1. SUMMARY
1.6 SSCNET
cables
Connect the position board and servo amplifiers, or servo amplifier and servo amplifier by SSCNET
cable.
When using MR-MC210/MR-MC240, the SSCNET
cable for connecting servo amplifiers can be used for one
line only. When using MR-MC211/MR-MC241, the SSCNET
cable for connecting servo amplifiers can be
used for up to two lines (use 1CH and 2CH). Up to 32 servo amplifiers can be connected.
