All Modes
Displays the first to the fourth most recent faults.
All Modes
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.
All Modes
Displays the cumulative operation time when the first to the fourth most recent faults occurred.
All Modes
Displays the cumulative operation time when the fifth to the tenth most recent faults occurred.
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 Run command is present.
The maximum number displayed is 99999, after which the value is reset to 0.
All Modes
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.
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.
Parameter o4-05 can be used to reset this monitor. The capacitor should be replaced when this
monitor reaches 90%.
All Modes
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. The soft charge bypass
relay should be replaced when this monitor reaches 90%.
All Modes
Displays IGBT usage time as a percentage of the expected performance life. Parameter o4-09
can be used to reset this monitor. The IGBT should be replaced when this monitor reaches 90%.
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 cumulative output power usage. 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 run.
Note: The unit is expressed in 1 A for models CIMR-A4A0930 and 4A1200.
