H Adjusting the V/f Pattern
Normally it isn’t necessary to adjust the V/f pattern with flux vector control. Adjust the V/f pattern when
you want to change the maximum frequency, maximum voltage, base frequency, or minimum output
frequency settings.

Note 2. These voltages are for the 200-V class; Double the voltage for 400-V class Inverters.
Note 3. The
default setting for E1-09 depends on the control mode. The default settings shown in the
table are for flux vector control.
Note 4. The three frequency settings must satisfy the following formula:
E1-04 (F

D Units for V/f Pattern Settings
The units used for V/f pattern frequency settings can be changed when flux vector control has been
selected. This parameter cannot be changed during operation.
