Yes. The inverter is providing encoder feedback. The encoder feedback goes through a ULN2003A pin 1, 2, 8 and pin 15,16 is connected to MD888 input 5,6. Pin 8 is connected to power supply 0VDC. First scan has setsystem 4,3. Anything wrong with the setup? The wire from inverter to ULN to PLC is not shielded. Any issues with that? Should not be an issue since input 3,4 is ok, right? Thanks.
