9.1.6.3 Serial Output (When the ABS-RⅡ Absolute Sensor Is Used)
One of the two position signal outputs can be selected using the remote operator. When FUNC5 bit 7 on
Page 6 in Mode 2 of the remote operator is set at 0, start-stop synchronization is selected.
When bit 6 is set at 1, Manchester coding synchronization is selected. For details, refer to Func5 in "7.2.3
Parameter List". The specifications are as follows:
(1) Serial output specifications
