I am installing a Motor Speed control "Danfoss VLT 2800". I am going to use Two digital signals from a PLC to the Drive, to give me Four fixed Motor speeds
For me to control the New Drive, I am using two 24v output siganls from the SLC 500 Alen Bradley PLC within the same Control panel as the new VLT 2800,
Can I input these signals straight into the Drive, or do I have to use Relays switched by the PLC and volt free contacts to utilise the Drive's own 24v Supply????
