Voltage
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.).
NOTE: DRIVE INPUT VOLTAGE
(NOT MOTOR VOLTAGE)
MUST BE SET IN E1-01 FOR
THE PROTECTIVE
FEATURES OF THE DRIVE
TO FUNCTION PROPERLY.
FAILURE TO DO SO MAY
RESULT IN EQUIPMENT

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.
