3.10 MEMOBUS/Modbus Termination
The two ends of the MEMOBUS/Modbus network line must be terminated. The drive has a built-in termination resistor that
can be enabled or disabled using DIP switch S2. If a drive is a single drive on the network or is located at the end of a network
line, set DIP switch S2 to the ON position to enable the termination resistor. Disable the termination resistor on all slave drives
that are not located at the network line end.
