Servo error
(c) If another error occurs after an error code has been stored, the existing
error code is overwritten, deleting it.
However, it is possible to check the history of error occurrence by using a
peripheral device started up with the GSV13PE/GSV22PE software.
(d) Error detection flags and error codes are latched until the error code reset
signal (M1807+20n) or servo error reset signal (M1808+20n) comes ON.
POINTS
(1) When some servo errors occur, the same error code will be stored again
even if the servo error reset signal (M1806+20n: ON) is issued.
(2) When a servo error occurs, reset the servo error after first eliminating the
error cause at the servo side.
