I have an allen bradley 1305 vfd that is currently in use with a slc 500 and provides two speeds by closing relay contacts with the plc on 15 16 and 17
They want more different speeds from it. I thought of putting resistors on it using relays on the pot terminals. Is there a better way ? http://literature.rockwellautomation.com/idc/groups/literature/documents/um/1305-um002_-en-p.pdf
Thank you
