Table 5.6 lists the factory settings of V/F patterns when open loop vector or flux vector control method is selected
(A1-02 = 2 or 3).
Fig 5.9 V/F Pattern Parameters
Parameters E1-07, E1-08, E1-10, E1-11, and E1-12 are accessible through the Programming Menu.
To set up a custom V/F pattern, program the points shown in the diagram below using parameters E1-04 through
E1-13. Be sure that the following condition is true: E1-09
≤ Ε1−07 < Ε1−06 ≤ Ε1−11 ≤ Ε1−04
