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.
