1) Click the ‘Settings’ button on the motor GUI, and select the ‘Encoder’ tab.

The lower collection of settings on this panel relate to encoder position functionality  (see Section 6.2.2. for details on the

upper collection of settings)..

Fig. 6.4   Motor settings - Encoder tab

There are two encoder positioning correction modes as described previously. The following parameters are used to adjust the

operation of these correction modes. 

Consider the following diagram that illustrates the role of each parameter:
