Table 5-114: Maintenance Parameters
Parameter Display Function Units
U04-01 Drv Elapsed Time Displays the cumulative operation time of the drive. The
value for the cumulative operation time counter can be reset
in parameter O03-01. Use parameter O03-02 to determine if
the operation time should start as soon as the power is
switched on or only while the Run command is present. The
maximum number displayed is 99999, after which the value
is reset to 0.
Hrs
U40-03 Fan Elapsed Time Displays the cumulative operation time of the cooling fan.
The default value for the fan operation time is reset in
parameter O03-03. After the count reaches 99999, the value
will reset to 0 and start counting again.
Hrs
U04-04 Fan Life Mon Displays main cooling fan usage time in as a percentage of
its expected performance life. Parameter O03-03 can be
used to reset this monitor.
%
U04-05 Cap Life Mon Displays main circuit capacitor usage time in as a
percentage of their expected performance life. Parameter
O03-05 can be used to reset this monitor.
%
U04-06 ChgCirc Life Mon Displays the soft charge bypass relay maintenance time as
a percentage of its estimated performance life. Parameter
O04-07 can be used to reset this monitor.
%
U04-07 IGBT Life Mon Displays IGBT usage time as a percentage of the expected
performance life. Parameter O03-09 can be used to reset
this monitor.
%
U04-08 Heatsink Temp Displays the heatsink temperature. °C
U04-09 LED Oper Check Lights all segments of the LED to verify that the display is
working properly.
--
U04-10 kWh Lower 4 dig Monitors the drive output power. The value is shown as a 9
digit number displayed across two monitor parameters,
U04-10 and U04-11.
kWH
U04-11 kWh Upper 5 dig -- MWH
U04-12 CPU Occup Rate Displays the amount of space being used in the CPU. %
U04-13 Current PeakHold Displays the highest current value that occurred during run. A
U04-14 Freq@ I PeakHold Displays the output frequency when the current value shown
in U04-13 occurred.
Hz
U04-16 Motor OL1 Level Shows the value of the motor overload detection
accumulator. 100% is equal to the OL1 detection level.
Accumulator is reset when drive power is cycled.
%
U04-17 Drive OL2 Level 100% = OL2 detection level %
U04-18 Reference Source Displays the source for the frequency reference as XY-nn. --
U04-19 MEMOBUS Freq Ref Displays the frequency reference provided by MEMOBUS/
Modbus (decimal).
%
U04-20 Option Freq Ref Displays the frequency reference input by an option card
(decimal).
%
U04-21 Run Cmd Source Displays the source for the Run command as XY-nn. --
U04-22 MEMOBUS Ref Reg Displays the drive control data set by MEMOBUS/Modbus
communications register no. 0001H as a four-digit
hexadecimal number.
--
U04-23 Option Ref Reg Displays drive control data set by an option card as a four-
digit hexadecimal number.
--
U04-32* Motor Temp (NTC) Displays the motor temperature (NTC).
U04-32 will display “20 °C” when a multi-function analog
input is not set for motor thermistor input (H01-xx = 17H).
--
U04-37* OH Alarm Axis Displays the module where the oH alarm occurred as a
binary number.
BIN
