V/f OLV
Displays the d-axis current for the motor at the previous fault.
All Modes
Displays the ASR output at the previous fault.
All Modes
Displays the temperature of the IGBTs at the previous fault.
All Modes
Displays the Power Cell at which a fault has occurred in hexadecimal.
All Modes
Displays the detected zero-phase voltage at the output side at the previous
fault.
All Modes
Displays the detected output voltage value at the previous fault.
All Modes
Displays the detected input voltage value at the previous fault.
All Modes
Displays the 1st to the 49th most recent faults.
After 49 faults have occurred in the drive, the 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 1st to the 49th most
recent faults occurred.
U4: Maintenance Monitors
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 ON.
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 power cell with the highest IGBTs temperature.
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 run.
