Maximum RPM Control Limit
(PLC46)
The value in this word corresponds to the maximum controllable RPM
during the plastication profile. The QDC module uses this word with the
Selected RPM Valve, Output for Maximum (word 48) below. The QDC
module expects this RPM when setting the selected RPM valve to the
percentage output you enter in word 48.
Record the maximum screw RPM per your OEM specifications on
Worksheet 7-D.
Selected RPM Valve, Output for Minimum
(PLC47)
The QDC module uses this word with the Minimum RPM Control Limit
(word 45) above. Enter the %-signal output that the QDC module uses to
drive the selected RPM valve for minimum profile RPM. The QDC
module expects an RPM equal to word 45 when setting the selected RPM
valve to this percentage output.
Determine Output for Minimum values as follows:
0 (0%) for uni-directional direct acting valves
5000 (50%) for bi-directional valves
9999 (100%) for uni-directional reverse acting valves
If your selected
pressure valve is:
Then the value in word 47
should be:
And during the profile, the QDC
module does NOT drive the valve
with a % output:
Direct Acting
less than the value in word 48
less than the value in word 47
Reverse Acting
greater than the value in word 48 greater than the value in word 47
Record your initial Output for Minimum value on worksheet 7-D.
Selected RPM Valve, Output for Maximum
(PLC48)
The QDC module uses this word with the Maximum RPM Control Limit
(word 48) above. Enter the %-signal output that the QDC module uses to
drive the selected RPM valve for maximum profile RPM. The QDC
expects an RPM equal to word 46 when setting the selected RPM valve to
this percentage output.
