4.4 Basic Parameter Adjustments
144 YASKAWA TM.V1000.01 V1000 Drive Installation & Start-Up Manual (Preliminary 01-19-07)
■ Setting Instructions for Setting a V/f Pattern
1. Set the input voltage for the drive. Refer to Drive Input Voltage Setting
E1-01 on page 129.
2. Select one of the two following V/f patterns:
• Select one of the 15 preset V/f patterns (setting = 0 through E)
• Select the Custom V/f pattern (setting = F)
Note: Parameters E1-04 to E1-10 are set automatically and cannot be individually
adjusted when using one of the preset patterns. When using the custom pattern
(E1-03 = F) parameters E1-04 to E1-10 can be manually adjusted to tailor the V/f
pattern to the desired settings.
3. The parameters listed below are set automatically when using one of the
preset patterns. (E1-03 = 0 to E)
When using a custom V/f pattern, set these parameters as desired:
