[2] Virtual I/O Port
Virtual I/O ports are provided so that the controller can notify internal information. They are
used to warn a low power-supply voltage, notify errors, etc. Use these ports as necessary.
TT/TTA Virtual Input Ports (Internal Flags)
Port No. Function
7000 Always OFF
7001 Always ON
7002 System-memory backup battery voltage low warning (Note TTA is for system reservation)
7003 System-memory backup battery voltage error (Note TTA is for system reservation)
7004 Reserved by the system = Use is prohibited
7005 Reserved by the system = Use is prohibited
7006 Critical system error = A message level error is present.
7007 Critical system error = An operation-cancellation level error is present.
7008 Critical system error = A cold-start level error is present.
7009 Reserved by the system = Use is prohibited
7010 A cause of drive-source cutoff is present (including a condition waiting for a cutoff cancellation input).
7011 A latch signal indicating that a cause of all-operation cancellation is present.
(This latch signal is used to recognize a cause of 1-shot reset. Latch cancellation: 7300-ON)
7012 A cause of all-operation pause is present (including a condition waiting for the restart switch to be pressed).
(Effective only in the auto operation recognition mode)
7013 A cause of all-servo-axis interlock is present (cause of all-operation pause + cause of interlock input port)

TT Virtual Output Ports (Internal Flags)
Port No. Function
7300 A latch cancellation signal is output to cancel the latch signal indicating a cause of all-operation cancellation
(7011). (Unlatched only when the cause of operation cancellation is no longer present.)
(7300 is turned OFF after latch cancellation is attempted.)
7301 to 7380 (For future expansion = Use is strictly prohibited)
7381 to 7399 (Reserved by the system = Use is strictly prohibited)
