RosettaCNC Board A is an ETHERNET motion controller that manages up to 4 interpolated axes. The ETHERNET port (instead of USB) ensures fast and secure transmission thanks to the protocol and at the e galvanic insulation with the PC connection.
Does not require the use of external electronic parts or protectors. The power supply is integrated and protected, The inputs and outputs are equipped with opto-insulator that guarantee, together with the metal container, high resistance to electromagnetic interference. The outputs are protected from short circuits and allow you to directly connect inductive loads (relays or solenoid valves), without having to add external components.
The control outputs of STEP/DIR type are generated by a powerful FPGA That allows to reach operating frequencies of 2MHz (with stable duty cycle at 50%) making it possible to use both step-by-step drives and servo drives.
Rosetta CNC Board commands the axes using a look ahead that allows you to achieve high interpolation speeds.
The product can possibly be equipped with a handwheel, supplied already complete with connector, alternatively, it makes available inputs for the jog connection joystick type and other useful control signals.
Rosetta CNC Board is equipped with removable spring connectors to allow quick wiring, highly reliable and free to vibrations.

RosettaCNC Motion® is a system composed of the following elements:

• RosettaCNC Board A which is the motion controller described in this document.
• RosettaCNC software, a complete Windows® application to configure, monitor, and execute G codes.
• THe RosettaCNC Handwheel A accessory, a practical and economical handwheel.
• The RosettaCNC MPG A accessory, is a rotary device to change the override.

With the product ordering code it's possible to obtain exactly the features.
Check that the product features match your needs.

RosettaCNC Board it's powered in low voltage, 24VDC, the I/O line are opto-insulated and the PC connection is galvanically isolated, therefore the device is not a direct threat to the health and life of the user.
The design of a complete control system (electric panel), should draw attention to different aspects of, so that the whole machine system does not become a danger during the use.
It's good practice to always use NC contacts for the limit switches and for the emergency button So that a wiring error or a wire disconnection always lead to machine shutdown.
Special attention must be paid to the emergency stop circuit: The control system must be designed in such a way the that when you press the button for emergency stop, the machine immediately interrupts the movement of all axes. You should also consider the possibility of failure of particular components of the system, as the main controller, or the axes control units.

Here are two examples of connection. The first uses the Safe Torque Off (STO) input Present in drives.
The second uses a safety device to control the chain of emergency signals.

In the below picture, is used a safety device Pilz model PNOZ X7. The emergency button, and possibly other alarm signals (safety barriers, crankcase opening, etc.) must be connected to the input circuits. An output must be connected to the EST1 input of RosettaCNC Board And in series also the drive ok outputs. The other exit of the safety module must be used to stop power to drives.
S1 is the Restore button.
S2 is the stop button in emergency.

* Connectors CN4 and CN10 are available only with field I/O Expansion = 1 o 3, in order code.
** Connector CN14 is available only with field I/O Expansion = 2 or 3, in order code.

The digital inputs called “User input” can be configured by the RosettaCNC software to perform some functions. For example; ESTOP 1, Spindle ok speed, Spindle zero speed, Limit, Start, Safety barriers, etc.

The following connectors are used for different functionalities depending on the value of the “Controller type” parameter. This parameter is present in the “RosettaCNC card settings” panel → Jog.

Each analogue input can be configured via the RosettaCNC software to manage an override. The settings are found in the “RosettaCNC tab Settings ” Panel → “Overrides”.

The following parameters can be set:

• Jog Speed
• Fast (G0) Speed
• Feed (G1,G2,ecc) Speed
• Spindle Speed

Furthermore, only the AN1 analog input can be used to connect a Laser type digitizer. The settings are present in the panel “RosettaCNC tab settings” → “Digitizer”.

X = Irrelevant setting
Pot. = Potentiometer input type
0-10V = Voltmetric type input
0-20mA = Amperometric type input

• AI1 voltmetric
• AI2 amperometric
• AI3 potenziometric

If the analog inputs expansion is present, it is possible to connect a Panasonic HG-C1100-P Micro Laser Distance Sensor to the AI1 input.

The following operations are possible through the laser sensor:

• Surface scan for 3D model (model STL file creation and TXT file with acquired data cloud).
• Scan for surface flatness mapping (creation of surface STL files and TXT files with acquired data cloud).

To function properly the sensor must be reset to the factory settings and analogue input AI1 must be set in 0-20mA amperometric configuration.

More details on the connections and configuration of the Laser sensor refer on the application note: AN003 - Panasonic HG-C Series Laser Sensor

The digital outputs called “User Output” can be configured by the RosettaCNC software to perform some functions. For example: spindle ignition with rot. hourly, ignition spindle with rot. counter-clockwise, air activation, water activation, aux outputs 1..4, etc.

Inserting one of the JP3, JP4 o JP5 jumpers, You can choose the operating voltage of the STEP and DIR outputs.

	Name Jumper	Setting	Nominal voltage
	JP3	INSERTED	Selects the STEP/DIR signal voltage to 12V
	JP4	INSERTED	The STEP/DIR signals have a voltage equal to the value in the 1A or 1B terminals. These terminals must be supplied with an external power supply.
	JP5	INSERTED	Selects the STEP/DIR signal voltage to 5V

Step signal during the change of direction:

The 25 microsecond time can be configured in the RosettaCNC software.

Internal diagram of Stepper motor control outputs:

Below we will illustrate some useful wiring diagrams as an example for the design of the complete control system (electric panel).

In the following example we see a wiring diagram of three stepper drives. The HOME switches are also used as a limit for the direction of movement where the homing procedure is executed. For the other direction, uses three NC switches in series and connected with the LIM input.

In this case the correct setting of the inputs in the configuration panel will be:

The following outputs are available for the spindle control:

• Digital output for clockwise rotation control
• Digital output for counterclockwise rotation control
• Analog output for Speed variation

The choice of the digital outputs to use for these functions is performed in the “Outputs” panel in “RosettaCNC card settings” As shown in the picture:

The M3 or M4 codes will activate the outputs, M5 will disable them.

If RosettaCNC Board controls also the spindle rotation speed then you must connect the analog output 0÷10V to the analog input of the drive. In the maximum speed parameter, you must set the the speed reached by the drive to the maximum voltage of 10V.

The “Start Time” parameter if set delays the execution of the Gcode to allow the spindle to reach the set speed. This time is also used when turning off the spindle.
In RosettaCNC Board are available also two digital inputs that can be used to inform the Controller when the spindle has reached the set speed or when it's stopped. The following picture shows where to set the reference speed to 10V, The start time and the configuration of the inputs:


If the inputs are configured then the value in the start time parameter always indicates the minimum wait time although the logic level of the input does not require a wait.

There are several ways to design the control console. The following shows four examples:

• The easiest way is to always operate in the personal computer where the RosettaCNC software is installed. Here the Jogs, homing sequences, start and stop of Gcode programs, etc. will be controlled. Below is a graphical representation of the solution:
  .
  On the machine side only the ESTOP emergency button will be present (and possibly the reset button). In addition, MPG devices for override control (up to two devices) can be set up. In this case the value of the “Controller type” parameter is not significant.
• With the following solution, the following control devices are wired near the machine (in addition to the ESTOP emergency button): Joystick for the X-Y-Z jog. A button for selecting Jog Fast speeds. Possible button to modify the joystick control Z in A. The following is a graphical representation of the solution:
  .
  In addition an MPG device can be set up for control of override (feed, rapid, jog or spindle). In this case the value of the “Controller type” parameter must be set to “Dual Joystick”.
• With the following solution a handwheel is installed near the machine to check manual movements. During operation, if set in configuration, the handwheel can also be used to control the override (configuring the operation of the MPG1 device). Finally, always if set in configuration the handwheel button can also be used to perform a reset of the selected axis. The following is a graphical representation of the solution:
  .
  In addition to the flyer, an MPG device for override control can be set up near the machine (feed , rapid, jog or spindle). In this case, the value of the “Controller type” parameter must be set to “HandWheel A”.
• With the following solution, the following control devices are wired near the machine (in addition to the ESTOP emergency button): a Joystick for the jog + and Jog-. Up to 4 buttons for axis selection. A button to reset the axis. The following is a graphical representation of the solution:
  .
  In addition, an MPG device can be set up to control the override (feed, rapid, jog or spindle) . In this case the value of the “Controller type” parameter must be set to “Single Joystick”.

• Green Led POW, indicates that the device is powered.
• Green Led RUN, indicates that the device is working.
• Yellow Led STOP, indicates that the device is in a stop state.
• If flashes the Red Led ERROR, the controller is in an error state. You can try turning off and on again, if the problem persists, the product should be sent to technical support through the purchase channel used.

The firmware implements a series of virtual user inputs and outputs that can be used with Modbus ® communication.

Below is the list of virtual user inputs and their relationship with the numbering of virtual inputs in Modbus ®.

Below is the list of virtual user outputs and their relationship with the virtual output numbering in Modbus ®.
