Chapter 4 Explanation of Functions<br />

4.2.4 Frequency source setting<br />

The frequency source setting function allows you to select the method to<br />

input the frequency-setting command.<br />

Motor rotation direction is inverted when -10 to 0V is given as frequency command to 02-L terminals.<br />

Item Function code Data Description<br />

(00)<br />

(Valid only when the OPE-SR is used)<br />

Use the control provided on the digital operator to set the frequency.<br />

01<br />

Input the frequency-setting command via a control circuit terminal (0-L,<br />

OI-L, or O2-L).<br />

02<br />

Use the digital operator (function "F001") or remote operator to set the<br />

frequency.<br />

Input the frequency-setting command via an RS485 communication<br />

03<br />

terminal.<br />

Frequency<br />

Input the frequency-setting command from the board connected to<br />

source<br />

A001 04<br />

optional port 1.<br />

setting<br />

Input the frequency-setting command from the board connected to<br />

05<br />

optional port 2.<br />

06<br />

Use the SJ-FB to input the frequency-setting command as a pulse train<br />

(see 4.2.21)<br />

07<br />

Use the SET-Freq command of the easy sequence function as the<br />

frequency-setting command.<br />

10<br />

Use the operation result of the set frequency operation function as the<br />

frequency-setting command. (see 4.2.12)<br />

4.2.5 Run command source setting<br />

The run command source setting function allows you to select the<br />

method to input operation commands (to start and stop the motor).<br />

As the operation commands via control circuit terminals, turn the<br />

FW signal (for forward operation) or RV signal (for reverse<br />

operation) on and off to start and stop the motor, respectively.<br />

(Note that the factory setting assigns the FW signal to intelligent input terminal [8].)<br />

To switch each intelligent input terminal between a and b contacts, specify each terminal with function<br />

"C011" to "C019", and then perform input a/b (NO/NC) selection for each terminal.<br />

When using the digital operation for the inverter operation, specify the desired motor operation direction<br />

with function "F004", and use the RUN and STOP/RESET keys to start and stop the motor, respectively.<br />

If the start commands for both forward and reverse operations are input at the same time, the inverter will<br />

assume the input of a stop command.<br />

Item Function code Data Description<br />

01<br />

Input the start and stop commands via control circuit<br />

terminals (FW and RV).<br />

Input the start and stop commands from the digital or<br />

02<br />

Run command<br />

remote operator.<br />

A002<br />

source setting<br />

Input the start and stop commands via RS485<br />

03<br />

communication terminals.<br />

04 Input the start and stop commands from option board 1.<br />

05 Input the start and stop commands from option board 2.<br />

Terminal [FW]<br />

C019<br />

00 a (NO) contact<br />

active state C011 to C018 01 b (NC) contact<br />

Note 1: If function "31" (forcible operation) or "51" (forcible-operation terminal) is assigned to an intelligent input<br />

terminal, the settings made with functions "A001" and "A002" will be invalidated when the said intelligent<br />

input terminal is turned on and those methods to input frequency-setting and operation commands which are<br />

specified for the said terminal will be enabled.<br />

Note 2: On the remote operator (SRW) being used to operate the inverter, pressing the REMT (remote) key enables<br />

you to input both frequency-setting and operation commands from the remote operator.<br />

Note3: When the DeviceNet option board (SJ-DN) is used, A002 is not needed to be changed from default because<br />

the run command source is automatically set via DeviceNet. (In case it is changed, it is to be set as 01, 02 or<br />

03.)<br />
