8.4.1.2 Feed constant
The feed constant corresponds to the movement of the machine during one revolution of the
gearbox output shaft.
• The entry in the Feed constant ( C01204 ) field is made in the user unit [units] in respect of the
revolution.
• In the case of a conveyor drive, the feed constant is obtained from the drive roll's circumference,
which, in the following example, is calculated on the basis of the indicated diameter:

• In the case of a spindle drive (linear axis), the feed constant is derived from the leadscrew pitch.
The feed constant indicates the distance the slide travels during one revolution of the spindle
(in the following example: 5.023 mm).

• In the case of a rotary table and its specification as an angle, the feed constant
is = 360°/revolution.
