14.1 Functions
AH20MC-5A is equipped with a DMCNET port. A DMCNET is Delta motion control communication. It
is a real-time system. It only takes 1 millisecond to update the commands sent to the twelve axes in
AH20MC-5A. There are several modes of returning home. The twelve axes in AH20MC-5A can
move synchronously. They are divided into four groups so that three-axis helical/linear interpolation
can be used. They are divided into six groups so that two-axis linear/circular interpolation can be
used.

A DMCNET supports twelve Delta ASDA-A2-F AC servo drives.

Users can write the values of parameters into a servo drive and read the values of parameters
from the servo drive by means of a DMCNET.

User can instruct an axis to return home by means of a DMCNET, and axes can move
synchronously by means of a DMCNET.
