4 Explanation of Interface Signals
4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Spindle OFF mode
[Function]
This function is used to check the program by moving the machine without rotating the spindle.
[Operation]
<Synchronized tapping mode>
By turning on the spindle OFF mode, the spindle does not turn ON or rotate.
Even if the spindle OFF mode is changed during the synchronized tapping mode, the operation does not change until the
synchronized tapping mode is turned OFF. It is recommended to turn ON this signal from the beginning of operation.
<Asynchronous tapping mode>
 During synchronous (every revolution) feed
In addition to M03, M04 processing and dry run signal, turn ON the spindle OFF mode. The program proceeds when the
signal is turned ON.
 During asynchronous feed (every minute) feed
The program proceeds even if the spindle OFF mode is not turned ON.
<Thread cutting>
When the parameter "#1279 ext15/bit4" (Dry run OFF during thread cutting) is set to "1", the dry run is disabled for thread
cutting. However, when the "Spindle OFF mode" signal is ON, dry run is enabled regardless of the parameter setting, and
the status of dry run is determined by the "Dry run" signal.

Cont. Signal name
A Longitudinal hole drilling axis selection
[Function]
This signal is used to specify the hole drilling axis for the longitudinal hole drilling fixed cycle (G87, G88, G88.1, and G89).
[Operation]
When this signal is OFF (0), the X axis becomes the hole drilling axis.
When this signal is ON (1), the Y axis becomes the hole drilling axis.
When a hole edge chamfering cycle is executed while this signal is ON, the program error (P188) occurs.
Cont. Signal name
A Tap retract possible state cancel
[Function]
Turning ON this signal allows to move the axis, both automatically and manually, without tap retract.
This signal is used when it is judged that the spindle rotation due to tap retract is dangerous, such as when the tap is
damaged.
[Operation]
Turning this signal ON turns OFF the "Tap retract possible" signal (TRVE).

(1) Tap retract (TRV: YC5C)
(2) Tap retract possible (TRVE: XCA5)
