E1-01: Input Voltage Setting
Set the input voltage parameter to the nominal voltage of the AC power supply. This parameter adjusts the levels of some
protective features of the drive (overvoltage, Stall Prevention, etc.).
NOTICE: Set parameter E1-01 to match the input voltage of the drive. Drive input voltage (not motor voltage) must be set in E1-01 for
the protective features of the drive to function properly. Failure to comply could result in improper drive operation.

The braking transistor operation levels are valid for the drive internal braking transistor. If an external CDBR braking chopper is used,
refer to the instruction manual of that unit.

V/f Pattern Settings
The drive utilizes a set V/f pattern to determine the appropriate output voltage level for each relative to the frequency
reference.
V/f Pattern Setup for V/f Control
1.
Set the input voltage for the drive. Refer to E1-01: Input Voltage Setting on page

.
2.
Set the V/f pattern. Refer to V/f Pattern Settings E1-04 to E1-10 on page
