8-4
The following sections describe how to complete Worksheet 8-A. After
each section is discussed, fill in values for the mentioned words or bits.
Clamp Close Profile Block Identifier (CPC01)
The first eight bits of this word are used to identify it as the first word in a
series of words used to define the clamp close profile. These first eight
bits must be set at 00000111.
Clamp Close General Definition (CPC03)
The following bits of CPC03 determine how you define clamp close
profiles and how they are executed. All other bits of CPC03 should remain
zero.
- BIT 14 selects how velocity setpoint values for the clamp close
operation are interpreted by the QDC module.
0 = Percent Velocity
1 = Inches or Millimeters per second
Select 1 for bit 14.
- BIT 11 controls the QDC modules reaction if the profile
configuration forces the QDC module to move the clamp into the
Mold Protection Zone while executing 1st or 2nd or 3rd clamp close.
0 = Start executing low pressure close if zone overrun occurs.
1 = Stop and zero outputs if zone overrun occurs.
Select 0 for bit 11.
- BIT 10, 09, and 08 control the logical bridge (the action the QDC
module takes when it has completed a profile). BIT 10 configures
third clamp close, BIT 09 configures second clamp close, and BIT 08
configures first clamp close. Set these bits when it is necessary to
perform some external operation between two profiles.
0 = Start next Profile when this profile is complete
1 = Stop and set-output to end-of profile values when this profile
is complete
Select 0 for bits 10, 09, and 08.
- BIT 04, 02, and 00 select which algorithm is utilized by the QDC
module for each profile. BIT 04 configures third clamp close, BIT
02 configures second clamp close, and BIT 00 configures first clamp
close.
0 = Velocity vs. Position algorithm
1 = Pressure vs. Position algorithm
Select 1 for bits 04, 02, and 00.
