The function code only in automatic frequency reduction (E2.29) when selecting effective
use.
Feedback value is greater than the given value of frequency converter, inverter frequency
reduction to PID (E2.30) stop frequency, the PID testing number began to count, every PID
detection time (E2.31) a number of times, when the count reaches the PID testing number (E2.32),
the inverter is slowing down. If in the counting process, feedback value is less than the given
value, the inverter directly to accelerate the operation to the set frequency.
E2.31 PID detection time
0s to 3600s
10
☆
PID frequency effectively reduced, used to detect the time of frequency decline
E2.32 PID detection number
10 to 500
20
☆
This function relate to the stop frequency setting of PID, the inverter will decelerate and stop
when the detective time set reach.

Virtual VDI1 ~ VDI5 on the function, are exactly as same as the DI on the control panel, can
be used as a multi-function digital quantity input, the details please refer to the F1.00 ~ F1.09 is

Different from ordinary digital quantity input terminals, virtual VDI state can have two
setting modes which is selected by E3.06.
When selecting VDI state is determined by the state of the corresponding virtual VDO, VDI
is valid or invalid state depending on the VDO output valid or invalid, and VDIx only binding
VDOx(x=1~5).
When choosing VDI state selection function code to set, through the binary bits of E3.05,
respectively determine the state of virtual input terminals.
Example of how to use VDI.
Example 1. Implement following function: “Inverter fault alarm and shuts down when AI1
input exceeds upper or lower frequency” .
Realize by following settings: Set VDI state decided by VDO, set VDI1 function as “ user
defined fault 1” (E3.00=44); set VDI1 terminal state effective mode decided by VDO1
(E3.06=xxx0); set VDO1 output function as “AI1 input exceeds upper & lower frequency”
(E3.11=31); so when AI1 input exceeds upper or lower frequency, VDO1 state is ON, VDI1 input
