DC Bus Overvoltage
The DC bus voltage exceeded the trip point.
For 200 V class: approximately 410 V
For 400 V class: approximately 820 V (740 V when E1-01 < 400)
Cause Possible Solutions
Minor Fault
Output
(H2-01 = 10)
Surge voltage present in the
drive input power.
Install a DC reactor or an AC reactor.

thyristor
convertor and a phase
advancing capacitor operating on the same drive input power
system.
YES
The motor is short-
circuited.
Ground current has
over-charged the main
circuit capacitors via the
drive input power.
Check the motor power cable, relay terminals and motor
terminal box for short circuits.
Correct grounding shorts and turn the power back on.
YES
Noise interference causes the
drive to operate incorrectly.
Review possible solutions for handling noise interference.
Review section on handling noise interference and check
control circuit lines, main circuit lines and ground wiring.
If the magnetic contactor is identified as a source of noise,
install a surge protector to the MC coil.
YES
Set number of fault restarts (L5-01) to a value other than 0. YES
