Safety

  • Drive/power/encoder circuit: hazardous voltages may remain in the DC link after power-off. Lock out / tag out, wait for discharge per the drive documentation, and use qualified personnel only.

Common Causes

  • Error in SDB for configuring PROFIBUS/PROFINET.
  • Causes of the error: - 01 = SDB does not exist in source.
  • - 02 = SDB from source is too large.

Troubleshooting Steps

  1. 1Check the setting of MD 11240 $MN_PROFIBUS_SDB_NUMBER.
  2. 2If source = 100: Check directory _N_SDB_DIR in the passive file system.
  3. 3If source = 103-106: Check directories on CF card
  4. 4Switch control OFF - ON. Continuation: Alarms Drive and I/O alarms
