8-32
Clamp Open Profile Block Identifier
(OPC01)
Bits 07-00 of this word identify it as the first word in a series used to
define the clamp open profile. These bits must be set to 00010101.
We entered these bits on Worksheet 8-E.
Velocity Units
(OPC03
)
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-E.
Zone Overrun
(OPC03)
The following bit controls the QDC modules reaction if it moves the clamp
into the open-slow zone while executing 1st or 2nd or 3rd clamp open.
- BIT 11 determines the QDC modules response to zone overrun.
0 = Start executing open slow if zone overrun occurs
1 = Stop and zero outputs if zone overrun occurs
We set this bit to 0 for start executing open slow on Worksheet 8-E.
Logical Bridges
(OPC03)
Logical bridges control the action taken by the QDC module when it
completes a profile.
- BIT 10 controls action at end of third clamp open
- BIT 09 controls action at end of second clamp open
- BIT 08 controls action at end of on first clamp open
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-E.
