Expert Response Compensation (ERC) Percentage
Word Description
ERC05 Minimum Velocity-retract Control ERC Percentage [31] Although error coding allows this entry to be within the range of 00000 to
09999, the module limits it to a minimum of 01000.
ERC06 Minimum Pressure-retract Control ERC Percentage [31] Although error coding allows this entry to be within the range of 00000 to
09999, the module limits it to a minimum of 01000.
ERC07, 08 Open
Unselected Valve Set-output Values
When the module starts an Ejector Profile retract stroke, it:
•
sets its unselected outputs to the values listed below
•
ignores the unselected value of the selected output
•
uses ramp rates ERC17 - ERC32 to ramp unselected outputs
