U2-09
(0088)
Output Power @ Fault
Shows the output power at the fault that occurred most recently.
Use U1-08 [Output Power] to monitor the output power.
Unit: 0.1 kW
No signal output available
U2-10
(0089)
Torque Ref @ Fault
Shows the torque reference at the fault that occurred most recently as a percentage of the motor rated
torque.
Use U1-09 [Torque Reference] to monitor the torque reference.
Unit: 0.1%

U2-11
(008A)
Input Terminal Status @
Fault
Shows the status of the MFDI terminals at the most recent fault where = ON and = OFF.
For example, U2-11 shows when terminals S1 and S3 are ON.
Use U1-10 [Input Terminal Status] to monitor the actual MFDI terminal status.
bit0 : Terminal S1
bit1 : Terminal S2
bit2 : Terminal S3
bit3 : Terminal S4
bit4 : Terminal S5
bit5 : Terminal S6
bit6 : Terminal S7
bit7 : Not used (normal value of [ ]).

U2-12
(008B)
Output Terminal Status @
Fault
Shows the status of the MFDO terminals at the most recent fault where = ON and = OFF.
For example, U2-12 shows when terminals MA and P2 are ON.
Use U1-11 [Output Terminal Status] to monitor the actual MFDO terminal status.
bit0 : Terminal MA/MB-MC
bit1 : Terminal P1-C1
bit2 : Terminal P2-C2
bit3 : Not used (normal value of [ ]).
bit4 : Not used (normal value of [ ]).
bit5 : Not used (normal value of [ ]).
bit6 : Not used (normal value of [ ]).
bit7 : Not used (normal value of [ ]).
No signal output available
U2-13
(008C)
Operation Status @ Fault
Shows the status of the MFDO terminals at the most recent fault where = ON and = OFF.
For example, U2-13 shows during run.
Use U1-12 [Drive Status] to monitor the actual MFDO terminal status.
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
No signal output available
U2-14
(008D)
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
