gerard339 Posted August 11, 2019 Report Share Posted August 11, 2019 Hi All, I want to control an Invertek VSD using Modbus communication similar to link below. I need a cable connect the drive to the V570 which needs a RJ45 on drive end and RJ11 on V570 end. Does anybody know the pinout of the RJ45 - RJ11 cable please? Thanks in advance...

MVP 2023 Ausman Posted August 11, 2019 MVP 2023 Report Share Posted August 11, 2019 I found this in one minute by googling Invertek VFD pinouts, going to the second suggestion that was the manual 82-P2MAN-IN Optidrive P2 User Guide V1.20.pdf and looking at the index, which clearly showed RJ45 connector pin assignment. Looked at other units and it appears they all use the same style. There is also a topic on the forum: http://forum.unitronics.com/topic/5597-v700-and-invertek-optidrive-e3-controlled-via-rs-485/ Aus Link to comment Share on other sites More sharing options...
gerard339 Posted August 11, 2019 Author Report Share Posted August 11, 2019 Ausman, Thanks for your reply. In the video I sent they went from a rj45 to rj11. Rj45 has 8 pins and rj11 has 6 pins. I need to find out how these are configured and how many wires are actually used? Regards, Gerard Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted August 11, 2019 MVP 2023 Report Share Posted August 11, 2019 It so happens that we are an Invertek distributor in the US. We found you can actually power a Samba from the drive, which is really handy when all you have available is 480V. Here's what we did to get RS485 using a standard Ethernet cable- Joe T.

MVP 2023 Ausman Posted August 11, 2019 MVP 2023 Report Share Posted August 11, 2019 And adding to what Joe says, if you look at the how Unitronics outputs 485 across the Vision system you would understand the 6 pin RJ11, and that you only use 2 lines.
