U2-13
(008C)
DrvStat@PrevFault Shows the operation status of the drive 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 actual drive status.
bit 0 : During run
bit 1 : During zero-speed
bit 2 : During reverse
bit 3 : During fault reset signal input
bit 4 : During speed agreement
bit 5 : Drive ready
bit 6 : During minor fault detection
bit 7 : During fault detection

U2-14
(008D)
OpeTime@PreFault Shows the cumulative operation time of the drive at the fault that occurred most
recently.
Use U4-01 [Cumulative OpeTime] to monitor the actual cumulative operation time.
Unit: 1 h

U2-15
(07E0)
SFSFreq@PrevFault Shows the output frequency after soft start at the fault that occurred most recently.
Use U1-16 [SFS Output Frequency] to monitor the actual output frequency after soft
start.
Unit: 0.01 Hz
No signal output

U2-16
(07E1)
qCurrent@PrevFault Shows the q-axis current of the motor at the fault that occurred most recently.
Use U6-01 [Iq Sec Current] to monitor the actual q-Axis current of the motor.
Unit: 0.1 %
No signal output

U2-17
(07E2)
dCurrent@PreFault Shows the d-axis current of the motor at the fault that occurred most recently.
Use U6-02 [Id ExcCurrent] to monitor the actual d-Axis current of the motor.
Unit: 0.1 %
No signal output

U2-19
(07EC)
RotorDev@PrevFault Shows the amount of control axis deviation (Δθ) at the fault that occurred most recently.
Use U6-10 [ContAxisDeviation] to monitor the actual amount of control axis deviation
(Δθ).
Unit: 0.1 °
No signal output

U2-20
(008E)
DrvTemp@PreFault Shows the heatsink temperature at the fault that occurred most recently.
Use U4-08 [Heatsink Temperature] to monitor the actual temperature of the heatsink.
Unit: 1 °C

STPoSt@PrevFault Monitors conditions to detect STPo [Motor Step-Out Detected] faults. The bit for each
condition is displayed as ON or OFF.
bit 0 : Excessive current
bit 1 : Induced voltage deviation
bit 2 : d-axis current deviation
bit 3 : Motor lock at startup
bit 4 : Acceleration stall continue
bit 5 : Acceleration stall repeat
bit 6 : Not used (normal value of 0).
bit 7 : Not used (normal value of 0).

Name Description MFAO Signal Level Ref.
U3-01 to U3-10
(0090 - 0093)
(0804 - 0809)
1st to 10th Newest Fault Shows the fault history of the first to tenth most recent faults.
Note:
The drive saves the U3-01 to U3-04 [1st to 4th Newest Fault] fault histories to two
types of registers at the same time for the Modbus communications.
No signal output

U3-11 to U3-20
(0094 - 0097,
080E - 0813)
1st to 10th NewstFlt
Timing
Shows the cumulative operation time when the first to tenth most recent faults occurred.
Unit: 1 h
Note:
The drive saves the U3-11 to U3-14 [1st to 4th NewstFlt Timing] the cumulative
operation time to two types of registers at the same time for the Modbus
communications.
