Load Initial Configuration Values
Chapter 7
7-35
Reference the above table and enter one of the following for each Selected
Pressure Valve Maximum Output:
9999 (100%) for uni-directional direct acting valves
0 (0%) or 9999 (100%) for bi-directional valves (dependant upon
desired direction of motion)
0 (0%) for uni-directional reverse acting valves
The valve spanning procedures presented in chapter 9 require these initial
values in order to assist you in selecting the correct, final values required
by your application. Refer to Section 3 of the Plastic Molding Module
Reference Manual (pub. no. 1771-6.5.88) for more information.
As you read the following sections, fill in the values for the mentioned
words in the worksheets. Setting velocity control limits performs the same
function as setting pressure control limits.
Velocity Minimum Control Limit
(FCC45, SCC45, TCC45, FOC45, SOC45, TOC45, OSC45, EAC45, ERC45)
The value in this word corresponds to the minimum “controllable” velocity
during profile or stroke execution. This word operates in conjunction with
the selected velocity valve minimum output (word 47) below. The QDC
module expects this velocity when setting the selected velocity valve to the
percentage output defined by word 47.
Enter 0 for each Velocity Minimum Control Limit. The valve spanning
procedures presented in chapter 9 require these initial values in order to
assist you in selecting the correct, final values required by your
application. Refer to Section 3 of the Plastic Molding Module Reference
Manual (pub. no. 1771-6.5.88) for more information.
Velocity Maximum Control Limit
(FCC46, SCC46, TCC46, FOC46, SOC46, TOC46, OSC46, EAC46, ERC46)
The value in this word corresponds to the maximum “controllable”
velocity during profile or stroke execution. This word operates in
conjunction with the selected velocity valve maximum output (word 48)
below. The QDC module expects this velocity when setting the selected
velocity valve to the percentage output defined by word 48.
Enter a value for each Velocity Maximum Control Limit equal to the
maximum cylinder speed per your OEM specifications. The valve
spanning procedures presented in chapter 9 require these initial values in
order to assist you in selecting the correct, final values required by your
application. Refer to Section 3 of the Plastic Molding Module Reference
Manual (pub. no. 1771-6.5.88) for more information.
