📄 Configuration of C94 with UCCNC

Initial Step-by-Step Wiring and Testing of a C94 with UCCNC


The main objectives of these step-by-step instructions are:

  • Power the Board and e-stop, and test that the board activates/deactivates at the hardware level only with e-stop.
  • Install the UCCNC license and configure the pinout and functions of UCCNC supported by the C94. Then, test that UCCNC is communicating with the C94 successfully.
  • Enable and configure the Safety Charge Pump to make sure the C94 activates (green LED) when UCCNC becomes active (out of reset).

Software: UCCNC V 1.2115

STEP 1: Connect an E-Stop button to short the E-Stop terminals. 

  • This should give you a green LED while the board is powered and the e-stop is closed.
  • If not, check other possible fault conditions and make sure they are not active.

 

STEP 2: Make sure the controller is connected to an Ethernet port on the PC and powered with LEDs ON. 

 

STEP 3: The UCCNC license must be installed to establish the connection with the hardware. Replace the demo license that comes with the UCCNC installation with the license that you purchased.

 

STEP 4: Download and run the UC Utilityxxx program to establish the connection, set a fixed IP on the PC’s LAN card, and whitelist the device on the network. You may need to manually configure the LAN’s IPv4 protocol to use a fixed IP.

STEP 5: Configure UCCNC manually using these instructions:

You can also download and install the cnc4pc.com software to configure UCCNC. This software will configure all the pinouts and functions supported by the C94.

  • Select the profile of your preference, then click on 'Install'.


  • Finally, click on Close.


STEP 6: Start UCCNC, and it should show that it is licensed and should talk ok to the UC300ETH installed in the C94.

 

 

 

STEP 7: Final Test

  • Test the E-Stop by opening the circuit and confirming the green LED goes off.
  • You can now enable the SCHP back on by moving (JUMPER=ON), so it will be the control software that will enable the system.
