5.7 SPC/SQC
5.7.1
SPC/SQC
profile data is concentrated from memory locations (WY6)+V35 to
(WY6)+V55 of the Upload table:
V35
Profile ID
V36 – V45
V
elocity Input A
verage data
V46 – V55
Pressure Input A
verage data
NOTE:
These locations are updated at the end of a profile after it has
completely executed. If you need to retain this data for later use, you must
copy it to another location before the next profile execution completes.
All profiles collect the following types of data at the end of a profile after
execution.
NOTE:
For Overlap mode (executing Plasticate profile and Clamp Open
profile in the same machine cycle):
Because of the restriction in available
memory
, the module updates only plasticate SPC/SQC data and does not
update for Clamp Open profile.
• Profile ID. This
location identifies the type of profile collecting data:
100 = Clamp Close profile
200 = Injection profile
300 = Pack and Hold profile
400 = Plasticate profile
500 = Clamp Open profile
• Velocity Input Average. These
10 locations correspond to a profile
step data. (For example: if reporting data for a Clamp Close profile,
location 36 is the average velocity input for clamp close step 1 position
data.)
A
veraging of each location is based on a 10-sliding-window value
method. For example, if the module took 20 position readings during a
step and turned them into velocities, the average velocity will be
calculated (at the transition of the step to the next) by using only the
last 10 values. If the number of calculated velocities is less than 10, the
module uses the actual number of calculated velocities for calculating
the average.
