(1) Synchronous encoder current value monitor in real mode
The synchronous encoder set in the system setting is updated for every
operation cycle in the current value storage register (D1120+10n, D1121+10n)
regardless of whether or not the synchronous encoder is set in the mechanical
program.
However, the current value after synchronous encoder axis main shaft’s
differential gear storage registers (D1126+10n, D1127+10n) is updated in only
virtual mode.
Refer to this section (4) for the synchronous encoder current value that the
external input clutch is set.

(2) Error reset of the synchronous encoder axis
The error reset command (M5440+4n) can be executed in both of the real mode
and virtual mode.
If the error reset command (M5440+4n) is turned ON when the synchronous
encoder and output module are normal, the minor error code storage register
(D1122+10n) and major error code storage register (D1123+10n) are cleared,
and the error detection signal (M4640+4n) is reset.

(3) Synchronous encoder current value change CHGA-E
The synchronous encoder current value change (CHGA-E) of the synchronous
encoder set in the system setting can be changed regardless of whether or not
the synchronous encoder is set in the mechanical program.
