V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
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 OLV OLV/PM AOLV/PM EZOLV OLV/PM
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 OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the heatsink temperature of the drive.
Unit: 1 °C
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Turns on all of the keypad LEDs to make sure that the LEDs operate correctly.
1. With U4-09 displayed, press
All LEDs on the keypad will turn on.
Note:
When Safety input 2 CH is open (STo), READY will flash.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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. 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 OLV OLV/PM AOLV/PM EZOLV OLV/PM
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
