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
comp	Comparing function
prot	Memory protecting function
clr	Memory initializing function
a，b，c，in，	Name of objective	a (memory A), b(memory B), c(memory C)
sys，sup	memory	in(inverter's memory), sys(all memories), sup(Special data)
＿ ＿-＿ ＿	Copying from ＿ to＿
＿ ＿=＿ ＿	Comparing data of ＿ with that of ＿
end	End of copying or comparing
0ff，0n	On/Off status of memory protection function or memory initializing function
	(ON: to execute, OFF: not to execute)
f___	Communication number of parameter
00 - ff	Result of check sum (hexadecimal number)

■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	E2PROM 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	When memory A (or B or C) is selected as the source of copying operation or when it is selected
erRb	with comparison and protection functions with no data in either case in the memory (including the
erRc	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.
