Slave Group Parameter: MasterOffset

Description

This parameter is used to define the master offset value for the specified slave axis.

Each slave axis can have a unique offset applied to the master position. This is helpful when you want to use a single CamProfile for multiple followers, but each follower's cam shape is rotated some amount with respect to another follower's cam.

NOTE: The MasterOffset may be changed while following is on, but be careful to avoid undesirable motion. Large changes should be blended in as a series of small increments to avoid rapid, immediate changes in the follower position.

Associated Functions

The associated functions of this parameter are:

GetMasterOffset which sends a read request to the actual value of the master offset of the designated axis,
SetMasterOffset which sends a write request for the new value of the master offset of the designated axis.

These functions use, according to the language objects, the WRITE_CMD, READ_PARAM or WRITE_PARAM instructions.
