1 DDCS V2.1 Controller Introduction

1.1 Introduction of Product

Digital Dream has a 20 years history in the numerical control industry, specializing in the research, devel-
opment and production of various CNC (Computer Numerical Control) systems. Digtital Dream aims to
combine high quality and high reliability with affordability. We produce 1 axis to 6 axes CNC system.
The DDCS V2.1 is a 4 axis motion controller for stepper and servo systems. We are very proud of this
product, it combines great power with a tiny footprint and is easy to use. After a very short time you will be
familiar with the functions and this manual will help you. The highest output pulse per axis is 500KHz. The
pulse width is adjustable (refer to driver manual). The control period of each position is only 4 milliseconds.
This provides high control precision for stepper motors and servo motors.
The DDCS V2.1 numerical control system adopts the ARM+FPGA design framework. ARM controls the
human-computer interface and code analysis and the FPGA provides the underlying algorithms and creates the
control pulse. This guarantees reliable control and easy operation. The internal operating system is Linux based.
The panel layout structure of the DDCS V2.1 is very rational to save space. All operations are controlled
by only 17 keys and a comprehensive G code set is supported.
The DDCS V2.1 can be used for many styles and types of CNC machines. Lathes, Routers, Pick&Place and
Mills are just a few examples. The DDCS V2.1 operates as a Stand Alone system without the need of a comput-
er. This guarantees high precision, accuracy and reliability. The interface, even very comprehensive, can be
learned in a very short time.
