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 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

Byp Inp Terminal Status @
Fault
Shows the status of the bypass digital input terminals at the most recent fault where 1 = (ON) and 0 =
(OFF).
For example, U2-11 shows “00000011” when terminals S1 and S2 are ON.
Use Ub-02 [Bypass Digital Input Status] to monitor the terminal status.
bit 0 : Terminal S1
bit 1 : Terminal S2
bit 2 : Terminal S3
bit 3 : Terminal S4
bit 4 : Terminal S5
bit 5 : Terminal S6
bit 6 : Terminal S7
bit 7 : Not used (normal value of 0).

U2-12
(008B)
Byp Relay Status @ Fault Shows the status of the bypass digital output terminals at the most recent fault where 1 = (ON) and 0
= (OFF).
For example, U2-12 shows “00000011” when terminals M1 and M3 are ON.
Use Ub-02 [Bypass Digital Output Status] to monitor the terminal status.
bit 0 : Terminals M1-M2
bit 1 : Terminals M3-M4
bit 2 : Terminals M5-M6
bit 3 : Not used (normal value of 0).
bit 4 : Not used (normal value of 0).
bit 5 : Not used (normal value of 0).
bit 6 : Not used (normal value of 0).
bit 7 : Fault relay MA/MB-MC

U2-13
(008C)
Bypass Status @ Fault Shows the status of the bypass at the most recent fault where 1 = (ON) and 0 = (OFF).
For example, U2-13 shows “00000001” during run.
Use Ub-05 [Bypass Status 1] to monitor the bypass.
bit0 : During Run
bit1 : During zero-speed
bit2 : During reverse
bit3 : During fault reset signal input
bit4 : During speed agreement
bit5 : Drive ready
bit6 : During minor fault detection
bit7 : During fault detection

Elapsed Time @ Fault Shows the cumulative operation time of the drive at the fault that occurred most recently.
Use U4-01 [Cumulative Ope Time] to monitor the cumulative operation time.
Unit: 1 h
No signal output available
U2-15
(07E0)
SFS Output @ Fault Shows the output frequency after soft start at the fault that occurred most recently.
Use U1-16 [SFS Output Frequency] to monitor the output frequency after soft start.
Unit: 0.01 Hz
No signal output available
U2-16
(07E1)
q-Axis Current@Fault Shows the q-Axis current of the motor at the fault that occurred most recently.
Use U6-01 [Iq Secondary Current] to monitor the q-Axis current of the motor.
Unit: 0.1 %
