8-34
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. Pro-Set 600 sets these bits to 00010101.
We recorded this value 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 recorded the value of 1 for units per second on Worksheet 8-E.
Overrun Zone
(OPC03)
The following bit controls QDC module reaction if it moves the clamp into
the overrun zone while executing the 1st, 2nd, or 3rd clamp open profile.
- BIT 11 determines the QDC modules response to the overrun zone.
0 = Start executing open slow (OSC) if clamp reaches OPC61
1 = Stop and zero outputs if clamp reaches OPC61
We recorded the value of 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 recorded the value of 0 for start next profile on Worksheet 8-E.
