According to the preceding figure
,
when the running frequency of the AC drive is set by
means of communication
(
P0
-
01
=
8
)
and reverse control is enabled
(
P5
-
09
=
0
),
the AC
drive instructs the reverse direction if the set frequency Fs is a negative value
.
If the give running command is reverse rotation or the set frequency is a negative value
,
but
reverse control is disabled
(
P5
-
09
=
1
),
the AC drive will run at 0 Hz and has no output
.
In some applications where reverse rotation is prohibited
,
do not change the rotating
direction by modifying the function codes because the function codes will be restored once
the AC drive restores the default settings

9 Setting the Fixed Length Control Mode
The VDF730 has the fxed length control function
.
The length pulses are sampled by the DI
allocated with function 25
(
Length count input
).
The
"
Actual length
" (
P7
-
06
)
is obtained by
dividing the number of pulses sampled by the value of P7
-
07
(
Number of pulses per meter
).
If the actual length is larger than the
"
Set length
" (
P7
-
05
),
the multifunctional DO terminal
becomes ON
.
In the process of fxed length control
,
the length can be reset by means of the DI terminal
allocated with function 26
(
Length reset
).
The related setting is shown in the following fgure
.
