Inertia
The property of an object to resist changes in rotary velocity unless acted upon by an outside force. Higher inertia objects
require larger torque to accelerate and decelerate. Inertia is dependent upon the mass and shape of the object.
Input Function
See destination. A function (i.e., Stop, Preset) that may be assigned to an input line. In PowerTools Pro, the input function
is connected to the action through click and drag operations in PowerTools Software on the Assignment View.
