12 ERROR CODE LISTS
(2) Motion error detection flag (M2039)
The Motion error detection flag (M2039) turns on when any of the errors detected
by the Motion CPU occurs.
At error occurrence, data are set to the error devices in the following procedure.
(a) Set the error code to each axis or error devices.
(b) Turns on the error detection signal of each axis or error.
(c) Set the error information to Motion error history devices (#8640 to #8735).
(d) Turns on the Motion error detection flag (M2039) .
In the user program, reset the "Motion error detection flag (M2039)" after reading
the error history at the "Motion error detection flag (M2039)".
After that, "Motion error detection flag (M2039)" turns on again at occurrence of a
new error.
POINT
(1) Eliminate the error cause after confirming error content, and then turn OFF the
Motion error detection flag (M2039) by user side.
The self-diagnostic error information except the stop error is cleared by turning
M2039 ON to OFF.
(2) Set the clock data and clock data read request (SM801) in the user program.
(3) Error setting at servo warning occurrence
Set whether or not to output errors to the Motion error history or self-diagnostic
error at servo warning occurrence.
Set this setting in the system basic setting of system settings.
Refer to the "Q173D(S)CPU/Q172D(S)CPU Motion controller Programming
Manual (COMMON)" for details.
