6.2.11.0 Considerations for Profile Design
You can create a profile using one of the following tools:
• A text editor
• A spreadsheet application
When creating profiles, be aware of:
• The selected resources
The Station Manager application and the MPE application must be opened with a configuration file that
is compatible with the profile file.
• The selected dimension
With standard engineering dimensions, you need to ensure that one of the profile file dimensions matches
one of the control mode dimensions available in the station configuration.
With normalized dimensions, you can select any of the control modes available in the station configuration.
6.2.11.1.0 Profile Types
The Profile activity supports block-arbitrary profiles and phase profiles.
Block-arbitrary profiles
A block-arbitrary profile defines a particular command segment (or a series of segments) for each channel.
Each segment can have a different shape, rate, repeat count, and amplitude.
A block-arbitrary profile can define several channels of data since there is no interaction between the data
channels.
Phase profiles
A phase profile also defines a particular command segment (or a series of segments) for each channel.
However, the segment shape, time base, and count must be the same for each channel.
A phase profile can define several channels of data. Each row of segment data can have phase lag defined
for it. The phase lag of each channel is referenced to the lowest Phase Lag defined in a channel.
6.2.11.2.0 Using ALC with the Profile Activity
ALC (arbitrary end-level compensation) is an adaptive compensation technique that improves the tracking
accuracy of MPE. ALC compensates for peak and valley errors by building (and continually updating) a matrix
of amplitude compensation factors.
ALC compensator settings
ALC compensator settings are enabled only if ALC has been selected as the compensator.
