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.
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 value that was under hold 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: When the drive model changes, the display units for this parameter also change.
• 0.01 A units: B001 - B018, 2001 - 2042, 4001 - 4023
• 0.1A units: 2056 - 2082, 4031 - 4060
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%
Shows the selected frequency reference source.
The keypad shows the frequency reference source as "XY-nn" as specified by these rules:
X: External Reference 1/2 Selection [H1-xx = 2] selection status
• 1: b1-01 [Frequency Reference Selection 1]
• 2: b1-15 [Frequency Reference Selection 2]
Y-nn: Frequency reference source
• 0-01: Keypad (d1-01 [Reference 1])
• 1-00: Analog input (unassigned)
• 1-01: MFAI terminal A1
• 1-02: MFAI terminal A2
• 2-02 to 2-17: Multi-step speed reference (d1-02 to d1-17 [Reference 2 to 16, Jog Reference])
• 3-01: MEMOBUS/Modbus communications
• 4-01: Communication option card
• 5-01: Pulse train input
• 7-01: DriveWorksEZ
• 9-01: Up/Down command
Shows the frequency reference sent to the drive from the MEMOBUS/Modbus communications as a
decimal.
Unit: 0.01%
Shows the frequency reference sent to the drive from the communication option as a decimal.
Unit: 0.01 %
