U4-07
(07D7)
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%.
10 V: 100%
U4-08
(0068)
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.

U4-10
(005C)
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. 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

U4-11
(005D)
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 4720
No signal output available
U4-14
(07D0)
PeakHold Output Freq
Displays the output frequency at which the peak value (rms) of the drive output current is held.
The peak hold current can be monitored by U4-13 [Peak Hold Current] .
The peak hold output frequency 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).
Unit: 0.01 Hz
No signal output available
U4-16
(07D8)
Motor oL1 Level
Shows the integrated value of oL1 [Motor Overload] as a percentage of oL1 detection level.
Unit: 0.1%
10 V: 100%
