Individual Functions
6-127
When E1-03 is set to F (User-defined V/f pattern), you can set constants E1-04 to E1-10. If E1-03 is set to
anything other than F, you can only refer to constants E1-04 to E1-10. If the V/f characteristics are linear, set
E1-07 and E1-09 to the same value. In this case, E1-08 will be ignored.

Setting Precautions
When the setting is to user-defined V/f pattern, beware of the following points.
• When changing control method, constants E1-07 to E1-10 will change to the factory settings for that
control method.
• Be sure to set the four frequencies as follows:
E1-04 (FMAX) ≥ E1-06 (FA) > E1-07 (FB) ≥ E1-09 (FMIN)
