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

V/F Pattern Selection
V/F 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.

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. Always ensure that the
four frequencies are set in the following manner:
E1-04
≥ E1-12 ≥ E1-06 > E1-07 ≥ E1-09
E2-04 is automatically set during Auto-Tuning.
