Fault Name
KPED-LE02
Over-voltage during
acceleration
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
If the DC bus over-voltage occurs due to the regenerative voltage of motor inertia,
increase the acceleration time.
Check if the input voltage is within the rated drive input voltage range, and check for
possible voltage spikes.
Verify the wiring of the control circuit and the wiring/grounding of the main circuit to
prevent interference.
