factory setting
5－7: Frequency source selection 1－3.
• Up to 2
n
frequency reference sources can be switched through terminal logic combination
setting n (the maximum n is 3). Refer to the below table.
• Up to 8 frequency reference sources can be switched through selecting 3 terminals.
• Up to 4 frequency reference sources can be switched through selecting 2 terminals.
Terminal 3 Terminal 2 Terminal 1 Selection
0 0 0 Hold
0 0 1 Display panel digital setting
0 1 0 Terminal digital setting
0 1 1 SCI communication digital setting
1 0 0 Analogue value setting
1 0 1 Terminal pulse setting
1 1 X Hold
8: AI to be the frequency source.
• If the setting is 8, the frequency reference source can be forcibly switched to analogue setting.
• The priority of frequency sources is shown below:
AI frequency source > multi-step frequency terminal 1, 2, 3 and 4(multi-function terminal is No.
13,14, 15, 16 function) > frequency setting terminal 1,2 and 3(multi-function terminal is No. 5,6,7
function) > frequency source defined by F00.10.
9,10: Run command source selection 1, 2.
• In the below table there are 4 kind control modes selected by the different logic combinations of
terminals 1 and 2.
Terminal 2 Terminal 1 Selection
0 0 Hold the control mode
0 1 Display panel control mode
1 0 Terminal control mode
1 1 SCI communication control mode
• The inverter can accept that run command source switch changes while running, but only at
stop status all switches can be enabled.
11: Terminal control mode to be the run command source.
• When this terminal function is enabled, the run command source will be forcibly switched to the
terminal control mode.
• The priority of frequency selection is below:
Terminal control mode to be the run command source > Display panel’s M key achieves local
and remote switching function (F00.12 = 1) > Run command source selection terminal 1and 2
(multi-function terminal is No. 9,10 function) > Run command source defined by F00.11.
• The modification of run command source is enabled only at stop.
12: External stop command input.
• When enabled, the inverter stops according to F02.13 (stop mode selection). It is valid for all
command source.
