Travel Accumulator
D Travel Accumulator (TRAVEL_ACCUM [29]) records the total change in travel, in percent (%) of ranged travel, since
the accumulator was last cleared. The value of the Travel Accumulator increments when the magnitude of the
change exceeds the Travel Accumulator Dead‐band. See figure 4‐5. You can reset the Travel Accumulator by
configuring it to zero.
D The Travel Accumulator Alert is active if the Travel Accumulator exceeds the Travel Accumulator Alert Point. The
Travel Accumulator Alert is set when the Travel Accumulator value exceeds the Travel Accumulator Alert Point. It is
cleared after you reset the Travel Accumulation to a value less than the alert point.
D Travel Accumulator Alert Point (TVL_ACCUM_ALRT_PT [84.2]) is the value of the Travel Accumulator, in percent (%)
of ranged travel, which, when exceeded, sets the Travel Accumulator Alert.
D Travel Accumulator Deadband (TVL_ACCUM_DB [84.3]) is the area around the travel reference point, in percent (%)
of ranged travel, that was established at the last increment of the accumulator. This area must be exceeded before
a change in travel can be accumulated. See figure 4‐5.
