U2-20
(8EH) Heatsink Temperature at
Previous Fault
Displays the temperature of the heatsink when the most recent fault occurred. Displayed as in
U4-08.

<10> The display resolution depends on the rated output power of the drive. Models 2A0018 to 2A0041 and 4A0009 to 4A0023 display values in
0.01 A units, while models 2A0059 to 2A0432 and 4A0030 to 4A0260 display values in 0.1 A units.
<31> Setting units are determined by the digital operator display unit selection (o1-03). When o1-03 = 0, the value is set in Hertz. When o1-03 = 4
or 5, the value is displayed in m/s. When o1-03 = 6, the value is displayed in ft/min.
<40> When checking the values of U1-03, U2-05 and U4-13 with the digital operator they are displayed in units of amperes, but when they are
checked using MEMOBUS communications, the monitor value in MEMOBUS communications is: displayed numeric value / 8192 × drive’s
rated current (A), from the condition “8192 (maximum value) = drive’s rated current (A)”.

5th to 10th Most Recent Fault
Displays the fifth to the tenth most recent faults.
After ten faults have occurred in the drive, data for the oldest fault is deleted. The most recent
fault appears in U3-01, with the next most recent fault appearing in U3-02. The data is moved to
the next monitor parameter every time a fault occurs. No signal output

<41>
Cumulative Operation Time
Displays the cumulative operation time of the drive. The value for the cumulative operation
time counter can be reset in parameter o4-01. Use parameter o4-02 to determine if the operation
time should start as soon as the power is switched on or only while the Up/Down command is
present. The maximum number displayed is 99999, after which the value is reset to 0. No signal output

Cooling Fan Operation Time Displays the cumulative operation time of the cooling fan. The default value for the fan
operation time is reset in parameter o4-03. This value will reset to 0 and start counting again
after reaching 99999.

Cooling Fan Maintenance Displays main cooling fan usage time in as a percentage of its expected performance life.
Parameter o4-03 can be used to reset this monitor. The fan should be replaced when this
monitor reaches 90%.
