Set the Base Update Period
The Base Update Period is basically the RPI rate for Ethernet communication
between the controller and the motion module, a Unicast connection. It also
sets the motor feedback that is returned from the drive in the drive-to-
controller connection.
There are two alternate update periods that you can configure when using Axis
Scheduling. See Axis Scheduling on page 145
for details.
The Base Update Period is how often the motion planner runs. When the
motion planner runs, it interrupts most other tasks regardless of their priority.
The motion planner is the part of the controller that takes care of position and
velocity information for the axes.
