Fault Name
1. DC BUS voltage is lower than Pr. 06-00 setting
Low-voltage at stop
(LvS)
2. Hardware failure in voltage detection
Action and Reset
Pr. 06-00 (Default = depending on the model)
Immediately act when DCBUS voltage is lower than Pr. 06-00
N/A
Manual/ auto
230V series:
–
Frame A D = Lv level + 30V
Frame E and above = Lv level + 40V
460V series:
–
Frame A D = Lv level + 60V
Frame E and above = Lv level + 80V
575V series:
–
Frame A D = Pr. 06-00 + 100.0V
Frame E and above = Pr. 06-00 + 120.0V
690V series:
–
Frame A D = Pr. 06-00 + 100.0V
Frame E and above = Pr. 06-00 + 100.0V
500ms
Yes
Improve power supply condition.
Check if the power specification matches the drive.
Adjust voltage to the power range of the drive.
Cycle the power after checking the power. If LvS error still exists, return to the
factory for repair.
Check the power system.
Increase the capacity of power equipment.
Install DC reactor(s).
Fault Name
Phase loss protection
Phase loss of power input
(OrP)
Action and Reset
DC BUS is lower than Pr. 07-00, and DC BUS ripple is higher than Pr. 06-52
N/A
Pr. 06-53
Manual reset
Immediately reset when DCBUS is higher than Pr. 07-00
Yes
Correctly install the wiring of the main circuit power.
Choose the model whose power matches the voltage.
If the main circuit power works normally, verify the main circuit.
Cycle the power after checking the power, if OrP error still exists, return to the
factory for repair.
Tighten the terminal screws according to the torque described in the user
manual.
Wire correctly.
Replace the cut off cable.
Verify the setting value for Pr. 06-50 Time for Input Phase Loss Detection and
Pr. 06-52 Ripple of Input Phase Loss
Check the power three-phase status.
