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
frequency command, and use terminals S1, S2 or communication terminal RS-485 to control the operation
command.
Input Mode Frequency Reference / Run/Stop Command Source
ON Communication
- Frequency reference and run/stop command control via communication
(RS-422/RS-485).
OFF Terminal
- Frequency reference source from AI1 / AI2 input (00-05=1) and
Run-Stop command from terminals S1 / S2 (00-02=1).
Figure 4.3.20 Remote mode operation selection
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 03-05) to 28 (Operation selection of remote mode)
03-0X =24: PLC Input
It is required to match Drive Link program. Ladder diagram is edited in the PLC program. When the
message output is conducted, this message will be sent to the inverter.
03-0X =26: 3-Wire Sequence (Forward/ Reverse Command)
When the digital input terminals (S3~S6) is set to 26, terminal S1 and S2 will become the run command
and stop command. Refer to Fig.4.3.2.
03-0X =29: Jog Frequency Selection
When 00-18 (Jog Frequency) is set up, the inverter depends on this frequency for command when it is ON.
