Clamp Open Slow Profile Setpoints

Word

Description

OPC36

Segment 1 Velocity Setpoint [07] or [08]
if:

then the module:

you select Vel/Pos profile execution

controls clamp open speed to this setpoint after starting the Clamp Open Slow Profile
until clamp position reaches the smaller of non-zero OPC38 or OPC62

OPC03-B14 is RESET

reads this parameter in percent velocity

OPC03-B14 is SET

reads it in in.(mm)/s

OPC37

Segment 1 Pressure Setpoint [02] If you select Press/Pos profile execution, the module controls clamp open pressure to this set-
point after starting the Clamp Open Slow Profile until clamp position reaches the smaller of non-zero OPC38 or OPC62.

OPC38

End of Segment 1 Position Setpoint [14]

OPC39

Segment 2 Velocity Setpoint [07] or [08]
if:

then the module:

you select Vel/Pos profile execution

controls clamp open speed to this setpoint from the clamp position OPC38 until clamp
position reaches OPC62

OPC03-B14 is RESET

reads this parameter in percent velocity

OPC03-B14 is SET

reads it in in.(mm)/s

OPC40

Segment 2 Pressure Setpoint [02] If you select Press/Pos profile execution, the module controls clamp open pressure to this set-
point from the clamp position OPC38 until clamp position reaches OPC62.

OPC41 - 60 Open

Critical Process Setpoints

Word

Description

OPC61

Start Clamp Open Slow Position Setpoint [14] The module uses this clamp position as protection against running a Clamp Open
Profile into the Open Slow Zone. If this position is reached while the module is executing any of the first three Clamp Open Profiles,
the module immediately terminates the ongoing profile and checks the state of OPC03-B11.
if this overrun Bit:

then the module:

is RESET

immediately begins the Clamp Open Slow Profile

is SET and SYS21-B14 is RESET

sets its outputs to zero

is SET and SYS21-B14 is SET

gives output control to the Ejector Profile

is less than or equal to clamp position

sets master status bit SYS03-B06

reaches the Open Slow Zone while

sets alarm status bit SYS07-B07

executing one of the first three Clamp
Open Profiles

OPC62

Mold Open Position Setpoint [14]
The module uses this clamp position as the End of Open Slow position setpoint.
if:

then the module:

this position is reached while the module

immediately terminates Clamp Open Slow Profile and

is executing the Clamp OpenSlow Profile

SYS21-B14 is RESET

sets outputs to values OSC33 - OSC40

SYS21-B14 is SET

gives output control to the Ejector Profile

clamp position equals or exceeds this entry

sets master status bit SYS03-B07

OPC63

Mold Open Dwell Timer Preset [21]
When the module starts its internal Mold Open Dwell Timer (see OPC03-B15), it:

S

sets master status bit SYS03-B09

S

reports the accumulated value of the timer in SYS59

When the Mold Open Dwell Timer accumulated value in SYS59 equals this entry, the module:

S

resets master status bit SYS03-B09

S

stops accumulating time in SYS59

If it receives an F-to-T transition of any new action execution command except DYC02-B14 (Execute Ejector Profile), the module:

S

resets master status bit SYS03-B09

S

resets SYS59 to zero
