Chapter 6: System Operation
This example describes how the system should be set up when using a 250mm stroke press and
pressing to a Target Distance of 200.00mm (2 decimal place accuracy).
1. Set all distance related parameter data fields to zero: [20: Distance Low Limit],
[21: Distance High Limit], [22: Target Distance], [23: Interference Check Distance],
[24: Press Speed Start Distance], [60: Approach Distance] and [62: Job Start
Position]
2. Set System parameters as follows:
a. Set parameter 0A [Distance Decimal Point] to 2 for two decimal place
location.
b. Set parameter 0D [Stroke Distance Limit] to the max tool stroke.
c. Set parameter 0B [Approach Distance Limit]. This value will be less than or
equal to the distance offset (Ex: offset=150mm, Approach 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 reached this distance it will reset its origin for
distance calculation from the Job Start Position to the Offset Distance value.
4. Set final distance parameters [20: Distance High Limit], [21: Distance Low Limit],
[22: Target Distance] and [24: Press Speed Start Distance] based off of the amount
of Distance Offset. This value will be the original distance from start minus the
Distance Offset value. (Ex: If the original value for the [21: Distance High Limit]
was 200mm and the Distance Offset is 150mm, the new value will be 200mm –
150mm = 50mm).
5. Set distance parameters for [23: Interference Check Distance], [60: Approach
Distance] and [62: Job Start Position].
When setting these parameters, make sure the values are less than the
Distance Offset
value. This is because these values were 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 traveled 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 maximum allowable distance
for the press operation minus the Distance Offset value cannot be more than 99.99mm.
