VD560 Series Inverter User Manual Parameter Description

beyond the upper and lower limit, frequency inverter fault alarm and stop", can use the following
setting method:
Set VDI1 function to "user-defined failure 1" (b1-00 = 50);
Set VDI1 terminal valid state model for determine by VDO1 (b1-05 = xxx0);
Set VDO1 output function as "AI1 input beyond the upper and lower limit" (b1-11= 37);
When AI1 input beyond the upper and lower limit, the VDO1 output is ON state, the VDI1 input
terminal state is valid, inverter VDI1 receives the user-defined failure 1, the inverter will fault alarm Err.
35 and stop.
Example 2: when selecting function code b1-06 set VDI state, to complete the following functions:
"after inverter power on, automatically enter the running state", can use the following setting method:
Set VDI1 function to " forward running " (b1-00=1);
Set VDI1 terminal valid state mode is setting for function code (b1-05=xxx1);
Set VDI1 terminal status for valid (b1-06=xxx1);
Set the command source for "terminal control" (F0-01=1);
After inverter power on and finished initialization, detect VDI1 is effective, and the terminal
corresponding to forward running, equivalent to a frequency inverter receives a terminal forward
running command, frequency inverter immediately began to forward running.

As the group function code is used to AI used as DI, when AI used as DI, when the AI input voltage is
greater than 7V, AI terminal state for high level, when the AI input voltage is lower than 3V, AI terminal
state for low level. Between 3V~7V for hysteresis A1-10 when used to determine the AI as DI, AI high
level state for valid state, or the low level for valid state.
As for AI as the function set of DI, same as the ordinary DI settings, please refer to the instructions of
F5 group related DI setup.
The following figure is take AI input voltage as an example, explaine the relationship between AI input
voltage and the corresponding DI state.
