Cause : SIMOLINK telegram failure comes when communication on the SIMOLINK ring is disturbed due to faulty cable or hardware issue in drive.

  1. Check the fiber-optic cable ring.
  2. Check whether an SLB in the ring is without voltage.
  3. Check whether an SLB in the ring is faulty.
  4. Check P741 (SLB TlgOFF).
