CLV
AOLV
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 actual MFDO terminal 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
V/f

OLV
CLV
AOLV
Shows the cumulative operation time of the drive at the fault that occurred most recently.
Use U4-01 [Cumulative Ope Time] to monitor the actual cumulative operation time.
Unit: 1 h
V/f
CL-V/f
OLV
CLV
AOLV
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
V/f
CL-V/f
OLV
CLV
AOLV
Shows the q-axis current of the motor at the fault that occurred most recently.
Use U6-01 [Iq Secondary Current] to monitor the actual q-Axis current of the motor.
Unit: 0.1 %
V/f
CL-V/f
OLV
CLV
AOLV
Shows the d-axis current of the motor at the fault that occurred most recently.
Use U6-02 [Id ExcitationCurrent] to monitor the actual d-Axis current of the motor.
Unit: 0.1 %
V/f
CL-V/f
OLV
CLV
AOLV
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 °
V/f
CL-V/f
OLV
CLV
AOLV
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
V/f
CL-V/f
OLV
CLV
AOLV
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).
V/f
CL-V/f
OLV
CLV
AOLV
Shows the fault history of the first to fourth most recent faults.
Note:
The drive saves the U3-01 to U3-04 [1st to 4th MostRecent Fault] fault histories to two types of
registers at the same time for the MEMOBUS/Modbus communications.
V/f
CL-V/f
OLV
CLV
AOLV
Shows the fault history of the fifth to tenth most recent faults.
