MaintenenceENG Posted May 6, 2020 Report Share Posted May 6, 2020 I am stuck with trying to implement a servo motor, and not sure how to go from here. I have been using the example programs from the unitronics and i cannot get the programs to say the servo is connected. I have connected the CANBus wires according to the picture that i have attached that i found on the unitronics website. My group has never dealt with CAN networks before so we are all starting from scratch. I believe i have to use UniCAN Nodes but am not sure, currently i am just trying to just get the example program working, I am using the "Go to Position By Velocity Block" program. When I connect the computer to the PLC in online mode, no messages are dropped but none are received i attached a picture of the communications. Everywhere online i look for help i see that unilogic is great for this but all support I've found is for visilogic, not sure if I should switch to visilogic but I have been using unilogic. I have set up the plc, motor controller, and motor numbers in the project. The models are- Motor: UMM-0004BA-B4 Motor Drive: UMD- 0004B-B3 PLC: USP-070-B10 Quote Link to comment Share on other sites More sharing options...
MVP 2022 kratmel Posted May 6, 2020 MVP 2022 Report Share Posted May 6, 2020 You must connect +V CAN connector to the +24V, and -V CAN connector to the 0V(GND). CAN module must be powered via external (separated or not separated power supply). Quote Link to comment Share on other sites More sharing options...
MaintenenceENG Posted May 6, 2020 Author Report Share Posted May 6, 2020 i have added those wires to a 24V power supply but am still not getting the the servo to be marked as connected. There is an image on the program that shows the status of the motor, it constantly shows as motor disconnected. Quote Link to comment Share on other sites More sharing options...
