Model
<1> For MECHATROLINK-I, a cycle is 2 ms. For MECHATROLINK-II, a cycle is 1 ms to 8 ms for a 32-byte data
transmission, and 500 μs to 8 ms for a 17-byte data transmission.
<2> At the maximum transmission distance of 50 m, the maximum number of stations is 15.
<3> For MECHATROLINK-I, only a 17-byte data transmission can be selected.
<4> The maximum number of connectable stations changes depending on the types and settings of the host master,
baud rate, or communications cycle. For details, refer to the manuals of your master.
Communications cycle: Integral multiple of transmission cycles (depending on the host master settings).
Example: If the host master is an MP2300
x For MECHATROLINK-II (32-byte transmission, 2.0 ms communications cycle: 21 stations max. (21 stations
can be set, but then the maximum number of connectable drives will be 16.)
x For MECHATROLINK-II (32-byte transmission, 1.0 ms communications cycle: 9 stations max.
x For MECHATROLINK-II (17-byte transmission, 1.0 ms communications cycle: 15 stations max.
x For MECHATROLINK-I: 14 stations max.
