9.1.6.2 Serial Output (When the ABS-E Absolute Encoder 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) Output specifications (9600 bps • 1 Mbps)
Table 9-2 (1) Start-stop Synchronization Output (9600 bps) Specifications
Transmission system Start-stop synchronization
Baud rate 9600 bps
Number of transfer frames 6 frames (11 bits/frame)
Transfer format See Fig. 9-7-1
Transmission error check (1 bit) even parity
Transfer time 6.9 ms (Typ.)
Transfer cycle 9.2 ms (See Fig. 9-7-3 (1).)
Incremental direction Increased at forward revolution
Table 9-2 (2) Manchester Coding Synchronization Output (1 Mbps) Specifications
Transmission system Manchester coding synchronization
Baud rate 1 Mbps
Number of transfer frames 2 frames (25 bits/frame)
Transfer format See Fig. 9-7-2.
Transmission error check (3 bits) CRC error check
Transfer time 66 µs (Typ.)
Transfer cycle 84 µs±2 µs(See Fig. 9-7-3 (2).)
Incremental direction Increase at forward revolution
Forward revolution means counterclockwise rotation as viewed from the motor shaft.
When the absolute value increases to the maximum, it returns to the minimum (0).
