4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Automatic initialization mode
[Function]
The automatic initialization mode is selected.
[Operation]
This mode is selected when automatic initialization is to be carried out with the machine end stopper method of absolute
position detection.
The initialization is started when the automatic initialization mode is selected, and the Feed axis selection signal (+Jn, -Jn)
in the direction of the machine end of the axis to be initialized is turned ON.
Note
(1) The automatic initialization mode is invalid when the absolute position encoder is not provided and when the machine
end stopper method is not selected for the absolute position detection. (During feed axis selection, "M01 OPERATION
ERROR 0024" occurs.)
(2) This mode will not start in the following cases of the machine end stopper method absolute position detection. (The
message "Start not possible" is displayed.)
- When "#0 Absolute posn set" on the [ABS. POSITION SET] screen is not set to "1".
- When "#2 Zero-P" on the [ABS. POSITION SET] screen is set incorrectly.
- When "#2055 pushf" on the [ABS. POSITION PARAMETER] screen has not been set.
- When "Z71 0005" has occurred.
Cont. Signal name
A Memory mode
[Function]
Memory mode of automatic operation is selected.
In this mode of operation, automatic operation is based on programs stored in the memory.
[Operation]
 Memory mode is selected when the "Memory mode" signal (MEM) turns ON.
 The program is started with the "Automatic operation "start" command" signal (ST).
 When the mode conflicts with any other automatic operation mode or when no automatic operation mode is selected
while automatic operation is active, the NC alarm (operation error (M01 0101)) occurs and the operation stops at the
block.
Note
(1) Even if it is not in automatic operation, any invalid mode of operation triggers the operation error.
[Related signals]
(1) Automatic operation "start" command (ST: YC10)
(2) Automatic operation "pause" command (*SP: YC11)
Cont. Signal name
A Tape mode
[Function]
TAPE mode of automatic operation is selected.
In this mode of operation, automatic operation is based on tape command (RS232C input) programs stored in NC tape.
[Operation]
 Tape mode is selected when the "Tape mode" signal (T) turns ON.
 The program is started with the "Automatic operation "start" command" signal (ST).
 When the mode conflicts with any other automatic operation mode or when no automatic operation mode is selected
while automatic operation is active, the NC alarm (operation error (M01 0101)) occurs and the operation stops at the
end of the block.
Note
(1) Even if it is not in automatic operation, any invalid mode of operation will trigger the operation error.
[Related signals]
(1) Automatic operation "start" command (ST: YC10)
(2) Automatic operation "pause" command (*SP: YC11)
