Name of alarm Indication Description
Power line frequency
synchronization error
FrE
The detected source frequency has gone out of the range from 46 to 54 Hz or 56
to 64 Hz (immediately after power-on only) or it has exceeded the "basic
frequency (50/60 Hz) ±15%," or the standard deviation of the source frequency
multiplied by three (3
σ
) has exceeded 5 Hz (at the time of a run command
input).
Note that no alarm is issued when F02 (Restart Mode After Momentary Power
Failure) = 1.
Charging circuit error PbF
This function is enabled only when 73ANS (73 answerback) is selected using
the X1 function.
There has been no X1 input (that is, the output signals of charging circuit has
not output or the magnetic contactor for bypassing the charging circuit has not
closed) within 0.5 sec after the charging circuit control output
73A signal was
issued. To reset the alarm stop state, change the X1 function selection or restart
the converter.
Heat sink overheat OH1
Due to a stop of the cooling fan(s), etc., the temperature around the heat sink
that cools down semiconductor elements of the main circuit has risen.
External alarm OH2 The converter has stopped due to the entry of the external signal THR .
Overheat inside
converter
OH3
The temperature around the control printed circuit board has risen due to poor
ventilation inside the converter.
Converter overload OLU
The AC source current has exceeded the inverse-time characteristic overload
level of the converter shown in Figure 7.1-1.
For MD mode: 150% / 60 s
For LD mode: 110% / 60 s
Memory error Er1 A data writing error or other errors in the memory have occurred.
Keypad
communications error
Er2 A keypad transmission error has occurred.
CPU error Er3 A CPU error has occurred.
Network device error Er4
When the converter was driven through the communications link such as
T-Link, SX bus or CC-Link, a transmission error has occurred due to noise.
This alarm is caused by a PLC failure, wire break in the communication path, or
failure of options.
Operation procedure
error
Er6 Two or more network option boards (T-Link, SX Bus, or CC-Link) are mounted.
A/D converter error Er8 An error has occurred in the A/D converter circuit.
Optical network error Erb
A transmission error has occurred in the communications link between
converters using high-speed serial cards (SI or SIR option).
