RS485). Use parameter 00-05 (Main frequency command source selection) and 00-02 (Run command selec-
tion) to select the remote source.
Note:
In 3-wire operation terminal S1 and S2 are reserved for run/stop operation and the Local / Remote function can only be
set to digital input terminals S3 to S8 (03-02 to 03-07).
Note:
To switch between local and remote the inverter has to be stopped.

03-0X =28: Remote mode selection
Switch between terminal source and communication (RS-422/RS-485) source for frequency reference and
operation command.
In Remote mode, indicators of SEQ and REF are on; you can use terminals AI1 and AI2 to control the frequen-
cy command, and use terminals S1, S2 or communication terminal RS-485 to control the operation command.
Input
ON Communi-
OFF Terminal
To switch the frequency reference and operation command input between communication RS-485 and control
terminals the following parameters have to be set:
1. 00-05=1 (use control terminal AI1 or AI2 as reference frequency source)
2. 00-02=1 (use control terminal S1 or S2 for operation command)
3. Set one of the digital input terminals (03-02 to 03-07) to 28 (Operation selection of remote mode)
03-0X =29: Jog Frequency Selection
When jog frequency selection is on, the inverter will depend on the parameter 00-18 (jog frequency) as the
command.
03-0X =30: Acceleration/ Deceleration Time Selection 2
When accel./ decel. time selection 2 is ON, the inverter will depend on the parameter 00-16 acceleration time 2
and the parameter 00-17 deceleration time 2.
03-0X =31: Inverter overheat warning
When input is active the inverter displays warning message "OH2" and continues operation. Deactivating the
input reverts back to the original display. Warning message does not require resetting the inverter.
03-0X =32: Sync command
Selects between frequency reference source from pulse input or frequency reference source selected by pa-
rameter 00-05. Refer to page 4-116 for more information.
