POINTS
(1) When using the sequence extension base and bus connection type GOT, select the A168B as the
sequence extension base. When not using the sequence extension base, you can connect the bus
connection type GOT directly to the extension connector of the main base unit.
(2) When using a teaching unit A31TU-E with a dead-man switch, a dedicated connecting cable
A31TUCBL03M is required between the CPU unit and A31TU-E connector. If the A31TU-E is
connected directly to the RS422 connector of the CPU without using a dedicated cable, the
A31TU-E will not operate at all. After disconnecting the A31TU-E, attach a short-circuit connector
A31SHORTCON for A31TUCBL.
(3) In a motion module, a sequence A1S I/O modules can also be installed.
*2 The A173UHCPU can use four channels of the SSCNET. When using the SSCNET card/board
(A30CD-PCF/A30BD-PCF), connect it to the SSCNET4 and the servo amplifiers to the SSCNET1
to 3.
In this case, up to 24 axes of servo amplifiers can be connected.
*3 TRA tracking enable can use any one point.
