Setting Precautions
To switch command inputs between the Communications Option Card and the control circuit terminals, set the
following constants.
•
Set b1-01 (Reference Selection) to 1 (Control circuit terminal [analog input])
•
Set b1-02 (Operation Method Selection to 1 (Control circuit terminal (sequence inputs])
•
Set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12 function selec-
tion) to 2 (Option/Inverter selection).
Jog Frequency Operation without Forward and Reverse Commands
(FJOG/RJOG)
The FJOG/RJOG command functions operate the Inverter using jog frequencies by using the terminal ON/
OFF operation. When using the FJOG/RJOG commands, there is no need to input the run command.
To use this function, set one of the constants H1-01 to H1-10 (multi-function contact input terminal S3 to S12
function selection) to 12 (FJOG command) or 13 (RJOG command).

Application Precautions
•
Jog frequencies using FJOG and RJOG commands are given priority over other frequency references.
•
When both FJOG command and RJOG commands are ON for 500 ms or longer at the same time, the
Inverter stops according to the setting in b1-03 (stopping method selection).
