When the AI1 input exceeds the limit, VDO1 becomes ON. At this moment, VDI1
becomes ON and the AC drive receives you-defined fault 1. Then the AC drive reports
Err27 and stops.
•
Decided by A1-06
The VDI state is determined by the binary bit of A1-06. For example, to implement
the function that the AC drive automatically enters the running state after power-on,
perform the following setting:
1) Allocate VDI1 with function 1 "
F
orward RUN (
F
WD)" (A1-00 = 1).
2) Set A1-05 to xxx1: The state of VDI1 is decided by A1-06.
3) Set A1-06 to xxx1: VDI1 is valid.
4) Set
F
0-02 to 1: The command source to terminal control.
5) Set
F
8-18 to 0: Startup protection is not enabled.
When the AC drive completes initialization after power-on, it detects that VDI1 is valid
and VDI1 is allocated with the function of forward RUN. That is, the AC drive receives
the forward RUN command from the terminal. Therefore, The AC drive starts to run in
forward direction.

State selection for AI used as DI
Unit's digit (AI1)
000
0: High level valid
1: Low level valid
Ten's digit (AI2)
0, 1 (same as unit's digit)
Hundred's digit (AI3)
0, 1 (same as unit's digit)
The functions of these parameters are to use AI as DI. When AI is used as DI, the AI state
is high level if the AI input voltage is 7 V or higher and is low level if the AI input voltage is 3
V or lower. The AI state is hysteresis if the AI input voltage is between 3 V and 7 V. A1-10 is
used to determine whether high level valid or low level valid when AI is used as DI.
The setting of AIs (used as DI) function is the same as that of DIs. For details, see the
descriptions of group F4.
The following figure takes AI input voltage as an example to describe the relationship
between AI input voltage and corresponding DI state.
