u Terminal AM/FM Signal Selection
The signal type for terminals AM and FM can be set to either voltage or current output using jumper S5 on the terminal board
as explained in Table 3.15 . When changing the setting of jumper S5, parameters H4-07 and H4-08 must be set accordingly.
The default selection is voltage output for both terminals. Refer to Switches and Jumpers on the Terminal Board on page
99 for locating jumper S5.

u MEMOBUS/Modbus Termination
This drive is equipped with a built-in termination resistor for the RS-422/485 communication port. DIP switch S2 enables or
disabled the termination resistor as shown in Table 3.17 . 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 99 to locate switch S2.
