CONFIGURING THE SCF DRIVE
Entering Program Mode:
To access the parameters, press the Mode button. This will
activate the password prompt. The display will read "00" and the
right-hand decimal point will be blinking. Use the  and  buttons
to scroll to the password value (the factory default password is 225)
and press MODE to enter.

Press Mode to enter password
Once the PROGRAM mode is accessed, use the  and  buttons to
scroll to the desired parameter number, and press the Mode button
to see the parameter setting. Use the  and  buttons to change
the parameter setting and press Mode to store the new setting.
Connections:
Below is a sample wiring diagram for two-wire start/stop control. The
drive is ready to use right out of the box, with these simple control
wiring connections; no parameter adjustments are required. Speed
is controlled from the  and  buttons on the front of the drive.
