Set New Values for the Velocity vs. Position Profile
If necessary, refer to chapter 8 for when you determine the following:
8ĆB Velocity vs. position algorithm IPC03ĆB01 = B00 = 0 B38/96, 97
Transition setpoints:
Time limit
Ram (screw) position
Ram (screw) pressure
Minimum position for pressure transition
IPC60 = above typical
IPC61 = estimated top of cushion
IPC62 = below mold flash pressure
IPC64 = zero to inhibit
N44:116
N44:117
N44:118
N44:120
Download new values to the QDC module by downloading INC and IPC.
Important: If downloading from your programming terminal, download
INC 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 for injection profiles, use it to:
observe actuals
change and download setpoints
run
profiles
Important: We suggest that you read this procedure before starting.
ATTENTION: As with any machine start-up, install a test
mold. Programming errors, configuration errors, or hydraulic
problems could lead to machine damage or injury to personnel.
ATTENTION: Be sure all machine guards and shields are in
place before proceeding.
