Connecting Multiple Drives

Multiple drives may be connected together. A terminating resistor must be enabled at the start
and end of the network. Set SW2 switch 1 to "on" to enable the terminating resistor. SW2 is
found just above the upper row of control terminals and consists of two switches. The switch
towards the top (labeled "1") controls the terminating resistor. The following diagram illustrates
the connection between multiple drives for RS-485 (half duplex) and RS-422 (full duplex).

Note: The shielded wire should be connected to the drive's ground terminal.
