The "NC Feed constant" parameter

The NC Feed constant defines the traveled distance of the load per revolution of the motor shaft. With the NC Feed constant you can, for example, map the transmission ratio of a gear unit.

You can set the NC feed constant in the Drive Manager 2 in the menu "Basic settings" under "Load".

Example: Calculation for a rotary NC axis with gear unit

Given:

• A gear unit with transmission ratio i = 10 (reduction)

Result:

• NC feed constant = 360° / i = 36°
