Before running the frequency converter, check the motor
rotation.
1. Press [Hand].
2.
Press [
3. Check that the speed shown is positive.
4. Verity that the wiring between the frequency

3.6 Local-control Test

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

] for positive speed reference.
When parameter H-48 Clockwise Direction
is set to [0] Normal (default clockwise):
a. Verify that the motor turns
clockwise.
b. Verify that the keypad
direction arrow is clockwise.
When parameter H-48 Clockwise Direction
is set to [1] Inverse (counterclockwise):
a. Verify that the motor turns
counterclockwise.
b. Verify that the keypad
direction arrow is counter-
clockwise.
NOTICE
The Hand key on the keypad provides a local start
command to the frequency converter. The [Off] key
provides the stop function.
When operating in local mode, the up and down keys on
the keypad increase and decrease the speed output of
the drive. The left and right keys move the display cursor
in the numeric display.
