Setting Drive Input Voltage E1-01
Setting Range:
155.0V to 255.0V (200-240V Models)
310.0V to 510.0V (380-480V Models)
Factory Defaults: 240.0V (200-240V Models)
480.0V (380-480V Models)
Set the Input Voltage parameter (E1-01) to the nominal voltage of the connected AC power supply. This parameter
adjusts the levels of some protective features of the Drive (i.e. Overvoltage, Stall Prevention, etc.). E1-01 also serves
as the Maximum/Base Voltage used by the Preset V/Hz curves (E1-03= 0 to E).
E1-03 V/f Pattern Selection
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 with varying voltage profiles, saturation levels (fre-
quency at which maximum voltage is reached), and maximum frequencies.
There are also settings for Custom V/f patterns that will allow the programmer to manually set (“Customize”) the V/f
pattern using parameters E1-04 through E1-13.
Using parameter E1-03, the programmer can select one of the preset V/f patterns or chose between a custom V/f pat-
tern with an upper voltage limit (E1-03= “F: Custom V/F”) and a custom V/f pattern without a voltage limit (E1-03=
“FF: Custom w/o limit”).
WARNING
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 DAMAGE AND/OR PERSONAL INJURY.
