Network Termination
The two ends of the MEMOBUS/Modbus network line have to be terminated. The drive has a built in terminating resistance
that can be enabled or disabled using DIP switch S2. If a drive is located at the end of a network line, enable the terminating
resistance by setting DIP switch S2 to the ON position. Disable the terminating resistance on all slaves that are not located at
the network line end.
