The V/f pattern settings can be divided into two categories: the 15 preset patterns (settings 0 through E)
and custom user-set patterns (setting F). The factory default setting for E1-03 is “F” (user-defined V/f
pattern), but the contents of this setting are actually the same as setting “1.”
H
Selecting a Preset V/f Pattern (Settings “0” through “E”)
Refer to the following table when selecting one of the 15 preset patterns.

Note 1. Select a high starting torque V/f pattern only in the following cases:
S
The wiring distance between the Inverter and motor is relatively large (greater than 150 m).
S
A large torque is required at startup (such as heavy axis loads).
S
An AC or DC reactor is connected to the Inverter’s input or output.
