7.2 Using the basic functions

7.2.1 Frequency source setting and Output frequency setting

(1) Frequency source setting

The frequency source setting function allows you to select the method to input the frequency-setting

command.

Item Function code Data Description

Frequency

source

setting

A001

A201

(Valid only when the NES1-OP, OPE-SR/SRmini is used)

Use the control provided on the digital operator to set the frequency.

Input the frequency-setting command via a control circuit terminal

(O/OI-L).

Use the digital operator (function "F001") or remote operator to set the

frequency.

03 Input the frequency-setting command via a Modbus communication.

Use the operation result of the set frequency operation function as the

frequency-setting command.

(2) Output frequency setting

The output frequency setting function allows you to set the inverter output frequency.

You can set the inverter output frequency with this function (F001) only when you have specified "02" for

the frequency source setting (A001).

(If the setting of function "A001" is other than "02", function "F001"

operates as the frequency command monitoring function.)

The frequency set with function "F001" is automatically set as the Multispeed frequency setting (A020). To

set the second and third multispeed s, use the multispeed frequency setting, 2nd motor, function (A220)

and multispeed frequency setting, or use function "F001" for the setting after turning on the SET signal. For

the setting using the SET signal, assign the SET function (08) to intelligent input terminals.

If the set output frequency is used as the target data for the PID function, PID feedback data will be

displayed in percent (%). ("100%" indicates the maximum frequency.)

Item Function code Range of data Description

Output frequency setting F001

0.0, start frequency to

maximum frequency,

1st/2nd motors (Hz)

The frequency set with F001 is equal to the

setting of A020.

The second control frequency set with F001

is equal to the setting of A220.
