Parameter List1111.17 U: MonitorsYASKAWA SIEPC71061753A GA500 Technical Manual 417No.(Hex.) Name Description MFAO Signal LevelU2-20(008E)Heatsink Temp @FaultShows the heatsink temperature at the fault that occurred most recently.Use U4-08 [Heatsink Temperature] to monitor the actual temperature of the heatsink.Unit: 1 °CNo signal output availableU2-21(1166)ExpertSTPo Detect @ FaultMonitors conditions to detect STPo [Motor Step-Out Detected] faults. The bit for each conditionis shown as = ON or = OFF.For example, U2-21 shows when the drive detects excessive current.bit0 : Excessive currentbit1 : Induced voltage deviationbit2 : d-axis current deviationbit3 : Motor lock at startupbit4 : Acceleration stall continuebit5 : Acceleration stall repeatbit6 : Not used (normal value of [ ]).bit7 : Not used (normal value of [ ]).No signal output available◆ U3: Fault HistoryNo.(Hex.) Name Description MFAO Signal LevelU3-01 to U3-04(0090 - 0093)(0800 - 0803)1st to 4th MostRecent FaultShows the fault history of the first to fourth most recent faults.Note:The drive saves the U3-01 to U3-04 [1st to 4th MostRecent Fault] fault histories to two typesof registers at the same time for the MEMOBUS/Modbus communications.No signal output availableU3-05 to U3-10(0804 - 0809)5th to 10th MostRecentFault Shows the fault history of the fifth to tenth most recent faults.No signal output availableU3-11 to U3-14(0094 - 0097)(080A - 080D)ElapsedTime@1st to4thFault Shows the cumulative operation time when the first to fourth most recent faults occurred.Unit: 1 hNote:The drive saves the U3-11 to U3-14 [ElapsedTime@1st to 4thFault] the cumulative operationtime to two types of registers at the same time for the MEMOBUS/Modbus communications.No signal output availableU3-15 to U3-20(080E - 0813)ElapsedTime@5th to10thFault Shows the cumulative operation time when the fifth to tenth most recent faults occurred.Unit: 1 hNo signal output available◆ U4: Maintenance MonitorsNo.(Hex.) Name Description MFAO Signal LevelU4-01(004C)Cumulative Ope TimeShows the cumulative operation time of the drive.Use parameter o4-01 [Elapsed Operating Time Setting] to reset this monitor. Use parameter o4-02[Elapsed Operating Time Selection] to select the cumulative operation times from:• The time from when the drive is energized until it is de-energized.• The time at which the Run command is turned ON.The maximum value that the monitor will show is 99999. After this value is more than 99999, thedrive automatically resets it and starts to count from 0 again.Unit: 1 hNote:The MEMOBUS/Modbus communication data is shown in 10 h units. Use register 0099H fordata in 1 h units.10 V: 99999 hU4-02(0075)Num of Run CommandsShows how many times that the drive has received a Run command.Use parameter o4-13 [RUN Command Counter @ Initialize] to reset this monitor. The maximumvalue that the monitor will show is 65535. After this value is more than 65535, the driveautomatically resets it and starts to count from 0 again.Unit: 110 V: 65535 timesV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLVV/f OLV OLV/PMOLV/PM AOLV/PM EZOLV
