3-2-4 Parameter Copy or Verify Errors
•
The following description provides information on errors that may result while the parameter set val-
ues are read, copied, or verified, and the remedies to be taken. The display flashes while displaying
these errors.
Display Name Probable cause Remedy
pre Protection error An attempt was made to read the
parameter set values while n177
for parameter read-prohibit
selection was set to 0. Set n177 to 1 and retry after
rechecking the necessity of
reading the parameter set values.
rde Read error The parameter set values were
not read correctly or a main-circuit
low voltage was detected while
the parameter set values were
read. Retry after checking that the
voltage of the main circuit is
normal.
cse Checksum error A checksum error resulted in the
parameter set values in the
EEPROM of the Digital Operator. Read the parameter set values
again and store them in the
EEPROM.
nde No data error There are no parameter set values
stored in the EEPROM of the
Digital Operator. Read the parameter set values
and store them in the EEPROM.
cpe Copy error An attempt was made to copy or
verify the parameter set values
while the Inverters are different to
each other in voltage or control
mode. Check that the Inverters are the
same in voltage and control mode.
If either of them is different, no
parameter set values can be
either copied or verified.
If the Inverters are different only in
control mode, retry after changing
the mode of the Inverter to which
the parameter set values are to be
written.
cye Copy voltage error Main-circuit low voltage is
detected while the Inverter was
copying the parameter set values. Retry after checking that the
voltage of the main circuit is
normal.
uae Capacity error An attempt was made to verify the
parameter set values while the
Inverters were different to each
other in capacity. To continue verifying the
parameter set values, press the
Enter Key.
To cancel the operation, press the
STOP/RESET Key.
ife Communications error A communications error resulted
between the Inverter and Digital
Operator. Retry after checking the
connection between the Inverter
and Digital Operator.
