Note: While rEd, CPy, or vFy is flashing, key input on the Digital Operator is 
disabled. While rEd, CPy and vFy are not flashing, pressing   or 
 redisplays the constant No.
Lit: Inverter capacity display selected. -
Lit: Software No. display selected. -
Lit: READ, COPY (writing), VERIFY complet-
ed.
-
Flashes: Attempt made to execute READ 
while Constant Read Selection Pro-
hibit (n177) is set to 0.
Confirm the necessity to execute READ, then 
set Constant Read Selection Prohibit (n177) to 
1 to execute READ.
Flashes: The constant could not be read prop-
erly for READ operation. Or, a main 
circuit low voltage is detected during 
READ operation.
Confirm that the main circuit power supply 
voltage is correct, then re-execute READ.
Flashes: A checksum error occurred in the 
constant data stored in the Digital 
Operator.
The constants stored in the Digital Operator 
cannot be used.
Re-execute READ to store the constans in the 
Digital Operator.
Flashes: The password for the connected In-
verter and that for the constant data 
stored in the Digital Operator dis-
agree. 
Example: Writing (COPY) from VS-606V7 to 
VS mini J7
Check if the Inverters are the same product 
series.
Flashes: No constant data stored in the Digital 
Operator.
Execute READ.
Flashes: Attempt made to execute writing 
(COPY) or VERIFY between different 
voltage classes or different control 
modes.
Check each voltage class and control mode.
Flashes: A main circuit low voltage was de-
tected during writing (COPY) opera-
tion.
Confirm that the main circuit power supply 
voltage is correct, then re-execute writing 
(COPY).
Lit: A checksum error occurred in the constant 
data stored in the Inverter.
Initialize the constants. If an error occurs 
again, replace the Inverter due to a failure of 
constant memory element (EEPROM) in the 
Inverter.
Flashes: Attempt made to execute COPY or 
VERIFY between different Inverters 
or different capacities.
Press   to continue the execution of 
COPY or VERIFY. Press   to interrupt 
the execution of COPY or VERIFY.
Flashes: A communications error occurred be-
tween the Inverter and the Digital Op-
erator.
Check the connection between the Inverter 
and Digital Operator.
If a communications error occurs during the 
READ operation or writing (COPY) operation, 
always re-execute the READ or COPY.
