  1. My subcontractor use ABB ACS580 instead of ACS880. They argue that can program to control crane with it. Load capacity and motor power is no problem here, but the purpose of inverter I concern here. Is there any advice?
  2. Dear All   Sorry for my English I have Siemens CM1241 (picture attach) and need to communicate with Intellisys XE 90 via Modbus RTU, period. The problem is, form XE 90 the connector is Phoenix Contact 2-Position Screw Plug Connectors MC 1,5/ 2-ST-3,81 1803578,or in other word, only 2 contacts form P9 COM1 = L1 , L2 (picture attach).
