Setting Set to the nominal voltage of the
incoming line. Sets the maximum and
base voltage used by preset V/F
patterns (E1-03 = 0 to E), adjusts the
levels of Drive protective features
(e.g. Overvoltage, braking resistor
turn-on, stall prevention, etc.).

V/f Pattern
Selection Set to the type of motor being used
and the type of application.
The Drive operates utilizing a set
V/F pattern to determine the
appropriate output voltage level for
each commanded speed. There are
15 different preset V/F patterns to
select from (E1-03 = 0 to E) with
varying voltage profiles, base
levels (base level = frequency at
which maximum voltage is
reached), and maximum
frequencies. There are also settings
for Custom V/F patterns that will
use the settings of parameters
E1-04 through E1-13. E1-03 = F
selects a custom V/F pattern with
an upper voltage limit and
E1-03 = FF selects a custom V/F
pattern without an upper voltage
limit.
