key is now enabled.
DO NOT press the RUN key at this time—finish out the programming exercise first.
