Errors when Using the Digital Operator Copy Function
The errors that can occur when using the copy function from the Digital Operator are given in the following
table. An error code will be displayed on the Digital Operator. If a Digital Operator key is pressed when an
error code is being displayed, the display will be cleared and 03-01 will be displayed. The error contact output
and alarm output will not function.
Saturation
Motor core satura-
tion error (detected
only for rotational
autotuning)
*
The results of autotuning has exceeded
the setting range for a user constant so a
temporary setting was made for the
motor core saturation coefficient.
• Check the input data.
• Check motor wiring.
• If the motor is connected to the
machine, disconnect it.
Rated FLA Alm
Rated current setting
alarm
*
The rated current is set high.
Check the input data (particularly the
motor output current and motor rated
current).

READ
IMPOSSIBLE
Digital Operator
write-protected
o3-01 was set to 1 to write a constant
when the Digital Operator was write-
protected (o3-02 = 0).
Set o3-02 to 1 to enable writing con-
stants with the Digital Operator.
IFE
READ DATA
ERROR
Illegal read data
The read data length does not agree.
Repeat the read.
Check the Digital Operator cable.
Replace the Digital Operator.
The write data is incorrect.
RDE
DATA ERROR
Illegal write status
An attempted write of a constant to
EEPROM on the Digital Writer failed.
A low Inverter voltage has been
detected.
Repeat the read.
Replace the Digital Operator.
Copy
CPE
ID UNMATCH
ID not matched
The Inverter product code or software
number is different.
Use the copy function for the same
product code and software number.
VAE
INV. KVA
UNMATCH
Inverter capacity
matched
The capacity of the Inverter being
copied and the capacity in the Digital
Operator are different.
Use the copy function for the same
Inverter capacity.
CRE
CONTROL
UNMATCH
Control method
matched
The control method of the Inverter
being copied and the control method
in the Digital Operator are different.
Use the copy function for the same
control method.
CYE
COPY ERROR
Verify error
The constant written to the Inverter
was compared with the constant in the
Digital Operator and they were differ-
ent.
Retry the copy.
CSE
SUM CHECK
ERROR
Checksum error
The checksum in the Inverter constant
area was compared with the checksum
in the Digital Operator constant area
and they were different.
Retry the copy.
Verify
VYE
VERIFY
ERROR
Verify error
The Digital Operator and Inverter set-
tings do not agree.
Retry the copy and verify again.
