Fig 6.63 User-Set V/f Pattern
If one of the custom V/f patterns is selected, then parameters E1-04 through E1-13 will determine the V/f pattern.
„ 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)

IMPORTANT
When a factory Initialization is performed, the setting of E1-03 is unaffected but the settings of E1-04
through E1-13 are returned to their factory default settings.
