1.
The setting shown are for 208-240Vac Drives. The values will double for 380-480Vac Drives.
2. These default values are for open loop vector or flux vector control methods (A1-02 = 2 or 3)
Max Voltage E1-05
Mid Voltage B E1-12
Base Voltage E1-13
Mid Voltage A E1-08
Min Voltage E1-10
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
