DYC
Word Bit Description
DYC02 B15 Stop Command
= 0 Outputs Enabled
= 1 Outputs Disabled
When the module decodes a valid DYC having this bit SET, it halts any ongoing profile or jog movement and set its outputs to
zero. The module will not respond to any new jog or profile execution commands as long as this bit remains SET. This bit may
be latched by the end user to serve as a module Stop command, or may be momentarily asserted to force the module to
terminate an ongoing profile.
DYC03 Timer Reset Commands
B00 = 0 Normal
= 1 Reset Tonnage Watchdog Timer
A false-to-true transition of this bit forces the module to zero the accumulated value of the Tonnage Watchdog Timer in SYS57.
B01 = 0 Normal
= 1 Reset Cure Timer
A false-to-true transition of this bit forces the module to:
reset master status bit SYS03-B03, reset master status bit SYS03-B05, and reset SYS58 to zero
B02-03 RFU
Co-injection Parameters
B04 DYC03.B04 for QI(A) DYCB03.B04 for QI(B)
Start Delayed Injection
Starts delayed injection of A when the screw position of B reaches IPCB08 after both QI modules are commanded to start
injection (DYC02.B04 = 1):
0 = QI(A) starts injection regardless of the B’s screw position.
If reset before B reaches IPCB08, A starts injection immediately.
1 = QI(A) suspends its inject profile until B’s preset position is reached.
Suspended injection is indicated by SYS03:B00 (SYSB03:B00).
During suspension, IPC02:B11 and .B12 determine the status of outputs.
Important: Program permissive logic that prevents starting the injection profile with this bit set in SETUP or MANUAL mode.
B05 DYC03.B05 for QI(A) DYCB03.B05 for QI(B)
Select the Mode for Input #3:
0 (default) = screw RPM
1 = cavity pressure
You may switch the input mode dynamically when the machine is idle, never during the injection phase. You must NOT bridge
directly to plastication to use this bit. If toggled during injection, the QI module will halt operation and return error codes in
SYS61, 62. You may use time delay (MCC63) to allow for relay signal settling and disable alarms during the switch-over.
Reset Commands
B08
Power Start-up Reset Command
= 0 Normal
= 1 Reset Power Start-up Bit
A false-to-true transition of this bit forces the module to unlatch SYS01-B08.
B09
Alarm Reset Command
= 0 Normal
= 1 Reset Latched Alarms
A false-to-true transition of this bit forces the module to unlatch all bits in SYS09, SYS10, SYS11, and SYS12.
B10
Profile Status Bits Reset Command
= 0 Normal
= 1 Reset Profile Status Bits
A false-to-true transition of this bit forces the module to unlatch the 15 profile complete status bits, SYS02-B00 – B14 inclusive.
B11-15 RFU
