APPENDIX 6 ROTATION DIRECTION OF MOTOR

If the standard connection is used for the output terminals of the main circuit, the motor rotates coun-
terclockwise as viewed from the load side of the motor in a forward operation.

To rotate the motor clockwise in a forward operation, use the following procedures to change the
connection of the terminals and the setting of the constants, check the motor speed detection, and
adjust the PG zero-pulse.

(1) Reconnect the output terminals of the main circuit:

Connect motor lead V to output terminal W.

Connect motor lead W to output terminal V.

Do not change the connection between lead U and output terminal U.

(2) Modify the setting of constant F1-05 (For flux vector control with PG)

Set F1-05 (PG rotation direction) to 0.

(3) Check the motor speed detection (For flux vector control with PG)

Refer to page 48.

(4) Adjust the PG zero-pulse (For flux vector control with PG)

Refer to page 49.

Do not change the connection of the PG cable.

If the rotation direction of the motor is set to clockwise for a forward operation (Refer
to Fig.A-2), change the connection of the output terminal of the main circuit to the
standard connection and then proceed to steps (2) through (4).
