5. Indications on display
Messages appearing on the display are classified into three, namely, title indications, malfunction
indications and alarm indications.
■
Title indications (function indications): Indicated by LED lamps
LED indication
Description
init
In initialization
chc
In checking of initial communication with inverter
copy
Copying function

■
Malfunction indications: Indicated by blinking LED
LED indication
Description
raMe
RAM built in the parameter writer is abnormal.
If the same indication appears after resetting the parameter writer, it needs to repair.
roMe
ROM built in the parameter writer is abnormal.
If the same indication appears after resetting the parameter writer, it needs to repair.
eePe
E
2
PROM built in the parameter writer is abnormal.
If the same indication appears after writing (copying) data again, it needs to repair.
cpUe
CPU of the parameter writer is abnormal.
If the same indication appears after resetting the parameter writer, it needs to repair.
coMe
Abnormal communication
When communication is normally operated after the indication, the alarm mode (indication)
is automatically cancelled. If the same indication appears after checking connection of the
inverter's serial communication cable and resetting the parameter writer, the unit needs to repair.
■
Alarm indications (warning indications): Indicated by blinking LED
LED indication
Description
prot
The target memory to copy data or to initialize is write protected. You cannot copy data to the
memory or initialize that memory.
deVe
The type of device is different (different in type or capacity of inverter).
If you press the ENT key when you are copying between two inverters of different capacities, the
system executes a copying operation forcefully but the system ends the operation if you press the
ESC key. If you set “
sup
” (system area parameters) to “
off
” (protection disabled) with
“
prot
(memory protection)” function, you cannot write data even if you press the ENT key.
If you have written data forcefully between two inverters with different capacities, we suggest you
execute a parameter initialization for each level of inverter capacity. See the inverter instruction
manual on how to initialize parameters.
erRa
erRb
erRc
When memory A (or B or C) is selected as the source of copying operation or when it is selected
with comparison and protection functions with no data in either case in the memory (including the
case when power was turned off during the previous copying operation), or when a check sum
error occurred, this indication appears.
Write data other than zero to the memory.
f___
Indicates the communication number of the parameter whose setting value is different.
clr
If you press the “STOP key” while an alarm message is displayed, “
clr
” flickers for one
second. If you press the “STOP key” again when “
clr
” flickers, the parameter writer will be
reset.
