¾ Data Number 62 - Return Position
ƒ The press will go back to this position after operating.
If a Return Operation is set and the Start signal goes low (OFF), the press
will move to this position.
¾ Data Number 63 - Δ f
ƒ It sets the load value for detecting force drop when the operation method is [Load
Yielding Point] or [Load Yielding Point Stop].
A setting is possible from 0 to 105% full-scale value.
If 1 KN is set, it detects the 1KN force drop of the previous peak value.
¾ Data Number 64 - Distance Offset
ƒ It operates with offset value calculated for each set value [20: Distance Low],
[21: Distance High], [22: Standard Distance], [24: Crossover Distance].
The data result is the value, which is offset value subtracted from absolute value.
[23: 1 ST Distance], [60: Free Run Distance], [62: Return Position] is
effected. However, input the stroke distance limit value and free run
distance limit. If it is not input (if the setting is 0), it will be object of
distance offset.
If distance offset is set to 0, it will be displayed with the set distance
decimal position.
Example of using distance off set
This will describe the case that you want to display the distance decimal point position with 2
figures, but you also want to operate the standard distance of 200mm with a 250mm stroke tool.
1. Set all parameters with distance related data to 0 (D-#20, 21, 22, 23, 24, 60, 62
and 64).
2. In the system parameter screen:
a. Set parameter 0A to 2 for two decimal place location.
b. Set parameter 0D to the max tool stroke along with load recovery decimal
point (Ex: 250mm stroke input 2500).
c. Set parameter 0B for freerun distance limit along with load cell setting (Ex:
150mm freerun distance input 1500. This value will be less than or equal to
the distance offset (Ex: offset=150mm, freerun distance must be <=150mm)
**See Warning below**
3. Input a parameter value for Distance Offset. This distance will be used to define
the second origin for distance calculations. This means that if the Distance Offset
is set to 150mm, once the press has achieved this distance it will reset its origin for
distance calculation from the start point to the offset distance value.
4. Set final distance parameters D-#20, 21, 22 and 24 based off of the amount of
Distance Offset . This value will be the original distance from start minus the
Distance Offset value. (Ex: for D-#21, if the Max Distance value was 200mm and
the Distance Offset is 150mm, the new value will be 200mm – 150mm = 50mm).
5. Set distance parameters for D-#23, 60 and 62.
When setting these parameters, make sure the values are less than the
Distance Offset
value. This is because these values are based off of the
original origin. When the press reaches the Distance Offset value, the
origin for distance calculations will change to this location. If 0D or 0B
are not set, then they will be based off of the Distance Offset value.
Note:
- If total distance is less than 99.99mm, then parameter 0A is the only change that must be
made.
- In order to obtain 2 position resolution using this setup, the Max allowable distance for the
press minus the Distance Offset value cannot be more than 99.99mm.
