4 Explanation of Interface Signals
4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Door open II
[Function]
This signal stops all axes and shuts OFF the contactor.
[Operation]
The NC carries out the following operations when the "Door open II" signal turns ON.
 A deceleration stop is carried out for all axes (servo axes and spindles). (Axis interlock)
 After all axes are stopped, the contactor of each drive unit is shut OFF. The "Servo ready completion" signal (SA) does
not turn OFF.
 The "Door open enable" signal turns ON.
The NC carries out the following operations when the "Door open II" signal turns OFF.
 A ready ON and servo ON state occurs for all axes.
 The "Door open enable" signal turns OFF.
[Caution]
<Handling of the PLC axis>
For the PLC axis, stop it at the PLC and then output a door open signal to the NC. If a door open signal is input without
stopping the PLC axis, the axis stops with a dynamic brake method due to the ready OFF state. The remaining distance
will be held in the R register being used in the PLC axis control.
<Handling of the analog spindle>
When an analog spindle is connected, it is not possible to confirm that the spindle has completely stopped with the NC.
Thus, confirm that the spindle has completely stopped using the PLC before opening the door.
Since the spindle may resume rotation immediately after the door is closed, for safety, turn the forward run and reverse
run signals OFF when the door is opened.
<Opening the door during ATC operation>
To open the door while ATC is operating, apply an interlock with the user PLC.

Cont. Signal name
Door open signal input (spindle speed
A
monitor)
[Function]
This signal informs the door open or close state to the spindle drive unit with the spindle speed monitor function.
[Operation]
When the door is in the open state, turn ON (1) this signal.
The compatibility check of this signal and the door close signal connected with the spindle drive unit is performed in the
spindle drive unit.
If those signals are not compatible for continuous 3 seconds, the servo alarm (S01 5D) occurs.
