8.5 List of Error Code
8.5 List of Error Code
This clause shows the list of error codes.
 of each error code and error name indicates the number of the channel in which an error occurs.
● This clause describes errors and their corrective actions in case of the I/O numbers (X/Y), buffer memory addresses, and
external input terminals for CH1.
To check the I/O numbers (X/Y) for CH2, refer to the following:
Page 32, Section 3.3.1
To check the buffer memory addresses for CH2, refer to the following:
Page 42, Section 3.4.1
● This clause describes errors and their corrective actions by using the buffer memory addresses corresponding to
Coincidence output 1.
To check the buffer memory addresses corresponding to Coincidence output 2 to 8, refer to the following:
Page 42, Section 3.4.1
*2 The linear counter function stops counting pulses.
*3 The operation is performed normally unless an error occurs.
*4 The ring counter does not start counting pulses.
*7 All operations except the error handling are stopped. Yet dedicated instructions are processed on the condition that the
error does not affect the system (in case its error code (last 3 digits) is the numbers other than 800 to 859).
The signal output to the coincidence output 1 to 8 terminals (EQU1 to EQU8) or to the general output 1 to 8 terminals
(OUT1 to OUT8) is stopped.
Also, the updating of EQU1 to EQU8 terminal status (Un\G951), OUT1 to OUT8 terminal status (Un\G952), or CH1
External input status (Un\G1450) is stopped.

CH Overflow/
underflow error
With the linear counter function being
selected, the value outside the range of
-2147483648 to 2147483647 is stored
in CH1 Present value (Un\G1050,
Un\G1051).

CH Ring counter
upper/lower limit
value setting error
With the ring counter function being
selected, the value set to CH1 Ring
counter upper limit value (Un\G1012,
Un\G1013) is smaller than the one set
to CH1 Ring counter lower limit value
(Un\G1010, Un\G1011).

Set the values that satisfy the following formula:
CH1 Ring counter lower limit value (Un\G1010,
Un\G1011)  CH1 Ring counter upper limit value
(Un\G1012, Un\G1013)
And then perform either of the following
operations:
• Turn off and on Operating condition settings
batch-change command (Y01) when
Operating condition settings batch-changed
(X01) is OFF.
• Turn off and on CH1 Count enable command
(Y06) when Operating condition settings
batch-changed (X01) is ON.
