Setting the load parameters

1. In Drive Manager 2, open the menu item "Load" in the "Basic Settings" tab.
Setting the load parameters 1:

You can set the following parameters here:

NC Feed constant

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.

Example calculation for a rotary NC axis with transmission ratio i = 10 (reduction ratio):

Setting the load parameters 2:

Load inertia (reflected on motor side)

If you know the moment of inertia of the load, proceed as follows:

1. Enter the moment of inertia.
Tip: if you are using a gear unit, use the moment of inertia calculator:
Setting the load parameters 3:

2. Confirm the entry with [Enter].

A button appears: "Recalculate VCtrl Kp and reset Tn".

3. Click on the button "Recalculate VCtrl Kp and reset Tn".

The Drive Manager 2 calculates suitable controller parameters for the speed controller.

Mechanical torque limit on motor

This value is the upper limit for the motor shaft torque. Set the value according to the requirements of the application.
Note: If you use a gear unit, the torque at the output of the gear unit may be higher than at the motor shaft.

Mechanical speed limit on motor

This value is the upper limit for the speed of the motor shaft. Set the value according to the requirements of the application.
Note: If you use a gear unit, the speed at the output of the gear unit may be higher than at the motor shaft.

	Transfer parameters to the NC Once the parameters have been set, they must be transferred to TwinCAT NC. In this "Quick Start Guide to Commissioning", this is done in the next step "Test run" by enabling the TwinCAT configuration.
