(10) FR-A700 series detection error
When an error occurs on FR-A700 series, the servo error detection signal
(M2408+20n) turns ON. Eliminate the error cause, reset the servo amplifier
error by turning ON servo error reset command (M3208+20n) and perform re-
start.
However, "0" is always stored in parameter error No. (#8009+20n), and
"Absolute position lost (b14)" of servo status 1 (#8010+20n).
The errors detected by FR-A700 series are shown in Table 6.2.
Refer to the instruction manual of FR-A700 series for details of the errors.
