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).
