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%.
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%.
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%.
Shows the heatsink temperature of the drive.
Unit: 1 °C
Turns on the LED Status Ring and all of the keypad LEDs to make sure that the LEDs operate
correctly.
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.
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
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
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 you use serial communications to show
the monitor, the current is "8192 = drive rated current (A)." Use the formula: "Numerals being
displayed / 8192 × drive rated current (A)" to use the serial communication current value shown in
the monitor.
Unit: Determined by the drive model.
• 0.01 A: 2011 to 2046, 4005 to 4014
• 0.1 A: 2059 to 2273, 4021 to 4302
Shows 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
Shows the integrated value of oL1 [Motor Overload] as a percentage of oL1 detection level.
Unit: 0.1%
