Branching a single SSCNETIII/H communication line in three separate directions
The MR-MV200 can branch a single SSCNETIII/H network line in three separate directions. This enables distribution of
the high-performance MELSERVO-J4 series servo amplifiers with flexible wiring arrangement.
● This unit is introduced just by making some changes in wiring without making any new settings.
● Longer-distance wiring becomes available by using this optical hub unit.
Reduced system restoration time by powering off only the desired servo amplifiers
When servo amplifiers are distributed using the MR-MV200, the servo amplifiers can be turned OFF independently without affecting other servo amplifiers connected to other branched lines. This leads to significant reduction in restoration time by turning OFF only the amplifiers with errors.
Topology
The optical hub unit allows more flexible topologies, such as star, line, cascade topologies, or the combination of these.
● Topology examples
Various topologies can be combined, so you can configure an ideal wiring arrangement for your application.
