Function
Set / change the absolute
position value of the SSI encoder
Reset the current counter value
(CurCnt)
Reset the current counter value
and the assigned Y output points
from DHCCMP and DHCCMPT
instructions.
Preset the current counter value
(CurCnt)
Preset the current counter value
and clear the assigned Y output
points from DHCCMP
DHCCMPT instructions.
the encoder counter value + the value in Value.
Note:
1. Range of the value in Value: -2
Length-1)
. If the value is set out of the range, it is invalid.
2. If you are using SSI (serial synchronous interface) encoder
and the setting of counter type is Ring Counter, the Action
mode here is invalid.
3. After downloading the HWCONFIG settings, the offset value
is cleared to 0.
When the setting of counter mode is in Absolute Position, the
counter value of the SSI encoder will be offset and stored in Value.
If you set the offset value in Value, the current counter value
(CurCnt) is the value in Value. (CurCnt＝Value)
Note:
Range of the value in Value: 0 ≦ Value<2
1.
value is set out of the range, it is invalid.
2. If you are using SSI (serial synchronous interface) encoder
and the setting of counter type is Ring Counter, the Action
mode here is invalid. You can use Action=1 to change the
setting value.
3. After downloading the HWCONFIG settings, the offset value
is cleared to 0.
1. Clear the value in CurCnt to 0.
2. Clear the value in CurNo from DHCCMPT instruction.
3. Clear the flags of Match1 and Match2 from DHCCMPT
instruction.
Note: If you are using SSI (serial synchronous interface) encoder
and the setting of counter mode is in Absolute Position, the value
in CurCnt can NOT be cleared to 0 but the value in CurNo, flags
of Match1 and Match2 from DHCCMP instruction can be cleared.
1. Clear the value in CurCnt to 0.
2. Clear the value in CurNo from DHCCMPT instruction.
3. Clear the flags of Match1 and Match2 from DHCCMPT
instruction.
4. Clear the assigned Y output points (ONOFF) from
DHCCMP and DHCCMPT instructions.
1. Set the value in CurCnt as the value in Value.
2. Clear the value in CurNo from DHCCMPT instruction.
After preset, the DHCCMPT instruction performs the
comparison from the top. If the first value is bigger than the
first value to be compared in the table, the comparison stops.
If this happens, you can use the Update flag (ON) from the
DHCCMPT instruction to perform comparison again.
3. Clear the flags of Match1 and Match2 from DHCCMPT
instruction.
Note: If you are using SSI (serial synchronous interface) encoder
and the setting of counter mode is in Absolute Position, the value
in CurCnt can NOT be changed but the value in CurNo, flags of
Match1 and Match2 from DHCCMP instruction can be cleared.
1. Set the value in CurCnt as the value in Value.
2. Clear the value in CurNo from DHCCMPT instruction.
