KPED-LE02
Over-voltage at stop
Action and Reset
DC bus is higher than 410V / 820V
Immediately act
Use Pr.04-02 to set to reset automatically or manually
Resets when DC bus is lower than 369V / 738V
Yes
Check if the input voltage is within the rated drive input voltage range, and check for
possible voltage spikes.
Check if other fault codes such as Hd2 occurs after cycling the power. If yes, return to
the factory for repair.
Verify the wiring of the control circuit and the wiring/grounding of the main circuit to
prevent interference.

Low voltage during
acceleration
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), LvA is a fault and will be recorded.
When Bit 0 = 1 (Display Lv warn and coast to stop), LvA 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.
If the DC bus low voltage of the drive is caused by the heavy door weight, increase the
acceleration time.

When Bit 0 = 0 (Display Lv fault and coast to stop), Lvd is a fault and will be recorded.
When Bit 0 = 1 (Display Lv warn and coast to stop), Lvd 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.
