Precautions for Wiring MECHATROLINK-II Cables

Observe the following precautions when wiring MECHATROLINK-II cables.
Number of Connectable Stations
The number of connectable stations is determined by the settings for the transmission cycle
and number of transmission bytes. When the communications retry channel is 1, the number
of connectable stations is as follows for the combinations of transmission cycle and trans-
mission bytes.
Table 3.1 Number of Connectable Stations Determined by
Transmission
Bytes
0.5 ms
17
30
* When the transmission cycle is 0.5 ms, set the communications cycle in
multiples of 1.0 ms.
Note: 1. When the number of stations actually connected is less than the
number of connectable stations, the remaining channels, up to 7,
can be used as communications retry channels.
(Number of communications retry channels = Number of
connnectable stations - Number of actual stations connected+1)
2. When not using communications retry, the number of connnectable
stations is the number in Table 3.1 increased by one.
3. Connect a repeater for more than 16 stations.
