5.5 E: Motor Parameters
E parameters cover V/f pattern and motor data settings.
◆ E1: V/f Pattern
■ 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 to function properly. Failure to set the correct drive input voltage will result in improper drive operation.
E1-01 Related Values
The input voltage setting determines the undervoltage detection level as well as DC bus levels used by the KEB function
and the overvoltage suppression function.
Note: 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 (E1-03)
The drive uses the V/f pattern that has been set to adjust the output voltage relative to the frequency reference. There are
15 different preset V/f patterns (setting 0 to E) to select from, each with varying voltage profiles, saturation levels
(frequency at which maximum voltage is reached), and maximum frequencies. Additionally, one custom V/f pattern is
available (setting F). The custom V/f pattern requires the user to create the pattern using parameters E1-04 through E1-
10.
■
E1-03: V/f Pattern Selection
The user can select the V/f pattern for the drive and motor from 15 predefined patterns, or create a custom V/f pattern.
