Feed constant

Information indicating how many units are traversed with a revolution at the

gear-output end (e.g. 360°, 500 mm, …).

• The same applies if you have several panels on a tool within this revolution.

Resolution

Resolution of an encoder revolution (shift factor)

• Higher values usually lead to greater positioning accuracy and a higher

dynamic performance but limit the traversing range that can be shown.

• If possible, consult Lenze if you want to use a resolution different to the

default setting.

Gearbox numerator/

denominator

The gearbox ratio is to be stipulated in the form of two gearbox factors

(numerator/denominator) and indicates the number of motor-axis revolutions

during which exactly one revolution around the load axis (e.g. spindle or drive

roll) takes place.

• You can obtain the necessary data from the Technical Data of the gearbox.

For exact stipulation of the gearbox ratio, you should use the resulting teeth

numbers indicated on the data sheet or in the catalogue instead of the

information on the nameplate.

Reference speed

Indication of maximum speed at which the axis is traversed.

• All acceleration and deceleration ramps, among other things, of the FBs that

use this measuring system make reference to this value.

Load moment of inertia

This optional information is used to calculate the precontrol variables and

usually leads to a better dynamic performance and a greater precision.

Motor moment of inertia
Minimum / maximum

Specification of the unlimited/limited traversing range

• Example 1:

0,0000 mm (minimum) to 500,0000 mm (maximum) in the "Unlimited"

traversing range.

• Example 2:

-10,0000 mm (minimum) to -100,0000 mm (maximum) in the "Limited"

traversing range.

PLEASE NOTE: Changes in the Minimum and Maximum input fields have an

effect on the worksheet in the »Cam editor«. By this, motion profiles, cams, or

position marks already entered may be deleted.

Cycle

Specification of the cycle for the "Modulo" traversing range.

• Example: Cycle 180,0000° for a double use.

PLEASE NOTE: Changes in the Cycle input field have an effect on the worksheet

in the »Cam editor«. By this, motion profiles, cams, or position marks already

entered may be deleted.
