detection time
Feedback disconnection detection value: the detected value is relative to the full
scale (100%), the system has been detecting PID feedback, when the feedback value is
less than or equal to the feedback disconnection detection value, the system starts to
detect timing. When the detection time exceeds the feedback disconnection detection
time, the system will report PID feedback disconnection fault (E.PId) .

The function of virtual VDI1 to VDI5 is same as DI on the control panel, they can
be used as a multi-functional digital inputs, please refer to the introduction of F1.00 to
F1.05 for detailed settings.

It is different from ordinary digital input terminal, the state of virtual VDI has two
kinds of setting, the selection depends on E3.06.
If the state of selection VDI is determined by the state of corresponding virtual
VDO, the availability of VDI depends on the valid or invalid VDO output, and VDIx
only binds VDOx (x is 1 to 5) .
if the state of selection VDI is set by the function code, the status of virtual input
terminals can be determined through E3.05 binary bits respectively.
The following example illustrates the use of VDI. Example 1, to achieve the
following function: "Upon arrival of running frequency, the inverter will perform free
stop" Using the following settings method: set that the VDI state selection depends on
VDO, set VDI1 function as "free stop" (E3.00 = 8) ; set that VDI1 terminal active
mode depends on VDO1 (E3.06 = xxx0) ; set VDO1 output function as "Frequency
Arrival" (E3.11 = 5) ;
When the inverter reaches the set frequency, the state of VDO1 is ON, at the time
VDI1 input terminal status is valid, if the inverter VDI1 receives the command of free
stop, the inverter will perform free stop.
Example 2, to achieve the following function: " the inverter is powered on, it
automatically enters the running state." Using the following settings: the function code
E3.05 is used to set the state of VDI, set VDI1 function as "Forward Run" (E3.00 = 1) ;
set that VDI1 terminal active mode depends on function code (E3.06 = xxx1) ; set
VDI1 terminal status as valid (E3.05 = xxx1) ; set command source as terminal control
(F0.04 = 1) ; set start protection option for "terminal command" (F7.09=1);
After the initialization of inverter is completed, it is detected that VDI1 is valid
and this terminal corresponds to the forward run, which is equivalent to that the
