NOTE

4.2 Applying Power to the Frequency Converter

 through in

this chapter concludes the procedures for applying power
to the frequency converter, basic programming, set-up,
and functional testing.

4.5  System Start Up

The procedure in this section requires user-wiring and
application programming to be completed. See for
application set-up information. The following procedure is
recommended after application set-up by the user is
completed.

CAUTION

MOTOR START!

Ensure that the motor, system, and any attached
equipment is ready for start. It is the responsibility of the
user to ensure safe operation under any condition. Failure
to do so could result in personal injury or equipment
damage.

1.

Press [Auto On].

2.

Ensure that external control functions are
properly wired to the frequency converter and all
programming is completed.

3.

Apply an external run command.

4.

Adjust the speed reference throughout the speed
range.

5.

Remove the external run command.

6.

Note any problems.

If warnings or alarms occur, see
