Enable/Disable Ejectors
(EPC03)
- BIT 09 controls whether the QDC module performs any profiled
ejector movement. The QDC module:
0 = Executes profiled ejector movement
1 = Inhibits any profiled ejector movement
We recorded zero to enable ejector movement on Worksheet 8-F.
Logical Bridge
(EPC03)
- BIT 08 controls how the QDC module starts the ejector profile:
0 = upon clamp position during clamp open profiles
1 = on command from the PLC processor
We recorded a 1 to start on PLC command on Worksheet 8-F.
Profile Algorithm
(EPC03)
- BIT 00 selects which algorithm the QDC module uses for the ejector
profile.
0 = Velocity vs. position algorithm
1 = Pressure vs. position algorithm
We recorded a value of 1 for a pressure vs. position algorithm.
Important: All other bit selections in EPC03 should be zero.
Expert Response Compensation
(EPC04
)
- BITs 09 and 08 determine whether you apply Expert Response
Compensation (ERC) to ejector profiles. ERC is an exclusive
algorithm that adjusts for changes in your machine, hydraulics, raw
materials, and other process variables. It compensates for abrupt
upsets and long term deviations.
0 = Expert Response Compensation ON
1 = Expert Response Compensation OFF
We recorded a value of 1 (ERC = Off) on Worksheet 8-F.
