Combined Follower and Commanded Motion

Combined motion consists of Follower motion commanded from a master axis combined with one

of these internally commanded motions:

Jog Plus/Minus %Q Command

Move at Velocity %AQ Command

Move %AQ Command

Stored Motion Program

Combined motions are additive. The slave axis motion is equal to the sum of the motion

commanded by the master axis and the internally commanded motion.

Example 1: Follower Motion Combined with Jog

In this example, the Enable Follower %Q bit is set, causing the slave axis to follow the master

input. While the slave axis is following, the Jog Plus %Q bit is set. The following axis

accelerates from its master’s velocity to its master’s velocity added to the current Jog Velocity.

This acceleration will be just as if the axis was not following a master source at the time. When

the Jog Plus %Q bit is cleared, the following axis decelerates to its master’s velocity. In the

velocity profiles below, the dotted lines indicate when the Jog Plus %Q bit is turned ON and then

OFF.
