The following sections describe how to complete Worksheet 8-B. After
each section is discussed, fill in values for the mentioned words or bits.
Clamp Open Profile Block Identifier (OPC01)
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 open profile. These first eight bits
must be set at 00010101.
Clamp Open General Definition (OPC03)
The following BITs of OPC03 determines how you define clamp open
profiles and how they are executed. All other bits of OPC03 should
remain zero.
- BIT 15 selects when the open dwell timer starts. The state of this bit
informs the QDC module when to start its internal mold open dwell
timer.
0 = starts dwell timer when OSC is complete
1 = starts dwell timer when ejector profile is complete and mold
is open
- BIT 14 selects how velocity setpoint values for the clamp open
operation are interpreted by the QDC module.
0 = Percent Velocity
1 = Inches or Millimeters per second
At this time, select 1 for bit 14.
- BIT 11 controls the QDC module’s reaction if the profile
configuration forces the QDC module to move the clamp into the
Open Slow Zone while executing 1st or 2nd or 3rd clamp open.
0 = Start executing open slow if zone overrun occurs
1 = Stop and zero outputs if zone overrun occurs
At this time, select 0 for bit 11.
- BITs 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 open, BIT 09 configures second clamp open, and BIT 08
configures first clamp open. 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
At this time, select 0 for bits 10, 09, and 08.
- BITs 06, 04, 02, and 00 select which algorithm is utilized by the
QDC module for each profile. BIT 06 configures open slow, BIT 04
configures third clamp open, BIT 02 configures second clamp open,
and BIT 00 configures first clamp open.
0 = Velocity vs Position algorithm
1 = Pressure vs Position algorithm
At this time, select 1 for bits 06, 04, 02, and 00.
