u MEMOBUS/Modbus Termination
This drive is equipped with a built-in termination resistor for the RS-422/RS-485 communication connector. DIP switch S2
enables or disabled the termination resistor as shown in Table 3.16 . The OFF position is the default. The termination resistor
should be placed to the ON position when the drive is the last in a series of slave drives. Refer to Switches and Jumpers on
the Terminal Board on page 104 to locate switch S2.
