(Note-1) : You can use these cables when the tracking enable signal is not used.
When the tracking enable signal is used, fabricate the cable on the customer side.
(Note-2) : Serial absolute synchronous encoder (MR-HENC) for Q173CPU(N)/Q172CPU(N)
can also be used. Refer to the "Q173CPU(N)/Q172CPU(N) Motion controller
User's Manual (IB-0300040)" for details of MR-HENC.
