Input Voltage Setting

E1-01 Input Voltage Setting
Setting Range: 155.0V to 255.0V (240V Models)
310.0V to 510.0V (480V Models)
Factory Defaults: 230.0V (240V Models)
460.0V (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, Built-in Braking Transistor Turn-on, Stall Prevention, etc.).
E1-01 also serves as the Maximum/Base Voltage used by the Preset V/F curves (E1-03=0 to E).
DRIVE INPUT VOLTAGE (NOT MOTOR VOLTAGE) MUST BE SET IN E1-01 FOR THE PRO-
TECTIVE FEATURES OF THE DRIVE TO FUNCTION PROPERLY. FAILURE TO DO SO
MAY RESULT IN EQUIPMENT DAMAGE AND/OR PERSONAL INJURY.
