[St.320] Synchronous encoder axis setting valid flag (R: M38640+16n/Q: M10440+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.
[St.321] Synchronous encoder axis connecting valid flag (R: M38641+16n/Q:
M10441+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.
[St.322] Synchronous encoder axis counter enable flag (R: M38642+16n/Q:
M10442+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).
Storage details
This flag turns ON when the
setting of the synchronous
encoder axis is valid.
This flag turns ON when the
synchronous encoder axis
connection is valid.
This flag turns ON when input
from the synchronous encoder is
enabled.
This flag turns ON when the
current value of synchronous
encoder axis is not set.
This flag turns ON when an error
occurs for the synchronous
encoder axis.
This flag turns ON at the
completion of synchronous
encoder axis control.
