Ten’s digit: DI7, same as above
Hundred’s digit: DI8, same as above
Thousand’s digit: DI9, same as above
Used to set the valid state model of digital quantity input terminal.
When selection for high level is valid, the corresponding DI terminal is valid connected with the COM,
and is invalid disconnection.
When selection for low level is valid, the corresponding DI terminal is invalid connected with the COM,
and is valid disconnection.

DI Filter Time
0.000s~1.000s
0.010s
○
Set the software filter time of DI terminal state. If the input terminal of the usa occasion is easy to be
interfered an caused by the wrong action, the parameter can be increased to enhance the
anti-interference ability. But the filter time increases can cause DI terminal response slow.

○
Used to set the terminal UP/DOWN to adjust the setting frequency, the speed of frequency change,
that is the frequency variation per second.
When F0-15 (frequency decimal point) is 2, the value range is from 0.001Hz/s to 65.535Hz/s.
When F0-15 (frequency decimal point) is 1, the value range is from 0.01Hz/s to 655.35Hz/s

0x321
○
The unit’s digit and ten’s digit of function code are used to select respectively, the analog input AI1,
AI2, AI3 (expansion card) corresponding set curve, each analog input can choose any one of 5 kinds
of curves.
Curve 1, 2, 3 are 2 point curve, set in the F5 group function code, and the curve 4 and 5 are 4 points,
need to set in the function code in group b2.
VD500 inverter standard unit provides 3 way analog input port, one AI3 on the expansion card.
