Description Remarks
AC fuse blown
acf
Stops the converter output if the AC fuse (R-/T-phase only) is blown.
AC overvoltage
a0u
Stops the converter output upon detection of an AC overvoltage condition.
AC undervoltage
alu
Stops the converter output upon detection of an AC undervoltage condition.
AC overcurrent
a0c
Stops the converter output if the peak value of the input current exceeds the overcurrent
level.
AC input current error
ace
Stops the converter output upon detection of the excessive deviation of the AC reactor
from the AC input.
Input phase loss
lpu
Stops the converter output upon detection of an input phase loss.
Synchronous power
frequency error
fre
After the MC for charging circuit (73) is turned on, the converter checks the power
frequency. If it detects a power frequency error, this function stops the converter output.
An error during converter running (e.g., momentary power failure) triggers no alarm.
DC fuse blown
dcf
Stops the converter output if the DC fuse (P side) is blown. 18.5 kW or above
DC overvoltage
d0u
Stops the converter output upon detection of a DC overvoltage condition.
If a power failure continues for a long time and the control power source is shut down, this
alarm is automatically reset.
200 V class series: 400 V ±3 V
400 V class series:800 V ±5 V
DC undervoltage
dlu
Stops the converter output upon detection of a DC undervoltage condition.
If a power failure continues for a long time and the control power source is shut down, this
alarm is automatically reset.

restarts at 208 V.
400 V class series: Stops at 371 V,
restarts at 417 V.
