(6) Servo error reset command (M3208+20n)
(a) This command is used to clear the servo error code storage register of an
axis for which the servo error detection signal has turn on (M2408+20n:
ON), and reset the servo error detection signal (M2408+20n).

(b) If an error reset is executed during the temporary stop (M4003+10n) by the
temporary stop command (M4400+10n) at the automatic start or if an error
reset is executed during a block stop by M00/M01, the Motion program
operation state is reset.
The SVST instruction must be executed in the next strat. (Re-start is not
possible.)
