4 POSITIONING DEDICATED SIGNALS
(4) Complete signal OFF command (M4804+20n)
(a) This command is used to turn off the positioning start complete signal
(M4000+20n) and positioning complete signal (M4001+20n).

POINT
Do not turn the complete signal OFF command on with a PLS instruction.
If it is turned on with a PLS instruction, it cannot be turned off the positioning start
complete signal (M4000+20n) and the positioning complete signal (M4001+20n).
(5) Error reset command (M4807+20n) ..................... Command signal
(a) This command is used to clear the minor/major error code storage register
of an axis for which the error detection signal has turn on (M4007+20n :
ON), and reset the error detection signal (M4007+20n).
(b) The following processing is executed when the error reset command turns
on.
• If the virtual servomotor and output module are normal, the minor/major
error code storage registers are cleared and the error detection signal
(M4007+20n) is reset.
• If the virtual servomotor and output module error has not been canceled,
the error code is again stored in the minor/major error code storage
register.
In this case, the error detection signal (M4007+20n) remains on.
(6) External stop input disable at start command (M4809+20n)
This command is used to set the external stop signal input valid or invalid.
• ON......... External stop input is set as invalid, and even axes which stop input is
turning on can be started.
• OFF .......External stop input is set as valid, and axes which stop input is
turning on cannot be started.
POINT
When it stops an axis with the external stop input after it starts by turning on the
external stop input disable at command (M4809+20n), switch the external stop
input from OFF ON (If the external stop input is turning on at the starting, switch
it from ON OFF ON).
