Motor drive feed description
1.
Filling control mode is set as " Motor Drived (1 limit)" mode to control feeding door
ONOFF: Involved I/O Functions are:
Filler Open (Motor) (O21), Filller Close (Motor)
(O22), Filler Gate Closed Pos. (I25)
Take coarse and fine feed process as example:
●
coarse feed process:
（
O21
）
gate open signal output valid,valid time is
“
Feed Gate Open Timer(Co-F)
”
, start coarse feed process.
●
fine feed process
：
When material weight in hopper
≥
Target-Co-Feeding Remains
，
O22
gate close signal output valid
，
valid time is
“
Feed Gate Open Timer(Co-F) -
Feed Gate Open Timer(Fi-F)
”
.
●
Feed close
：
When material weight in hopper
≥
Target-Free fall
，
O22
gate close
signal output valid, till detect Feeding Gate Closed
（
I25
）
.
※
Note
：
If close process timer exceed filler gate close Overtime, controller still
undetect Filler Gate Closed Pos.
（
I25
）
,then controller will stop output Filller Close
signal
（
O22
）
and alarm. After clear alarm
，
continue output the gate close signal.

Motor drive discharge process description
1.
“
DISC Gate Driver Mode
”
set to
“
Normal Motor(One Pos.)
”
to control discharge
：
involved
I/O Function are
：
DISC Gate Open
（
motor
）（
O23
）
, DISC Gate Close
（
motor
）
(O24),
DISC Gate Closed Pos.
（
I27
）
Take discharge process for example
：
●
DISC Gate Open process
：
When discharge process start
，
controller output DISC
Gate Open signal
（
O23
）
to control discharge motor turn to DISC Gate Open way, and
continue set DISC motor gate open signal output timer
，
then DISC Gate Open
（
motor
）
signal
（
O23
）
output.
●
DISC Gate close process
：
When discharge is finished
，
output DISC Gate close
signal
（
O24
）
,to control discharge motor turn to DISC Gate close way, until detect DISC
Gate Closed signal
（
I27
）
input valid then stop output DISC Gate close signal
（
O24
）
,DISC
gate is in close state.
※
Note
：
If DISC Gate close process time exceed set DISC Gate close overtime timer
，
controller still undetect DISC Gate Closed signal
（
I27
）
,then controller will stop
output DISC Gate close signal
（
O24
）
and alarm. After Clear Alarm
，
will continue
output gate close signal.
