8-1-6. Control Setup Group
1) Selection of Fuzzy Function
: Fuzzy function is an over shoot inhibitory function using the fuzzy reasoning. Fuzzy function can pro-
vide control effects in the following situations:
Starting the control when there are variation between the
desired set value and actual process value
Wanting to reduce the operative preheating period
Having severe load changes
Having frequent changes to set value
2) Selection of Time Unit
: Maximum of 99 hours 59 minutes or 99 minutes 59 seconds
can be selected in the setup item for the selection of time unit.
3) Setup of Wait Zone
: Process value must agree in accord to the process of programmed set value in program temperature
controller but unpredicted events occur. Here, if the temperature variation set in the wait zone when
moving segments, program can continue on to the next segment. However, if it is outside the
variation range, it doesn
t move on from the current segment to the next segment but rather waits
until it enters the set range of wait zone.
4) Setup of Wait Time
: When the process value doesn
t agree with the progress of the programmed set value in the
program temperature controller, in other words, when the process value is not controlled within the
range of set variation between the set value + the wait zone, program continues on when the wait
time elapses.
5) Power Recovery Motion Mode
: Can choose between COOL or HOT in the set up item. If COOL is selected, the system resets when
recovered from the power failure and if HOT is selected, it continues on from the segment operated
just before the failure.
However, must start from the beginning of the segment even if the system recovers to the
segment just operated before the power failure.
