KPED-LE02
Low voltage during
constant speed
Action and Reset
DC bus voltage level (Pr.04-30)
Immediately act
Use Pr.04-01 or Pr.04-02 to set to reset automatically or manually
230 models Resets when DC bus voltage is higher than Pr.04-30 + 30 V
for 50 ms
460 models
Pr.04-01 (Default: 0)
When Bit 0 = 0 (Display Lv fault and coast to stop), Lvn is a fault and will be recorded.
When Bit 0 = 1 (Display Lv warn and coast to stop), Lvn is a warning and will not be
recorded.
Adjust the input voltage to the power range of the drive
Reduce the load.
Increase the drive capacity.

Fault Name
KPED-LE02
Low voltage at stop
Action and Reset
Pr.04-30 (Default = depending on the model)
Immediately acts when DC bus voltage is lower than Pr.04-30
Auto reset
230 models Resets when DC bus voltage is higher than Pr.04-30 + 30 V
for 50 ms
460 models
No
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 still exists, return to the factory for
repair.
Check the power system.
Increase the capacity of power equipment.
Install DC reactor(s).
DC bus voltage is lower than Pr.04-30 (low
voltage level) setting value during constant
speed
Corrective Actions
1. DC bus voltage is lower than Pr.04-30 (low
voltage level) setting value at stop
2. Hardware failure in voltage detection
