Motor/encoder feed constant
The feed constant corresponds to the machine motion for one revolution of the gearbox out-
put shaft.
When a turntable is used, the feed constant is = 360°/revolution when defined as an angle.
The feed constant of a conveyor drive results from the circumference of the drive roll.

Example:
The feed constant of a spindle drive (linear axis) results from the leadscrew pitch. The feed
constant indicates the distance travelled by the slide in one revolution (in the following exam-
ple 5,023 mm).

The kinematic parameters for the second encoder can be used to define how an imported
encoder position or encoder speed should be converted into machine units.
