Note:

Be aware of the following points when manually setting V/f patterns.

•

To set linear V/f characteristics at frequencies lower than

E1-06 [Base Frequency]

, set

E1-07 = E1-09 [Mid A Frequency = Min Output

Frequency]

. In this application, the drive ignores

E1-08 [Mid A Voltage]

•

Set the five frequencies as specified by these rules: Incorrect settings will cause

oPE10 [V/f Data Setting Error]

E1-09 ≤ E1-07 < E1-06 ≤ E1-11 ≤ E1-04 [Min Output Frequency ≤ Mid A Frequency < Base Frequency ≤ Mid B Frequency ≤ Max
Output Frequency]

•

Setting

E1-11 = 0 [Mid B Frequency = 0 Hz]

disables

E1-12 [Min Output Voltage]

. Ensure that the four frequencies are set according

to the following rules;

E1-09 ≤ E1-07 < E1-06 ≤ E1-04

•

When you use

A1-03 [Init Parameters]

to initialize the drive, it will not reset

Input AC Supply Voltage

Sets the drive input voltage.

200 V Class: 230 V, 400 V:

400 V

(200 V Class: 155 to 255 V,

400 V Class: 310 to 510 V)

NOTICE:

Set parameter E1-01 to align with the drive input voltage (not motor voltage). If this parameter is incorrect, the

protective functions of the drive will not operate correctly and it can cause damage to the drive.

Values Related to the Drive Input Voltage

The value set in

E1-01

is the base value that the drive uses for the motor protective functions in

Table 12.29

. With

a 400 V class drive, the detection level changes for some motor protective functions.

This is the protection function enabled in drives with built-in braking transistors. These values show the level that will trigger the
built-in braking transistor. Refer to

V/f Pattern Selection

Sets the V/f pattern for the drive and motor. You can use one of the preset patterns or you can
make a custom pattern.

(Determined by A1-02)

Note:

•

When

A1-02 = 2 [Control Method = OLVector]

, settings

are not available.

•

Set the correct V/f pattern for the application and operation area. An incorrect V/f pattern can decrease motor torque and increase
current from overexcitation.
