inverting The polarity of a switch (limit switch, home switch, and so on) in active
state. If these switches are active low they are said to have inverting
polarity.

limit switch/
end-of-travel
position (input) Sensors that alert the control electronics that physical end of travel is being
approached and that the motion should stop.

MCS move complete status
microstep The proportional control of energy in the coils of a stepper motor that
allow the motor to move to or stop at locations other than the fixed
magnetic/mechanical pole positions determined by the motor
specifications. This capability facilitates the subdivision of full mechanical
steps on a stepper motor into finer microstep locations that greatly smooth
motor running operation and increase the resolution or number of discrete
positions that a stepper motor can attain in each revolution.
modulo position Treat the position as within the range of total quadrature counts per
revolution for an axis.
