Hi guys , new here and would really appreciate any help with a teco inverter. The inverter is controlling a 3 phase motor on a creaming machine. The issue I'm having is that I can't get the Plc that's controlling the inverter to control the inverters frequency. The controller will turn the inverter on through S1 and 24v connections on the terminals but only if I set the frequency of the inverter manually. I've set the "Frequency command source" to all available settings but nothing would work. On page 3-15 it shows the wiring diagram, I've wired the terminals "12v" and "com" on the "frequency control device" which corresponds the old inverter (Yaskawa V 1000 CIMR-VCBA0018BAA) page 45 connected to "A1" and "AC" but I'm not sure what to do now.
