I definitly wouldn´t install the PLC and its IO cards in the same cabinet of such amount of VFD. Some advices (assuming there is only one cabinet): 1. Improve grounding inside the cabinet: use shorther, thicker ground cables for all devices, ensure analog cables are shielded and properly grounded. 2. Install a metal plate to separate the IO section from the VFD section. 3. Follow the wiring recommendations of these links: https://support.unitronics.com/index.php?/selfhelp/view-article/unitronics-vfd-quick-start-guide https://www.unitronicsplc.com/Download/SoftwareUtilities/General_Wiring_Guidelines.pdf 4. Change carrier frequency of some of the drives. -
Thanks for your help. I will try with USB cable on thursday. Note: The RUN led was orange blinking on PLC (Stop mode according to help). I've tried to shut off / restart it: RUN led became orange on, then after some time, orange blinking. -
First - attempt to use USB cable and ping than connect VNC to IP 169.254.0.1 You can check if this network exists after connecting USB cable to powered-on PLC: C:\Windows\System32>ipconfig Windows IP Configuration Ethernet adapter Ethernet 8: Connection-specific DNS Suffix . : Autoconfiguration IPv4 Address. . : 169.254.161.234 Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : -
Very near. I haven't USB cable with the right USB connector type here. I can find one for thursday. But if there's anything else that can be done on the plc, I can do it.
