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.
