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