4 DeviceNet Option ComponentsYASKAWA ELECTRIC SIEP C730600 43A YASKAWA AC Drive-Option Card DeviceNet Technical Manual 9 Power-Up DiagnosticsAn LED test is performed each time the drive is powered up. The initial boot sequence may take several seconds. Afterthe LEDs have completed the DeviceNet diagnostic LED sequence, the DeviceNet Option is successfully initialized. TheLEDs then assume operational conditions as shown in Table 3.Table 4 Power-Up Diagnostic LED Sequence Set the DeviceNet Option MAC ID Parameter F6-50, MAC ID SettingRange: 0~64The MAC ID is set by drive parameter F6-50. A MAC ID setting in the range of 0~63 is considered a valid MAC ID. Avalue other than 0~63 indicates the MAC ID is settable over the network.The DeviceNet Option SI-N3 reads the MAC ID value from parameter F6-50 upon power-up and upon a network reset. Set the DeviceNet Option Baud RateThe DeviceNet Option will support standard baud rates of 125 k bit/s, 250 k bit/s, and 500 k bit/s.Table 5 Parameter F6-51 Baud Rate Setting Auto Baud Rate Sensing (F6-51 = 4)Setting parameter F6-51 = 4, "Auto Detect" causes the DeviceNet Option to determine the data rate of the DeviceNetNetwork and configure itself appropriately.Note: The auto baud capability will only be valid when there is more than one node physically on the DeviceNet network segment. Thedrive digital operator will display “bUS” and the DeviceNet option LEDs will be (NS-OFF and MS=Solid Green) as long as autobaud rate sensing fails to detect the baud rate.NS– OFF Offline or Power supplyOFF –Green ON Online communicationsestablished Device is on-line and has connections in the established state.Green Flashing Online communications notestablishedDevice is on-line but has no connections in the established state.Dup Mac-ID test has been passed, is on-line but has no openconnections to other nodes.Red ON Communications errorAn error occurred that disables DeviceNet communications.MAC ID duplicationBus Off detectedRed Flashing Communications time-out A communications time-out occurred with the master.Green/Red Flashing Communication faultedSpecific communication faulted device.The device has detected a network access error and is in thecommunications faulted state.The device has then received and accepted an Identify communicationfault request-long protocol message.Sequence Module Status (MS) Network Status (NS) Time (ms)1 GREEN OFF 2502 RED OFF 2503 GREEN GREEN 2504 GREEN RED 2505 GREEN OFF -Description Value125 k bit/s 0250 k bit/s 1500 k bit/s 2Programmable From Network 3Auto Detect 4Name Indication Operating Status RemarksColor Status
