Introduction

• The DDCS V4.1 4 axes motion controller for stepper and servo system, is updated from DDCS V3.1 on software and hardware. It combines great advancement with tiny footprint of each days from past 8 years. The DDCS numerical control system adopts the ARM + FPGA design framework. ARM controls the human-computer interface and G-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 V4.1 is very rational to save space. All operations are controlled by only 17 keys and the keys are composite keys that can act as function keys or numeric keys. DDCS V4.1 support comprehensive Fanuc G code set. The DDCS can be used for many styles and types of CNC machines. Lathes, Routers, Pick&Place and Mills are just a few examples. The DDCS operates as a Stand Alone system without the need of a computer. This guarantees high precision, accuracy and reliability. The interface, even though very comprehensive, can be learned in a very short time.

DDCS V4.1 Stepper/Servo Control Output

The stepper/servo control output,we cite differential Pulse and Direction output method.By the Para #012~015, the users can configurate the drive mode for the 4 axis. Max. output frequency is 500Khz, please take attention to the max. pluse input frequency of the driver.

Limit, Home and Probe Inputs

The digital input circuit has the mechanical limit switch connection method and the open collector of the triode connection method. It supports the NPN type proximity limit switch. The example above, we already set at Submenu “Input signal Para” in the Parameters page as: #151: X axis Home port is 03, then IN03 is the X axir home signal input port； #152: Y axis Home port is 06, then IN06 is the Y axir home signal input port； #153: Z axis Home port is 09, then IN09 is the Y axir home signal input port. #156: Probe Port is 13, then IN13 is the probe signal input port.

Extended Function Inputs

#250~#253 Extended function key functions: 0 "Start"; 1 "Pause"; 2 "XY Zero"; 3 "Z Zero"; 4 "Home"; 5 "Floatting probe"; 6 "Fixing probe"; 7 "Vertex probe"; 8 "X 1/2"; 9 "Y 1/2; 10 "extkey1.nc"; 11 "Disable". The users can select the function as they want. Take the example, how to defind the “Start”, “Pause” and “E-stop”Extended function to the external keys. By Submenu “Input signal Parameters” in the Parameters page: Set “#157 External emergency stop port” to No. 16 input port; Set “#158 Extended Function Key 1 Port” to No. 14 input port; “#159 Extended Function Key 1 Port” to No. 15 input port. Then set #250 to 0, then define input port 14 as “Start”; Set # 251 to 1, to defind the input port 15 as the "Pause". The users also can edit Macro to self-define the external key function by “extkey.nc“. The appendix also includes a list of macro definitions.

DDCS V4.1 Spindle control outputs

• DDCS V4.1 Support 2 kinds Spindle Mode: Analog Spindle / Servo Spindle (PUL+DIR). By Para #188 configurate the spindle as Analog or Servo Spindle, By Para #189 we select the servo spindle channel. Here we take the example of the analog spindle.
• The spindle control output ports （OUT01-OUT03） offer connections for Start and Stop of the Spindle (M3/M5), Start/Stop of Cooling (M8/M9), Start/Stop of Lubrication (M10/M11). These three output terminals are signals open to ground. The highest electric current can be absorbed is 50mA. The speed controlling output terminal can output 0-10V. It can adjust the speed of the spindle motor by sending the voltage between 0 and 10V to the VFD according the the Spindle Speed Setting.
• The above Figure shows the wiring with Sunfar VFD.

1） The internal of the analog circuit is isolated from the IO power supply, and it is forbidden to short-circuit with IO power supply.

2) M3 is the spindle forward rotation output or start-stop output;

3) If the IO port is not powered, even if the inverter is connected correctly, it will not work; all IO ports must be powered to work properly.

When the spindle mode is Servo spindle, we need to choose the servo spindle channel, and wire with according driver ports to the spindle servo driver.

Needs two power supplies

• COM+ and COM- is the power input ports for Input/Output Port and MPG， 24V and GND is the power input ports for controller system. Please keep in mind,only when the two power supplies are connected correctly the controller can be work properly.
• The DDCS V4.1 is a small box that can fit in a window of a small control box or control cabinet.
• Four locking hooks fix this controller from the frame. The dimension you find in Figure 1-3.
• The front panel is 237mm * 153.7mm * 5.2mm；
• The main body is 237mm * 153.7mm * 48.2mm；
• To mount the unit in an equipment cabinet, cut the hole 228.5mm * 83.7mm
