Voltage
Set
the Inverter input voltage correctly in E1-01 to match the power supply voltage. This set value will be the
standard
value for the protection function and similar functions.

V/f
Pattern
Set
the V/f pattern in E1-03. There are two methods of setting the V/f pattern: Select one of the 15 pattern
types
(set value: 0 to E) that have been set beforehand, or set a user-defined V/f pattern (set value: F).
The
factory setting for E1-03 is F. The contents of E1-03 when factory-set to F are the same as when E1-03 is
set
to 1.
To
select one of the existing patterns, refer to the following table.
* The
torque is protected by the fully automatic torque boost function, so normally there is no need to use this pattern.
When
you select these patterns, the values of parameters E1-04 to E1-10 are changed automatically. There are
three
types of values for E1-04 to E1-10, depending on the Inverter capacity.

(See
Note)
*
Select
the high startup torque V/f pattern
only
in the following cases.
• The
wiring distance between Inverter and
motor
is large (approx. 150 m min.)
• A
large torque is required at startup (ele-
vator
loads, etc.)
• An
AC reactor is inserted in the Inverter
input
or output.
• You
are operating a motor that is less
than
optimum.
