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 />
