nSetting Inverter Input 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.
nSetting 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.
• 0.4 to 1.5 kW V/f pattern
• 2.2 to 45 kW V/f pattern
• 55 to 300 kW V/f pattern
The characteristics diagrams for each are shown in the following pages.
Characteristic Application Set Value Specifications
Constant Torque
Characteristic
This pattern is used in general applications.
Used when the load torque is fixed, regard-
less of rotation speed, for linear transport
systems.

This pattern is used for loads with torque
proportional to two or three times the rota-
tion speed, such as fans and pumps.

High Startup
Torque (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.
