Other error- and alarm messages, thefault causes and the appropriate counter-measures, are described in the Section “Fault- and alarm messages” of thedrive Instruction Manual.6.1 CBD Alarms and faults6.1.1 AlarmsAlarm A081:DeviceNet idle condition warningA zero length PZD data telegram has been received through either the poll or bit strobe I/O message channel. Thealarm will be reset when a normal length PZD data telegram is received.Effect:The telegram is ignored. Data which was last sent remains valid. Depending on the telegram failuremonitoring setting (P695), fault F082 can be initiated (DPR telegram failure).Counter-measures:♦ Check the DeviceNet bus master. Some PLCs will send an idle condition when they are put in the “program”mode.Alarm A083:Error warningErroneous DeviceNet CAN messages are received or sent and the internal fault counter has exceeded the alarmlimit.Effect:The erroneous CAN messages are ignored. Data which was last sent remains valid. If it involvesprocess data in the erroneous CAN messages, depending on the telegram failure monitoring setting(P695), fault F082 can be initiated (DPR telegram failure). There is no response in the drive if thePKW Object or other DeviceNet explicit messages are erroneous.Counter-measures:♦ Check and if required correct parameter P705 (baud rate) for every bus node.♦ Check the cable connection between the bus nodes♦ Check the cable shielding. Follow DeviceNet specifications.♦ Replace board CBDSiemens AG 477 759 4070 76 J AA-74 55SIMOVERTMASTERDRIVES Betriebsanleitung/OperatingInstructions
