NTA FANUC Test 2 – Teach Pendant, Alarms, Jogging and Initial Setup Practice Test

The question is about what can and cannot limit how far the robot axes can move. The moving range is defined by physical and safety boundaries, plus how you’ve programmed the robot to avoid collisions. Work area limitations set the overall envelope in which the robot is allowed to operate, so they directly constrain reach. Tooling and fixture interference points are physical obstacles; if a tool or fixture would collide with the arm, you must keep the motion within a safer, smaller range to prevent contact. Cable and hose length also imposes a real, mechanical limit: as the arm extends, tethering can wrap or snag, so the usable range is reduced to avoid such issues.

Power supply voltage, by contrast, affects how quickly and forcefully the robot can move—its speed, torque, and acceleration—but it does not inherently change the geometric reach of the axes. If the voltage is adequate, the robot can reach its full range; if it’s insufficient, performance may degrade, but the fundamental operating range isn’t the constraint.
