4-10
which is set by the internal parameter.
Ｅ
Mold opening decompression position
：
it’s the switching position of mold opening from
low speed to high speed
，
usually this value is set same as mold clamping high pressure
mold locking position
Ｃ
. Before this position
，
only small pump is active
，
if this position is
set to 0
，
opening decompression is bypassed. This position can’t be set to 0 in normal
condition
，
always set it properly to achieve open decompression.
Ｆ
Clamp must run with low pressure and low speed in last opening step
，
this is to achieve
stable stop position
，
adjust high speed to low speed position so that the clamp open
operation can be transited smoothly from high speed to low speed before stopping.
Ｇ
MOLD PROTECTION T.
：
It must be set a little bit more than
Ｂ
→
Ｃ
actual time.
Ｈ
CLOSE MONITOR T.
：
It must be set a little bit more than
Ｂ
→
Ｄ
actual time.
Ｉ
OPEN MONITOR T.
：
It must be set a little bit more than
Ｅ
→
Ａ
actual time.
Ｊ
ROBOT SIGNAL PT./T.
：
When the mold is opened to the set position or greater than
mold open end set position
，
computer will output a signal (I/O 196) to robot interface to
trigger picking up of the finished parts. The second set point is robot signal check timer
，
robot must give a signal to allow mold close within interval time or robot signal check
time.
Case 1
：
Interval timer >= robot signal timer
：
next cycle starts when interval timer expired
and robot enable mold close signal is on
，
otherwise alarm no.36 is fired.
Case 2
：
Interval timer < robot signal timer
：
next cycle starts when robot enable mold close
signal is on before robot signal timer expired
，
otherwise alarm no.36 is fired.
Set interval timer = 0 and appropriate robot signal timer
，
this will initiate next cycle start
once robot enable mold close signal is on.
Ｋ
It must be set ON if machine runs with robot.
◇
The position of clamp close from low pressure to high pressure position is
the male and female mold halves are just contacted +3.0~5.0.
CAUTION
◇
The position of clamp open low speed to high speed position is the male
and female mold halves are just touched (clamp release position)
－
5.0~10.0.
