Introduction:

- The DDCSV2.1 is the 3 axis and 3 axis motion controller which has been researched and developed by Faster CNC for four years.The control period of each position is only 4 milliseconds,with a high control precision.The highest uniaxial output pulse is 500KHz and the pulse width can be adjusted.It supports the common stepper motor and servo motor.
- The DDCSV2.1 numerical control system adopts the ARM+FPGA design framework.The ARM can finish the part of human-computer interface and code analysis and the FPGA can finish the part of underlying algorithm and control pulse generate,with the reasonable design,reliable control and easy operation.
- The panel layout structure of DDCSV2.1 is rational. The common off-line operation can be finished only by 17 keys and it supports the FANUC with high universality to be compatible with G code set.
- This specification introduces the operation method of caving machine's special off-line CNC system,DDCSV2.1 and the machine tool connection as well as operation specification.By lots of graphical representation and examples,the uses can quickly learn to use the DDCSV2.1 CNC system.

DDCSV2.1 has made the following changes on the basis of DDCSV1:
1:The input signal is modified to support the NPN switch;
2:Support limit and the home share the input port;
3:Use the more stable FLASH,to ensure that no program loss;
4:Upgrade algorithm,support soft interpolation, modified V1.1 version of arc interpolation bug;
5:Upgrade the power module,the system is more stable.

- Support the panel key with single-axis manual operation,manual step and CONT operation;
- Support the operation of quickly specify the running position;
- Support the multi coordinate systems (with automatically saving function in case of power cut);
- Support the function of saving data automatically after power down (press the start to automatically save the data in the operation, automatically save the data after power down)

Outward Appearance, Structure and Size of Product:
- The DDCSV2.1 adopts the embedded shell structure,which can punch a square hole on the equipment cabinet and then embed this equipment in the squire hole. Use two locking mechanism from the inside can fix this equipment on the equipment cabinet,with easy installation.The dimension figure of the product's outward appearance are as picture 1-1 and picture 1-2.
- The panel size of the product is 163*102*5mm;The size of main body is 156mm*93mm*45mm；
- The size of square hole installed on the equipment cabinet is 156*93mm.

NVMPG-3D CNC Manual Pulse Generator MPG Coordinates Display Handwheel Open Wire

Description:
- Manual Pulse Generator named NVMPG-3D. This MPG has a screen,and 10 buttons. The coordinates and some other parameter are displayed on the screen.
- And user can change axis and rate by the buttons. There are also few other functions e.g. ZERO/ GOTO0/HOME on the buttons.
- The encoder of NVMPG is the same as general MPG. but the choice of axis and rate use USART port instead of general port.
- There are 2 mode of terminal: open wire and RJ45 port.  This is the open wire version. ( RJ45 port )

Specifications:
- Version: open wire
- High performance
- 2.2" TFT Screen
- 10 buttons
- Voltage 5VDC
- 8 wire control line
- 6 axis coordinates /RESET/FRO/SRO/SJR/SPINDLE are display on the screen

Connection interface definition:
NVMPG-3D has 8 wires connected to CNC system, the definition of NVMPG

Package List:

- 1 x 3-Axis CNC Motion controller
- 1 x  NVMPG-3D Manual Pulse Generator
