4 Explanation of Interface Signals
4.3 PLC Output Signals (Bit Type: Y***)
Cont. Signal name
A Superimposition control request n-th axis
[Function]
Whether to start or cancel superimposition control is selected with a signal corresponding to the superimposed axis.
1 -> 0 (falling edge) Superimposition control cancel
0 -> 1 (rising edge) Superimposition control start
[Operation]
Superimposition control is started and canceled at the rising edge (OFF to ON) or at the falling edge (ON to OFF) of the
PLC signal (PILE1 to 8) corresponding to the superimposed axis.
Thus, to perform the superimposition control again when the superimposition control is canceled due to a factor other than
turning OFF the PLC signal such as an emergency stop, turn OFF the PLC signal and then turn it ON again.
The reference axis corresponding to each superimposed axis set with the parameter "#2089 bsax_pl".
The movement direction of the superimposed axis in respect to the movement of the reference axis is determined by the
value set for parameter "#2143 polar".
0: moves in the same direction as the reference axis
1: moves in the opposite direction of the reference axis
[Caution]
(1) This signal is ignored if "0" is set to the parameter "#1280 ext16/bit7".
(2) Make sure to command a timing synchronization for the superimposed axis and the reference axis in the blocks
before and after the command of this signal.

Cont. Signal name
A NC axis control selection n-th axis
[Function]
This signal is used to select the control method of the NC axes which can be controlled by PLC.
0: PLC control
1: NC control
[Operation]
When this signal is ON, the axis is controlled with a machining program. (The axis is handled as an NC axis.)
When this signal is OFF, the axis is controlled with the PLC axis indexing interfaces. (The axis is handled as a PLC axis.)
The correspondence between the axis Nos. and the device Nos. is as follows.
