Frequency
These parameters are only applicable
when V/f Pattern Selection is set to
Custom (E1-03 = F or FF). 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. Be sure that the four
frequencies are set in the following
manner or else an OPE10 fault will
occur:
E1-04 (FMAX)
≥ E1-11 ≥ E1-06 (FA)
> E1-07 (FB)
≥ E1-09 (FMIN)
Note: Setting parameter E1-01 to
zero is also acceptable
