Description
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 4Digits] 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 OutFreq] 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 Modbus communications, the current is "8192 = drive rated current (A)."
Calculate the current from the monitor value that is in at Modbus communications using
"Numerals being displayed / 8192 × drive rated current (A).
Unit: Determined by the drive model.
• 0.01 A: 4002 to 4023
• 0.1 A: 4031 to 4675
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).

Shows the selected frequency reference source.
The keypad shows the frequency reference source as "XY-nn" as specified by these
rules:
X: Ext Ref 1/2 [H1-xx = 9] selection status
• 1: b1-01 [Freq. Ref. Sel. 1]
• 2: b1-15 [Freq. Ref. Sel. 2]
Y-nn: Frequency reference source
• 0-01: Keypad (d1-01 [Reference 1])
• 1-00: Analog input (unassigned)
• 1-01: MFAI terminal AI1
• 1-02: MFAI terminal AI2
• 1-03: MFAI terminal AI3
• 2-02 to 2-17: Multi-step speed reference (d1-02 to d1-17 [Reference 2 to Reference
16, and Jog Reference])
• 3-01: Modbus communications
• 4-01: Communication option card
• 5-01: Pulse train input
• 7-01: Q2pack
• 9-01: Up/Down command
Shows the frequency reference sent to the drive from the Modbus communications as a
decimal.
Unit: 0.01%
Shows the frequency reference sent to the drive from the communication option as a
decimal.
