Acceleration Ramp Rates
(INC1720, PKC1720, HDC1720, and PLC1720 )
The QDC module uses acceleration ramp rates when moving its outputs to
a higher setpoint during execution of a profile. They affect both selected
and unselected valves. A ramp rate of zero disables ramping, and the QDC
module steps directly from setpoint to setpoint.
We recorded zero on corresponding worksheets.
Deceleration Ramp Rates
(INC2528, PKC2528, HDC2528, and PLC2528)
The QDC module uses deceleration ramp rates when moving its outputs to
a lower setpoint during execution of a profile. They affect selected and
unselected valves alike. A ramp rate of zero disables ramping, and the
QDC module steps directly from setpoint to setpoint.
We recorded zero on corresponding worksheets.
Important: The valve spanning procedures in chapter 9 require zero
acceleration and deceleration ramp rates. We help you select the correct
final values required by your application in chapter 10. For additional
information, refer to section 3 of the Plastic Molding Module Reference
Manual (publication 1771-6.5.88).
EndofProfile Setoutput Values
(HDC3336 and PLC3336)
The QDC module sets its outputs to these values every time it completes
the appropriate profile when commanded NOT to “bridge” to the next
profile or movement. Set-outputs remain in effect until the QDC module is
commanded to start the next programmed profile (or movement) or is
stopped using stop command DYC02-B15.
Record values that correspond to zero pressure or zero flow on worksheets.
For assistance in determining your set-output values, refer to Table 7-A.
Important: The valve spanning procedures in chapter 9 require no flow or
pressure after profile execution. We help you select the correct final values
required by your application in chapter 10. For additional information,
refer to section 3 of the Plastic Molding Module Reference Manual
(publication 1771-6.5.88).
