Notes:
1) The 'Quick Setup Function' sets the motor speed lower than the frequency command in case of
an instantaneous power failure. If this has an adverse effect on the machine, change it by setting
manually.
Quick Setup Parameters
The set values differ with the source voltage rating of the motor as shown below:
50 Hz motor: Set

to 1.
60 Hz motor: Set

Select a suitable source voltage for the motor. Improper voltage selection
could result in rotation failure or, in the worst case, the motor could be
damaged.
The automatic environment settings are as shown on page 31.
