U2-13
(008C)
Operation Status @ Fault
Shows the status of the MFDO terminals at the most recent fault where 1 = (ON) and 0 = (OFF).
For example, U2-13 shows “00000001” during run.
Use U1-12 [Drive Status] to monitor the 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
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 %
No signal output available
U2-17
(07E2)
d-Axis Current@Fault
Shows the d-Axis current of the motor at the fault that occurred most recently.
Use U6-02 [Id ExcitationCurrent] to monitor the d-Axis current of the motor.
Unit: 0.1 %
No signal output available
U2-19
(07E4)
ControlDeviation@Flt
Shows the amount of control axis deviation (Δθ) at the fault that occurred most recently.
Use U6-10 [ContAxisDeviation Δθ] to monitor the actual amount of control axis deviation (Δθ).
Unit: 0.1 °
No signal output available
U2-20
(008E)
Heatsink Temp @Fault
Shows the heatsink temperature at the fault that occurred most recently.
Use U4-08 [Heatsink Temperature] to monitor the temperature of the heatsink.
Unit: 1 °C
No signal output available
U2-21

Expert
STPo Detect @ Fault
Monitors conditions to detect STPo [Motor Step-Out Detected] faults. The bit for each condition is
shown as ON or OFF.
bit0 : Excessive current
bit1 : Induced voltage deviation
bit2 : d-axis current deviation
bit3 : Motor lock at startup
bit4 : Acceleration stall continue
bit5 : Acceleration stall repeat
bit6 : Not used (normal value of 0).
bit7 : Not used (normal value of 0).
