4 Explanation of Interface Signals
4.2 PLC Input Signals (Data Type: R***)
Cont. Signal name
A Servo ready completion
[Function]
This signal indicates that the servo system is ready for normal operation. In other words, the servo system (position
control) is not working when this signal is OFF.
[Operation]
The signal turns ON when:
 The servo system diagnosis is normally completed after the power is turned ON.
 The servo alarm, which had occurred, has been released by the "Master reset" (MRST).
 The emergency stop has been released.
 The "Ready OFF" (RDF) is turned OFF.
The signal turns OFF when:
 The "Controller ready completion" (MA) is turned OFF.
 A servo alarm has occurred.
 Emergency stop is issued.
 The "Ready OFF" (RDF) is turned ON.
[Caution]
(1) With the "Servo OFF" (*SVF), the "Servo ready completion" (SA) will not turn OFF unless there is another condition to
turn OFF the SA.
(2) In an emergency stop status, all I/O output points turn OFF.
[Related signals]
(1) Master reset (MRST: AUXCM1/bit3)
(2) Ready OFF (RDF: AUXCM1/bit6)
(3) Controller ready completion (MA: AUXST1/bitB)
Cont. Signal name
A Automatic set position reached
[Function]
In the automatic operation, this signal notifies that the positioning to the commanded station No. is completed. The
tolerable width which this signal is regarded as ON is as same as that of the "Set position reached" (JST).
[Operation]
The signal turns ON when:
 The positioning to the designated station No. is completed in the automatic operation mode.
The signal actually turns ON when the tool enters the tolerable width before the positioning is completed.
The signal turns OFF when:
 The "Operation start" signal is input in any of the operation modes.
 The tool deviates outside the tolerable width.
[Caution]
(1) This signal does not turn ON when positioning is performed to the nearest station by turning OFF the "Operation start"
signal during automatic operation.
(2) Even if the indexing of the same station No. is started when this signal is ON, this signal does not turn OFF.
(3) When the indexing of the same station number is started with the positioning to the station completed in the manual
mode, this signal turns ON. However, there is no movement.
(4) Once this signal is turned OFF, it does not turn ON even if the axis returns to the tolerable width.
(5) During the emergency stop or the servo OFF, when a tool once deviated outside the width of "Set position reached",
then returns within the area, this signal turns ON again if "#12802 aux_Cont1/bit4" is set to "OFF", and does not turn
ON if "#12802 aux_Cont1/bit4" is set to "ON".
