6 − 15
(e) Error detection signal (M4007+20n)
1) The error detection signal comes ON when a minor error or major error is
detected in a virtual servo motor or output module connected to a virtual
servo motor.
The ON/OFF status of the error detection signal is used to distinguish
whether or not an error exists.
2) When the error detection signal comes ON the corresponding error code
is then stored in the error code storage area.
• Minor error code
(Note-1)
...Stored in the minor error code storage area
(Note-2)
.
• Major error code
(Note-1)
...Stored in the major error code storage area
(Note-2)
.
The distinction as to whether the detected error is a virtual servo motor
error or an output module error can be confirmed by the contents of the
error code or by the ON/OFF status of the output module error detection
signal.
3) When the virtual servo motor or output module connected to the virtual
servo motor is in its normal status the error reset command (M4807 +
20n) is ON and the error detection signal is OFF.
REMARKS
(1) (Note-1): Refer to section 11.3 for details regarding virtual servo motor
minor/major error codes.
Refer to section 11.5 for details regarding output module
minor/major error codes.
(2) (Note-2): Refer to section 6.1.3 for details concerning the minor error code
storage area and major error code storage area.
(f) M-code output in progress signal (M4019+20n)
1) Signal indicating that M-code output is in progress.
2) This will be OFF when a stop command, cancel signal, skip signal, or
FIN signal has been input.

POINTS
(1) The M-code output in progress signal is the signal for the FIN signal wait
function.
(2) The M-code output in progress signal is only enabled when the FIN
acceleration/deceleration speed has been set in the servo program. If it
is not set the FIN signal wait function is disabled and the M-code output in
progress signal does not come ON.
