IGBT Maintenance
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%.

Heatsink
Temperature
Shows the heatsink temperature of the drive.
Unit: 1 °C
10 V: 100 °C -
U4-09
(005E)
LED Check
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 with U4-09 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.

kWh, Lower 4
Digits
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

kWh, Upper 5
Digits
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

U4-13
(07CF)
Peak Hold Current
Shows the hold value of the peak value (rms) for the drive output
current.
Use U4-14 [PeakHold Output Freq] to show the drive output
frequency at the time that the drive holds the output current.
The drive will hold the peak hold current at the next start up and
restart of the power supply.
The drive keeps the held value during baseblock (during stop).
The keypad shows the value of U4-13 in amperes (A). When
looking at the monitor through MEMOBUS/Modbus
communications, the current is “8192 = drive rated current (A).”
Calculate the current from the monitor value that is in at
MEMOBUS/Modbus communications using “Numerals being
displayed / 8192 × drive rated current (A).
Unit: Determined by the drive model.
• 0.01 A: 2004 to 2042, 4002 to 4023
• 0.1 A: 2056 to 2415, 4031 to 4675
