Description
V/f CL-V/f OLV CLV AOLV
Displays the usage time of the IGBT as a percentage of the
replacement life of the IGBT.
Parameter o4-09 [IGBT Maintenance Setting] can be used to reset
this monitor.
Unit: 1%
Note:
Replace the drive when this monitor reaches 90%.
V/f CL-V/f OLV CLV AOLV
Displays the heatsink temperature of the drive.
Unit: 1 °C
V/f CL-V/f OLV CLV AOLV
Lights all segments of the LEDs on the keypad and LED Status
Ring light to verify that the display is working properly.
Note:
The internal status of the drive cannot be determined when the
board for the LED Status Ring is damaged. Do not rely on the
LED Status Ring alone to determine the status of the drive and
motors.
1. Set o2-24 = 0 [LED Light Function Selection = Both Enable].
2. With U4-09 displayed, press
All LEDs on the keypad and LED Status Ring will glow.
Note:
When Safety input 2 CH is open (STo), READY will flash.
V/f CL-V/f OLV CLV AOLV
Displays the lower 4 digits of the watt hour value for the drive.
Unit: 1 kWh
Note:
The watt hour is displayed in 9 digits. Parameter U4-11 [kWh,
Upper 5 Digits] displays the upper 5 digits and U4-10 displays
the lower 4 digits.
Example for 12345678.9 kWh:
U4-10: 678.9 kWh
U4-11: 12345 MWh
V/f CL-V/f OLV CLV AOLV
Displays the upper 5 digits of the watt hour value for the drive.
Unit: 1 MWh
Note:
The watt hour is displayed in 9 digits. Parameter U4-11 displays
the upper 5 digits and U4-10 [kWh, Lower 4 Digits] displays the
lower 4 digits.
Example for 12345678.9 kWh:
U4-10: 678.9 kWh
U4-11: 12345 MWh
V/f CL-V/f OLV CLV AOLV
Displays the hold value of the peak value (rms) for the drive output
current.
The drive output frequency at the time the output current is held can
be monitored by U4-14 [PeakHold Output Freq].
The peak hold current will be cleared at the next startup and restart
of the power supply. The drive keeps the value that was under hold
during baseblock (during stop).
The value of U4-13 appears in amperes (A) on the keypad. When
viewing via MEMOBUS/Modbus communications, the current is
"8192 = drive rated current (A)." Current can be calculated from the
monitor value present at MEMOBUS/Modbus communications
using "Numerals being displayed / 8192 × drive rated current (A)."
Unit: Determined by the drive model.
• Models 2004 to 2042, 4002 to 4023: 0.01 A
• Models 2056 to 2415, 4031 to 4726: 0.1 A
