St.320
Synchronous encoder axis
setting valid flag
This flag turns ON when the setting
of the synchronous encoder axis is
valid.
ON : Setting valid
OFF : Setting invalid
At power ON 10n
St.321
Synchronous encoder axis
connecting valid flag
This flag turns ON when the
synchronous encoder axis
connection is valid.
ON : Connection valid
OFF : Connection invalid
10n
St.322
Synchronous encoder axis
counter enable flag
This flag turns ON when input from
the synchronous encoder is
enabled.
ON : counter enable
OFF : counter disable
10n
St.323
Synchronous encoder axis
current value setting
request flag This flag turns ON when the
current value of synchronous
encoder axis is not set.
ON : Current value setting
request
OFF : Current value setting
not requested

St.324
Synchronous encoder axis
error detection flag
This flag turns ON when an error
occurs for the synchronous
encoder axis.
ON : Error occurred
OFF : No error
10n
St.325
Synchronous encoder axis
control complete flag
This flag turns ON at the
completion of synchronous
encoder axis control.
ON : Control completed
OFF : Control not completed

(1) [St.320] Synchronous encoder axis setting valid flag (10n)
At Multiple CPU system power supply ON, this flag turns ON when the setting of
the synchronous encoder axis is valid.
It is turned OFF when the setting is invalid.
(2) [St.321] Synchronous encoder axis connecting valid flag
(10n)
At Multiple CPU system's power supply ON, this flag turns ON when the
synchronous encoder connection is valid. This flag turns OFF when the
connection is invalid.
When setting an incremental synchronous encoder, this flag turns ON
simultaneously the Multiple CPU system power supply turns ON regardless of
the actual encoder connection.
(3) [St.322] Synchronous encoder axis counter enable flag
(10n)
This flag turns ON when input from the synchronous encoder is enabled.
If the counter disable control is executed, it is turned OFF, and input from the
synchronous encoder becomes invalid.
If the counter enable control is executed, it is turned ON, and input from the
synchronous encoder becomes valid.
Just after the synchronous encoder is valid to connect, the status is ON (enable).
