1.6 FmXP Features
FmXP is designed for a wide range of users to simplify programming and testing of complex dispensing
routines that require explicit machine and fluid controls. Menu access is restricted by passwords, while
providing the user the flexibility needed to complete the job efficiently.
Some of the features that make FmXP a flexible and easy-to-use benchmark for dispensing system
software are briefly described below.
1.6.1 Advanced Fluid Management
1.6.1.1 Flowrate Max and Min Associated with Fluid Files
All dispensing programs have an associated fluid file, which defines the fluid characteristics. As an
option, the maximum and minimum fluid flow rate values can be saved with the fluid file. If the fluid file
is bundled with the dispensing program in a recipe, the flow rate range will be application dependent. See
5.4.1 Fluid Setup.
1.6.1.2 Low Fluid Software Solution
For systems without hardware sensors to determine a low fluid condition, FmXP can estimate the fluid
usage by tracking dispensing events (dots, lines, purging, priming, flowrate calibration, etc.). A flowrate
calibration is required to use this feature. The fluid usage will be tracked by calculating the number of
milligrams used per operation. See 5.4.1 Fluid Setup.
1.6.1.3 Multiple Flow Rates (Variable Valve Speed)
Multiple flow rates (Variable Valve Speed) can now be introduced into a dispensing program and
dispensing valves can be commanded to shift to pre-calibrated motor speeds in between dispenses. The
ability to adjust the valve speed through the software allows the programmer to achieve a target weight
while maintaining the fastest possible dispense speed for each unique line. Variable Valve Speed is
available on Nordson ASYMTEK's Millennium M-2000, Axiom X-1000, and Spectrum S-820
Dispensing Systems. See 7.9 Variable Valve Speed.
1.6.1.4 Calibrated Process Jetting (CpJ™)
With this feature, volumetric repeatability can be maintained during long production runs to improve
process capability (Cpk) when dispensing fluids with one of Nordson ASYMTEK's DispenseJets.
Dispense patterns are programmed with a specified weight. CpJ periodically samples the dispense weight
per shot, and then computes the number of shots for each pattern. With this information, CpJ optimizes
line speed based on maximum specified shot interval.
1.6.1.5 Mass Flow Calibration (MFC)
Mass Flow Calibration (MFC) is a patented feature that enables the user to specify the mass to be
dispensed as a separate parameter within the dispensing elements. This is made possible by using a high
precision scale to take flow rate measurements. FmXP features a fluid manager where the user specifies
how the flow rate is to be taken. This helps to ensure a statistically meaningful flow rate value is obtained.
MFC has two major benefits. First, it ensures the right amount of material is dispensed for each part from
the beginning to the end. Second, it reduces setup times on a daily basis by automatically compensating
for changes in viscosity or fluid delivery flow rate.
