No signal outputavailable –u U4: Maintenance MonitorsNo.(Addr.Hex) Name Description Analog Output Level UnitU4-01(4C) Cumulative OperationTimeDisplays the cumulative operation time of the drive. The value for thecumulative operation time counter can be reset in parameter o4-01. Useparameter o4-02 to determine if the operation time should start as soon asthe power is switched on or only while the Run command is present. Themaximum number displayed is 99999, after which the value is reset to 0.No signal outputavailable 1 hU4-02(75) Number of RunCommandsDisplays the number of times the Run command is entered. Reset thenumber of Run commands using parameter o4-13. This value will reset to0 and start counting again after reaching 65535.No signal outputavailable 1 TimeU4-03(67) Cooling Fan OperationTimeDisplays the cumulative operation time of the cooling fan.
