Voltage Upper Limits For 208-240V Class Drives; V/F Pattern Voltage Upper Limit - YASKAWA F7 User Manual

http://www.aotewell.com
This parameter is only available in the V/F or V/F with PG control methods (A1-02 = 0 or 1).
The Drive operates utilizing a set V/F pattern to determine the appropriate output voltage level for each commanded speed.
There are 15 different preset V/F patterns to select from (E1-03 = 0 to E) with varying voltage profiles, base level
(base level = frequency at which maximum voltage is reached), and maximum frequencies.
There are also settings for Custom V/F patterns that will use the settings of parameters E1-04 through E1-13. E1-03 = F selects
a custom V/F pattern with an upper voltage limit and E1-03 = FF selects a custom V/F pattern without an upper voltage limit.
See Fig 5.8 below for the upper voltage limit.
