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 4.4.23 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 03-07) 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.
