2-2-4 Error Messages for Copying and Verifying Parameters
The errors that can be displayed when reading, writing, or verifying parameter settings are described in
the following table along with corrective actions. All of these error displays will flash on the display.
Display Name Description Corrective action
pre
Protect error An attempt was made to read
parameter settings when the
Parameter Read Prohibit Selection
parameter (n77) was set to 0
(prohibiting reading).
Confirm that it is necessary to read
the parameter settings. If it is, change
the Parameter Read Prohibit
Selection parameter (n77) to 1
(enabling reading).
rde
Read error The parameter settings could not be
read normally or a low main circuit
voltage was detected while reading
parameter settings.
Check the main circuit voltage and
then attempt reading again.
cse
Checksum error A checksum error occurred for the
parameters recorded in the Digital
Operator.
Read the parameter settings again to
record them in the Digital Parameter.
ndt
No data error No parameters are recorded in the
Digital Operator.
Read the parameter settings to record
them in the Digital Parameter.
cpe
Copy source
error
Copying or verifying parameter
settings was attempted between
Inverters with different voltage
classes.
Check the voltage classes. (They
must both be the same to copy
parameter settings.)
cye
Voltage error
while copying
A low main circuit voltage was
detected while reading parameter
settings.
Check the main circuit voltage and
then attempt copying again.
Ure
Capacity error Verification was attempted between
Inverters of different capacities.
Press the Enter Key to continue the
comparison.
Press the STOP/RESET Key to
cancel the comparison.
ife
Communications
error
A communications error occurred
between the Inverter and Digital
Operator.
Check the connection between the
Inverter and the Digital Operator.
Correct any problems and then repeat
the operation.
