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 Run command is present. The
maximum number displayed is 99999, after which the value is reset to 0.
Displays the number of times the Run command is entered. Reset the number
of Run commands using parameter o4-13. This value will reset to 0 and start
counting again after reaching 65535.
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.
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.
Displays main circuit capacitor usage time in as a percentage of their expected
performance life. Parameter o4-05 can be used to reset this monitor.
Displays the soft charge bypass relay maintenance time as a percentage of its
estimated performance life. Parameter o4-07 can be used to reset this monitor.
Displays IGBT usage time as a percentage of the expected performance life.
Parameter o4-09 can be used to reset this monitor.
Displays the heatsink temperature.
Lights all segments of the LED to verify that the display is working properly.
Monitors the drive output power. The value is shown as a 9 digit number
displayed across two monitor parameters, U4-10 and U4-11.
Example:
12345678.9 kWh is displayed as:
U4-10: 678.9 kWh
U4-11: 12345 MWh
Displays the highest current value that occurred during run.
Displays the output frequency when the current value shown in U4-13
occurred.
Shows the value of the motor overload detection accumulator. 100% is equal
to the oL1 detection level.
Displays the source for the frequency reference as XY-nn.
X: indicates which reference is used:
1 = Reference 1 (b1-01)
2 = Reference 2 (b1-15)
Y-nn: indicates the reference source
0-01 = Digital operator
1-01 = Analog (terminal A1)
1-02 = Analog (terminal A2)
1-03 = Analog (terminal A3)
2-02 to 17 = Multi-step speed (d1-02 to 17)
3-01 = MEMOBUS/Modbus communications
4-01 = Communication option card
5-01 = Pulse input
7-01 = DWEZ
Displays the frequency reference provided by MEMOBUS/Modbus
(decimal).
Displays the frequency reference input by an option card (decimal).
