6-3. Error Codes
2. Table of Self-diagnostic Error Codes
Notes:
1. System register 26 specifies the program execution state when an operation error occurs.
Settings:
K0: FP-M stops operation if an operation error occurs.
K1: FP-M continues operation even if an operation error occurs.
2. System register 4 specifies the operation of the FP-M when the voltage of the backup battery lowers or
when the backup battery disconnects.
Settings:
K0: The conditions above are regarded as errors.
K1: The conditions above are not regarded as errors.

error warning
by
F148 (ERR)
instruction
Description
Probably an abnormality in
the memory (EPROM) or
master memory (EEPROM).
Probably an abnormality in
the system register.
Probably a hardware
abnormality or an abnormality
caused by noise.
Probably a hardware
abnormality or an abnormality
caused by noise.
Probably an interrupt program
corresponding to the trigger is
missing.
Probably an abnormality was
detected when a high-level
or basic instruction was
executed.
The voltage of the backup
battery lowers or the connector
of the backup battery is
disconnected.
• The self-diagnostic error code specified by the
F148 (ERR)
instruction is transferred to DT9000.
• The contents of the self-diagnostic error code can be
confirmed using the programming tools.

Step to take
Program the memory
(EPROM) or master memory
(EEPROM) again and try to
operate. If the same error is
detected, try to operate with
another memory (EPROM) or
master memory (EEPROM).
Set the mode of FP-M to
PROG., initialize the system
register and set it again.
Turn OFF the power of the
FP-M and check the
surrounding noise level.
Turn OFF the power of the
FP-M and check the
surrounding noise level.
Set the mode of FP-M to PROG.
and create a program which
corresponds to the interruption.
Check the program, referring
to the error address which is
stored in special data registers
DT9018 and DT9017.
Replace the backup battery.
The operation without backup
battery can be specified by
system register 4.
