4 Explanation of Interface Signals

4.1 PLC Input Signals (Bit Type: X***)

Spindle 2nd in-position

This signal informs that the spindle has been positioned within the specified range in accordance with the spindle

orientation command. The information is sent earlier than the "Spindle in-position" signal. Since orientation completion can

be predicted using this signal, it is possible to eliminate the sequence delay time, etc. for tool changes and other such

operations, thereby achieving a shorter tact time.

Orientation is started by the "Spindle orientation command" (ORC), and this signal turns ON when the difference between

the orientation position and the feedback position is within the range of the 2nd in-position width.

 The range of in-position can be set by the spindle specification parameter "#3132 ori_inp2".

 The in-position signal is turned OFF when the "Spindle orientation command" (ORC) is turned OFF.

(1) When the spindle orientation command is given, orientation starts regardless of the status of the "Spindle forward run

start" (SRN) or "Spindle reverse run start" (SRI).

(2) This signal is not available when an analog connection is used.

(3) The spindle is in the servo-locked state during the spindle orientation command. However, if the spindle is rotated by

an external force, the in-position signal may turn OFF.
