2.4.2 Increase of the efficiency
MVX firmware V4.1 is based on a new operating system. Consequently MVX
efficiency is increased.
The main observable improvement concerns the processing times that are lower vs
preVIOus firmware versions.
Consequently a decrease of the cycle time is observed, allowing an improvement of
the monitoring rate.
2.5 Main evolutions of MVX version 3.1
Version 3.1xxx of the MVX firmware includes mainly the following new functions:
2.5.1 Compatibility with the ESA analysis by ONEPROD-
System
MVX is now compatible with the electric signal analysis (ESA) functions available in
ONEPROD NEST ANALYST (XPR).
The analysis of electric signals consists in acquiring and analysing the power supply
voltages and currents of a motor and detecting the distinctive characteristics thereof
that indicate anomalies.
Electric or mechanical anomalies on the motor can thus be evidenced (unbalance,
misalignment, broken bar, etc.).
2.5.2 Short-term memory
MVX stored in a FIFO buffer all or part of the indicators that were worked out during
the monitoring measurements.
MVX can store up to 1000 values for each indicator, with a periodicity ranging from a
few seconds (*) to 600 seconds.
This new function is available from ONEPROD NEST ANALYST (XPR) only.
