detector interface unit 1
(SDUl 1
Separate type detector interfa~ unit 2
(SDUZ)
The SDU is connected to the CNC control unit via optical cable of “FANUC serial servo
bus (FSSB)“. Another units like servo amplifiers are also connected to the FSSB. In
above figure, the SDU is connected as the last slave of the FSSB. Another
configuration is also possible, that is the SDU can be inserted between the CNC control
unit and the servo amplifier or between two servo amplifiers.
The signal from the separate type detector of the axis #l is usually connected to JFI 01.
In the same manner, signals corresponding to the axis ##2 - #8 are connected to JFIOZ
- JF108 respectively.
If necessary, the relationship between connectors JFlOl - JF108 and axes numbered
1 - 8 can be varied. In above figure, when the axes numbered 2, 4, 6, 8 have the
separate type detector, for example, the SDU2 does not need to be used by assigning
the connector JFlOl - JF104 of the SDUl to the axis 2, 4, 6, 8. Please refer to the
corresponding manual of the CNC controller for how to change the assignment.
