Setting the V/f Pattern
If E1-03 is set to F the V/f pattern can be set individually using the parameters E1-04 to E1-10. See Fig 5.23
for details.

Setting Precautions
When the setting is to user-defined V/f pattern, beware of the following points:
• When changing control method, parameters 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)
To set the V/f characteristics linear, set E1-07 and E1-09 to the same value. In this case, E1-08 will be ignored.
