U1-19
(0066)
MEMOBUS/Modbus Error
Code
Shows the contents of the MEMOBUS/Modbus communication error where 1 = “error” and 0 =
“no error”.
For example, U1-19 shows “00000001” when there is a CRC error.
bit0 : CRC Error
bit1 : Data Length Error
bit2 : Not used (normal value of 0).
bit3 : Parity Error
bit4 : Overrun Error
bit5 : Framing Error
bit6 : Timed Out
bit7 : Not used (normal value of 0).

U2-01
(0080)
Current Fault
Shows the fault that the drive has when viewing the monitor.
No signal output available
U2-02
(0081)
Previous Fault
Shows the fault that occurred most recently.
No signal output available
U2-03
(0082)
Freq Reference@Fault
Shows the frequency reference at the fault that occurred most recently.
Use U1-01 [Frequency Reference] to monitor the frequency reference value.
Unit: 0.01 Hz
No signal output available
U2-04
(0083)
Output Freq @ Fault
Shows the output frequency at the fault that occurred most recently.
Use U1-02 [Output Frequency] to monitor the actual output frequency.
Unit: 0.01 Hz
No signal output available
U2-05
(0084)
Output Current@Fault
Shows the output current at the fault that occurred most recently.
Use U1-03 [Output Current] to monitor the output current. The keypad shows the value of U1-03
in amperes (A).
When you use MEMOBUS/Modbus 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 MEMOBUS/Modbus communication current value shown in the monitor.
Unit: When the drive model changes, the display units for this parameter also change.
• 0.01 A: 2004 - 2042, 4002 - 4023
• 0.1 A: 2056 - 2415, 4031 - 4675
