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.
200 V class series: Stops
at 185 V, restarts at 208 V.
400 V class series: Stops
at 371 V, restarts at 417 V.
Charging circuit fault
pbf
Stops the converter output upon detection of a charging
circuit fault, provided that the answerback signal from 73 is
enabled.
Condition: 73ANS
(Answerback from 73) is
assigned to terminal [X1].
Heat sink overheat
0h1
Stops the converter output upon detection of a heat sink
overheat.
External alarm
0h2
Stops the converter output upon receipt of an external signal
THR .
Condition: THR (Enable
external alarm trip) is
assigned to terminal [X1].
Converter internal
overheat
0h3
Stops the converter output upon detection of an internal
overheat of the converter.
Converter overload
0lu
Stops the converter output with the inverse-time
characteristics due to the input current.
Activate at 105%, 150% for
1 min
Memory error
er1
Stops the converter output if a data writing error or any other
memory error occurs (when the checksums of the EEPROM
and RAM do not match).
Keypad
communications error
er2
Displays “
er2
” upon detection of a wire break in initial
communication with the keypad.
This does not affect the converter operation.
CPU error
er3
Activated if a CPU error occurs.
Network device error
er4
Stops the converter output if a fatal error (including no
power supply connection) occurs in the master unit in the
network.
Applies to T-Link, SX-bus,
and CC-Link devices.
Operation procedure
error
er6
Stops the converter output upon detection of an error in the
operation procedure.
A/D converter error
er8
Stops the converter output upon detection of a failure in the
A/D converter circuit.
Optical network error
erb
Stops the converter output upon detection of an optical
cable break or a fatal error in the optical option.
IPM error
1pe
Activated when the IPM’s self-diagnosis function works due
to an overcurrent or overheat.
15 kW or below
