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.

s (E1
)
The drive uses a V/f pattern to adjust the output voltage relative to the frequency reference. There are 15 different predefined
V/f patterns (setting 0 to E) from which to select, 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) that
requires the user to create the pattern using parameters E1-04 through E1-10.

Choose the V/f pattern that best meets the application demands from the table below. These settings are available only in
V/f Control modes. Set the correct value to E1-03. Parameters E1-04 to E1-13 can only be monitored, not changed.
Note:
1.
Setting an improper V/f pattern may result in low motor torque or increased current due to overexcitation.
2.
Drive initialization does not reset parameter E1-03.
