•LOCAL/REMOTE Control I
Remote Control
Run command and frequency command is performed through control circuit input or
OFF
RS-485 communication port. (It will be set by the combination of settings of Sn-04
and Sn-05.) The REMOTE-REF，SEQ LED light is ON.
Local Control
ON Run command and frequency command is performed through digital operator. The
REMOTE-REF，SEQ LED light is OFF.
•To change the operation mode from LOCAL to REMOTE mode is effective only when the
inverter is in STOP mode.
•LOCAL/REMOTE Control II
Remote Control
Run command and frequency command is performed through control circuit input or
OFF

and Sn-05.) The REMOTE-REF，SEQ LED light is ON.
Local Control
ON Run command and frequency command is performed through control circuit terminal.
The REMOTE-REF，SEQ LED light is OFF.
•To change the operation mode from LOCAL to REMOTE mode is effective only when the

•RS-485 Communication Application
•The multi-function input terminals
terminals of PLC with the command communicated through the RS-485 port.
(Please refer to the '7200MA RS-485 MODBUS/PROFIBUS APPLICATION MANUAL'.)
•PG-Less Speed Control Action
•Reset Integration of Speed Control with PG (Setting : 27)
•When PG feedback is used, the integral control (to add the PG feedback
compensation) can be disabled or enabled from the external terminals. And, user
can use the external terminals to clear the integral value.
