Setting the V/f Pattern

In V/f Control Method, the MxC input voltage and the V/f pattern can be set as the need arises.

„

Related Parameters

* 1. Values appearing in this table are for a 200 V class MxC. Double values when using a 400 V class MxC.
* 2. The default will change when the control method is changed. The Open Loop Vector defaults are given.
* 3. E1-11 and E1-12 are disregarded when set to 0.0.
* 4. E1-13 is set to the same value as E1-05 by Auto-Tuning.

To set V/f characteristics in a straight
line, set the same values for E1-07 and
E1-09. In this case, the setting for E1-08
will be disregarded.
Always ensure that the four frequencies
are set in the following manner:
E1-04 (FMAX)

≥ E1-06 (FA) > E1-07

(FB)

≥ E1-09 (FMIN)
