All Modes
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.
All Modes
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.
All Modes
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%.
All Modes
Displays main circuit capacitor usage time in as a percentage of their expected performance life.
The capacitors should be replaced when this monitor reaches 90%. Parameter o4-05 can be used
to reset this monitor.
All Modes
Displays the soft charge bypass relay maintenance time as a percentage of its estimated
performance life. The soft charge relay should be replaced when this monitor reaches 90%.
Parameter o4-07 can be used to reset this monitor.
All Modes
Displays IGBT usage time as a percentage of the expected performance life. The IGBTs should
be replaced when this monitor reaches 90%. Parameter o4-09 can be used to reset this monitor.
All Modes
Displays the heatsink temperature.
All Modes
Lights all segments of the LED to verify that the display is working properly.
All Modes
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
All Modes
Displays the highest current value that occurred during a ride.
All Modes
Displays the output frequency when the current value shown in U4-13 occurred.
All Modes
Shows the value of the motor overload detection accumulator. 100% is equal to the oL1
detection level.
All Modes
Displays the level of the drive overload detection (oL2). A value of 100% is equal to the oL2
detection level.
All Modes
Displays the source for the speed reference as XY-nn.
X: indicates which reference is used:
1 = Reference 1 (b1-01)
Y-nn: indicates the reference source
0-01 = Digital operator
1-01 = Analog (terminal A1)
1-02 = Analog (terminal A2)
2-02 to 8 = Digital Inputs (d1-02 to 8)
3-01 = MEMOBUS/Modbus communications
4-01 = Communication option card
All Modes
Displays the speed reference provided by MEMOBUS/Modbus (decimal).
