Input Terminal Functions
This section explains input terminal functions, which set operating methods by switching functions for the
multi-function digital input terminals (S3 to S12).
‹ Temporarily Switching Operation between Digital Operator and Control
Circuit Terminals
Switch the MxC Run Command inputs and frequency reference inputs between local (i.e., digital operator)
and remote (input method using b1-01 and b1-02).
Switch between local and remote by turning on and off the terminals if an output from H1-01 to H1-10 (Termi-
nal 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).

INFO
Switch local or remote 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 dis-
abled.
