V/f CL-V/f OLV CLV AOLV
Shows the cumulative operation time of the cooling fans.
Use parameter o4-03 [Fan Operation Time Setting] to reset this monitor. The maximum value that
the monitor will show is 99999. After this value is more than 99999, the drive automatically resets
it and starts to count from 0 again.
Unit: 1 h
Note:
The MEMOBUS/Modbus communication data is shown in 10 h units. Use register 009BH for
data in 1 h units.
V/f CL-V/f OLV CLV AOLV
Shows the cumulative operation time of the cooling fans as a percentage of the replacement life of
the cooling fans.
Use parameter o4-03 [Fan Operation Time Setting] to reset this monitor.
Unit: 1%
Note:
Replace the cooling fans when this monitor is 90%.
V/f CL-V/f OLV CLV AOLV
Shows the operation time of the electrolytic capacitors for the main circuit and control circuit as a
percentage of the replacement life of the electrolytic capacitors.
Use parameter o4-05 [Capacitor Maintenance Setting] to reset this monitor.
Unit: 1%
Note:
Replace the electrolytic capacitor when this monitor is 90%.
V/f CL-V/f OLV CLV AOLV
Shows the operation time of the soft charge bypass relay as a percentage of the replacement life of
the soft charge bypass relay.
Use parameter o4-07 [Softcharge Relay Maintenance Set] to reset this monitor.
Unit: 1%
Note:
Replace the drive when this monitor is 90%.
V/f CL-V/f OLV CLV AOLV
Shows the operation time of the IGBTs as a percentage of the replacement life of the IGBTs.
Set parameter o4-09 [IGBT Maintenance Setting] to reset this monitor.
Unit: 1%
Note:
Replace the drive when this monitor is 90%.
V/f CL-V/f OLV CLV AOLV
Shows the heatsink temperature of the drive.
Unit: 1 °C
V/f CL-V/f OLV CLV AOLV
Turns on the LED Status Ring and all of the keypad LEDs to make sure that the LEDs operate
correctly.
Note:
A damaged LED Status Ring board will prevent an accurate estimate of the internal status of
the drive. Do not use only the LED Status Ring to estimate the status of the drive and motors.
1. Set o2-24 = 0 [LED Light Function Selection = Enable Status Ring & Keypad LED].
2. Push when U4-09 is the top monitor shown on the keypad.
All LEDs on the keypad and LED Status Ring will turn on.
Note:
When Safety input 2 CH is open (STo), READY will flash.
V/f CL-V/f OLV CLV AOLV
Shows the lower 4 digits of the watt hour value for the drive.
Unit: 1 kWh
Note:
The watt hour is displayed in 9 digits. Monitor U4-11 [kWh, Upper 5 Digits] shows the upper
5 digits and U4-10 shows 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
Shows the upper 5 digits of the watt hour value for the drive.
Unit: 1 MWh
Note:
Monitor U4-11 shows the upper 5 digits and U4-10 [kWh, Lower 4 Digits] shows the lower 4
digits.
Example for 12345678.9 kWh:
U4-10: 678.9 kWh
U4-11: 12345 MWh
