Configuration Selections

B00

Profile Algorithm Selection
= 0 Vel/Pos selected for Ejector Profile
= 1 Press/Pos selected for Ejector Profile

B01-B07

Open

B08

Ejector Profile Logical Bridge Selection
= 0 Start Ejector Profile on Position during Open
= 1 Start Ejector Profile on Command

if:

then the module:

EPC03-B09 = 0 and the clamp position equals or
exceeds EPC61 during any of the four Clamp Open
Profiles or while it is holding its outputs to any of the four
sets of End of Open Profile Set-output values
(FOC33 - FOC40, SOC33 - SOC40,
TOC33 -TOC40, or OSC33 - OSC40)

checks this bit

RESET

immediately begins the Ejector Profile concurrently with
any executing Clamp Open Profiles

B09

= 0 Ejector Profile Enabled
= 1 Ejector Profile Disabled

if:

then the module:

RESET and one of the following is true:

EPC03-B08 = 0 and the

clamp position equals or

exceeds EPC61 during the four Clamp Open Profiles

EPC03-B08 = 0 and the

clamp position equals or

exceeds EPC61 while module is holding its outputs
to any of the four sets of End of Open Profile
Set-output values (FOC33 - FOC40, SOC33 - SOC40,
TOC33 - TOC40, or OSC33 - OSC40)

EPC03-B08 = 1 and module decodes a valid
Dynamic Block with DYC02-B14 = 1

immediately begins execution of the Ejector Profile

SET

does not execute the Ejector Profile

B12

Ejector Profile Stop-and-Notify Selection
= 0 Ejector Profile to run without interruption.
= 1 Module to stop and notify the PLC processor at End of Stroke
if:

then the module:

RESET

executes the entire Ejector Profile when commanded, never sets master status bit SYS03-B08,
nor responds to DYC03-B15

SET

stops to notify the PLC processor when it completes advance stroke by setting its outputs to
EAC33 - EAC40, retract stroke by setting its outputs to ERC33 - ERC40, and sets master status
bit SYS03-B08

paused during the

may respond to DYC03-B15 to continue execution
