* 1. These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.
* 2. The factory setting will change when the control method is changed. The open-loop vector 1 factory settings are given.
* 3. E1-11 and E1-12 are disregarded when set to 0.0.
* 4. E1-13 is set to the same value as E1-05 by autotuning.
* 5. The setting range for open-loop vector 2 control is 0 to 66.0 (0 to 132.0 for PRG: 103).
Setting 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.
Setting V/f Pattern
Set the V/f pattern in E1-03 when using V/f control (with or without a PG). 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.

Characteristic
This pattern is used in general applications.
Used when the load torque is fixed, regard-
less of rotation speed, for linear transport
systems.

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