The servomotors are self-contained distributed drives,
which means that the drive electronics is housed together
with the motor in the same casing. The motion control
software also runs independently in the servomotor; which
reduces the load on the higher-level control system.
A master system controls the servomotors. In this system
servomotors operated in a DC group are controlled by a
master system.
