When the 12 Power Switch is turned on, the rotation direction made when the switch was last
turned off are restored. Special attention should be given to the rotation direction.

8. Error Code

When the motor is stopped due to some trouble such as a failure, overload, wire breakage or
misuse, Speed Display displays the error code for checking the status of the unit and
understanding the cause of the trouble easily.
