Hello sandy; The document attached to this link will show in detail the USS connection to a MM420, which is very similar to the MM440 in that respect. What information is available about using USS Protocol with the MM420? Look on page 11 for a description of every bit in the Control Word (STW) and on page 12 to see how the Speed Reference word (HSW) is constructed. Note that you must send each of the Control and Speed reference words complete, that is you cannot send a bit over USS (or Profibus for that matter). Hope this helps,àDaniel Chartier |
