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 DSPL or
ENTER redisplays the constant No.

Description
Flashes: Attempt made to execute
READ while Constant Read Selection
Prohibit (n77) is set to 0.
Flashes: The constant could not be
read properly for READ operation. Or,
a main circuit low voltage is detected
during READ operation.
Flashes: A checksum error occurred in
the constant data stored in the Digital
Operator.
Flashes: The password for the con-
nected Inverter and that for the con-
stant data stored in the Digital
Operator disagree. Example: Writing
(COPY) from VS mini to VS-606V7
Flashes: No constant data stored in
the Digital Operator.
Flashes: Attempt made to execute
writing (COPY) or VERIFY between
different voltage classes or different
control modes.
Flashes: A main circuit low voltage
was detected during writing (COPY)
operation.
Lit: A checksum error occurred in the
constant data stored in the Inverter.
Flashes: Attempt made to execute
COPY or VERIFY between different
Inverters of different capacities.
Flashes: A communications error oc-
curred between the Inverter and the
Digital Operator.
Corrective Action
Confirm the necessity to execute
READ, then set Constant Read Selec-
tion Prohibit (n77) to 1 to execute
READ.
Confirm that the main circuit power
supply voltage is correct, then re-exe-
cute READ.
The constants stored in the Digital Op-
erator cannot be used.
Re-execute READ to store the con-
stants in the Digital Operator.
Check if the Inverters are the same
product series.
Execute READ.
Check each voltage class and control
mode.
Confirm that the main circuit power
supply voltage is correct, then re-exe-
cute writing (COPY).
Initialize the constants. If an error oc-
curs again, replace the Inverter due to
a failure of constant memory element
(EEPROM) in the Inverter.
Press ENTER to continue the execu-
tion of COPY or VERIFY. Press STOP
to interrupt the execution of COPY or
VERIFY.
Check the connection between the In-
verter and Digital Operator.
If a communications error occurs dur-
ing the READ operation or writing
(COPY) operation, always re-execute
the READ or COPY.
