  1. Has anyone mounted a 2HP Unitronics VFD in a NEMA 4 Enclosure? Most of our applications require a VFD with a NEMA 4 rating. In the past, we have used a VFD that was rated for a NEMA 4 environment and so we had no need to have an enclosure. With the new Unitronics VFD, we would like to use it instead but to meet the area classification, we would need to mount it in a NEMA 4 enclosure and we would like to keep the enclosure size to a minimum. Can anyone tell me what the smallest enclosure size can be if the ambient temperature is about 105 deg. max and there is no cooling fan? The only think ins
  2. I am using a UMI-022BE-B1 controled through modbus to lift trash bins (on a truck) My problem is that when I am lifting a load and stop the machine fall back around 15 cm before stoping (see picture) I used to run the same machine with Omron inverters there I set the Injector DC-Breaking to stop and hold the load while the mecanical break took hold. But I am gettin the feeling that the Unitronics DC-Braking setting are mostly cosmetic since no matter how I play with them nothing happens. I tried using P013. Short Circut breaking. Both at 75% and 100% power for 3 second and the on
  3. 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" . (mod edited out your email address, Daniel)
  4. 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 w
  5. 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 f
  6. 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.
