You can control the inverter through communication with a higher controller (PLC or PC) by using terminal RS485 (+S,
-S) on the terminal block if you set DRV-06 Cmd Src at Int 485. For details, see Communication Functions, Chapter

Caution
Local/remote By-pass operation might cause a problem with the device such as
interruption during operation if it is improperly used, so it is highly recommended that
you use it only when necessary.
In case of operation by other than using the keypad (terminal block or communication), you can use it when checking
the operation or body of the inverter or conducting manual switching operation using the keypad in the field in case of
an emergency.
1) Definition of Local: Local refers to the function of transforming all the operating, frequency and torque commands for
them to be operated by using the keypad in order to enable the keypad to carry out all operation. In such a case, JOG
command is ignored (When RUN Enable is set in the multi-function terminal, operation is possible with it on).
2) Definition of Remote: Remote refers to the operation of the inverter by the previously set operating and frequency
commands of the inverter in communication or sequence when it is set at communication or sequence respectively.
3) CNF-42 Multi-Key Sel: If you set at No. 1 Local/Remote, the signal R emerges on the keypad status display and the
multi-function keys operate in local/remote functions. When R is seen on the keypad status display, you are in the
Remote Operation Mode, which operates by the previously set parameters without any change in the operation. If you
want Local Operation Mode, with R displayed in the keypad status display, press the multi-function key and R turns
into L and you can operate the inverter with FWD and REV keys on the keypad setting. If you press the multi-function
key one more time, R is displayed and the inverter operates by the method selected in DRV-06 Cmd Source.
