I am using a USC-B5-R38 to run two inverters UMI-022BE-B1 most of the time I try to start them running with "VFD Run frequency Mode" the output code becomes -4 (goes through 2 before) The VFDs are active, Enable communication is on vfd is connected = 1 Enable periodic status Read = 1 I can download and upload profiles but trying to get the inverters running nearly always gives me error nr -4 "Communication timeout exceeded" .

Hello! I am a senior at UNew Haven in CT, currently building a machine that should mix gravel and water. I am a mechanical engineer so I have no idea what to do or where to begin! I am using the Unitronics tutorials but they are long and my time is limited We are using a VFD and V570 with PLC and HMI. I need the PLC to: 1. Move a linear actuator up and down 2. Using the VFD, to control the speed of the mixer 3. Control the duration of mixing (Created a preset keypad timer but not sure how to make number buttons and how to embed them to the keypad.) Any help or guidance would be very much appreciated Best
VFD, inverter, AC drive - engineers call these adjustable speed drives by different names, but all use them to control motor speed and torque. Now, you can obtain your VFDs from the same supplier as your PLC + HMI controllers. Unitronics VFDs can be used as a stand-alone product, or as part of a complete All-in-One package with our PLC+HMI controllers: UniStream®, Vision™ and Samba™. This simplifies workflow by enabling you to: Obtain your VFDs, PLC + HMI controllers and related components, as well as technical support, from a single supplier. Operate your VFD directly from the controller’s HMI panel Use the same programming software as the PLC control and HMI application, to: Set-up and configure multiple VFDs in a snap Monitor and debug your VFD Remotely Access your VFD For more information, check out the VFD page in our website: https://unitronicsplc.com/vfd-variable-frequency-drive/
Hello all. I'm new programmer with Unitronics PLC. At moment trying to communicate USP-104-B10 with VFD ATV630 series by Schneider Electric, but unfortunately for me unsuccessfully. In PLC communication created Scanner and Adapter, add strucs with global tags according manual https://download.schneider-electric.com/files?p_enDocType=User+guide&p_File_Id=9346677116&p_File_Name=ATV600_EthernetIP_Modbus_TCP_Manual_EN_EAV64328_03.pdf&p_Reference=EAV64328 But I do not understand clearly what I need add in Ladder to read all needed parameters, for example, every 5 secs and how to CALL it? Maybe one of you have example of program with successful communication? I would be very appreciated. Thank you in advance for your help and reply
