Software travel limits can be used to limit machine travel. They are often setup inside the
hardware travel limits to add a level of protection from exceeding the machines travel limits.
The SoftwareTravelLimitMinusActive source (output function) is active when the
SoftwareTravelLimitMinusPosn is reached or exceeded. Motion is halted using the
TravelLimitDecel whenever a hardware or software travel limit is hit or exceeded. Software
