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
