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
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.
