Input Terminal Functions
This section explains input terminal functions, which set operating methods by switching functions for the
multi-function contact input terminals (S3 to S12).
Temporarily Switching Operation between Digital Operator and Control
Circuit Terminals
You can switch the Drive run command inputs and frequency reference inputs between local (i.e., Digital
Operator) and remote (input method using b1-01 and b1-02).
You can switch between local and remote by turning ON and OFF the terminals if an output from H1-01 to
H1-10 (multi-function contact input terminal S3 to S12 function selection) has been set to 1 (local/remote
selection).
To set the control circuit terminals to remote, set b1-01 and b1-02 to 1 (Control circuit terminals).

You can also perform local/remote switching using the LOCAL/REMOTE Key on the Digital Operator. When
the local/remote function has been set in the external terminals, the LOCAL/REMOTE Key function on the
Digital Operator will be disabled.
