6 Communications Specifications
* 1. The baud rate is 4 Mbps for MECHATROLINK-I, and 10 Mbps for
MECHATROLINK-II.
* 2. 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.
* 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 controller, baud rate, or communica-
tions cycle. For details, refer to the manuals of your controller.
Communications cycle: Integral multiple of transmission cycles
(depending on the host controller settings).
Example: If the host controller is an MP2300
• For MECHATROLINK-II (32-byte transmission,
2-ms communications cycle): 21 stations max. (21 slaves can be
set, but then the maximum number of connectable Inverters will
be 16.)
• For MECHATROLINK-II (32-byte transmission,
1-ms communications cycle): 9 stations max.
• For MECHATROLINK-II (17-byte transmission,
1-ms communications cycle): 15 stations max.
• For MECHATROLINK-I: 14 stations max.
* 5. At the maximum transmission distance of 50 m, the maximum number
of slaves is 15.
