Span Your Valves
Chapter 9
9-8
Set New Values for the Velocity vs. Position Profile
If necessary, refer to chapter 8 for when you determine the following:
8ĆA
Velocity vs. position algorithm
IPC03ĆB01 = B00 = 0
B38/96, 97
(chapter 8)
Transition setpoints:
Time limit
Ram (screw) position
Ram (screw) pressure
Cavity pressure
Minimum position for pressure transition
IPC60 = above typical
IPC61 = estimated top of cushion
IPC62 = below mold flash pressure
IPC63 = zero to inhibit
IPC64 = zero to inhibit
N44:116
N44:117
N44:118
N44:119
N44:120
Download new values to the QDC module by downloading INC and IPC.
Important: If downloading from your programming terminal, you must
download INC first, followed by IPC (chapter 4).

Span Your Injection Velocity Valve
Span your injection valve for smooth operation at the highest desired
velocity. Do this by finding optimum values for these words:
Minimum Velocity Control Limit INC45 (N44:41)
Maximum Velocity Control Limit INC46 (N44:42)
Selected Velocity Valve, Output for Minimum INC47 (N44:43)
Selected Velocity Valve, output for maximum INC48 (N44:44)
Important: If PanelView is operational, use it to:
observe
actuals
change and download setpoints
run
profiles
Important:
We suggest that you read this entire procedure before starting.
ATTENTION: As with any machine start-up, make sure you
installed a test mold in the machine. Programming errors,
configuration errors, or hydraulic problems could lead to
machine damage or injury to personnel.
