Clamp Close Profile Block Identifier
(CPC01)
Bits 07-00 of this word identify it as the first word in a series used to
define the clamp close profile. These bits must be set to 00000111.
We entered these bits on Worksheet 8-A.
Velocity Units
(CPC03)
The following bit determines units of measure for velocity values.
- BIT 14 selects units of measure.
0 = Percent velocity
1 = Inches or millimeters per second
We set this bit to 1 for units per second on Worksheet 8-A.
Mold Protection
(CPC03)
The following bit controls the QDC module’s reaction if it moves the
clamp into the mold protection zone while executing 1st or 2nd or 3rd
clamp close.
- BIT 11 determines the QDC modules response to zone overrun.
0 = Start executing low pressure close if zone overrun occurs
1 = Stop and zero outputs if zone overrun occurs
We set this bit to 0 for start executing LPC on Worksheet 8-A.
Logical Bridges
(CPC03)
Logical bridges control the action taken by the QDC module when it
completes a profile.
- BIT 10 controls action at end of third clamp close.
- BIT 09 controls action at end of second clamp close.
- BIT 08 controls action at end of first clamp close.
0 = Start next profile when this profile is complete
1 = Stop and set output when this profile is complete
We set these bits to 0 for start next profile on Worksheet 8-A.
