Description
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).
Description
V/f CL-V/f OLV CLV AOLV
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 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 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 [ElapsedTime@1st to
4thFault] the cumulative operation time to two types of registers
at the same time for the MEMOBUS/Modbus communications.
