Good morning, we have done an attempt using TO_Positioning axis for a kind of machine we install, normally we just use the encoder and the reference speed from the plc to control the positioning. So we have: - CPU 1515 - TIA PORTAL 15.1 upd 4 - 2x G120 C - 1x multi-turn encoder (not siemens) (vertical axis) - 1x laser (not siemens) (horizontal axis) they are communicating with the PLC wireless through Scalance. (for the laser I am simulating the telegram 81 from the plc) I have configured all and try to move but I am not getting good results, if I increase a lot the Kp factor I get the axis to move but: - the actual speed is not the one I set - the axis moves quite longer after I deactivate the Jog command - the positioning is not right, it stops quite before, after... I attach some traces where you can see these behaviours. I have read all the manuals and done a lot of tries changing the parameters... but with no results, I wanted to understand, is there something wrong on the set up? it is possible to do what we have to do with this hardware or there is something I am missing?
