Error Removal

Info1 = 1
  • Check cabling

Info1 = 4
  • Check configuration of hardware synchronisation ID34026 'BUS mode attribute' in all devices
  • Check ID 2 'SERCOS cycle time' in all devices
  • Check cabling and terminator
  • When using the AMK adaptor AP-CI4 (O778), the resistors R1 and R2 must be equipped

Info1 = 5
  • Check configuration of hardware synchronisation ID34026 'BUS mode attribute' in all devices.
    Only one sender of hardware synchronisation cycle may be active.

Info1 = 11
  • NMT 'OPERATIONAL' received but basic device synchronisation not finished.
    I. e. the switching to 'OPERATIONAL' must be delayed.
    On AMK CAN master devices, this can be done by means of ID34026 by activating a run-up delay.
