◆ Terminal A3 Analog/PTC Input Selection
Terminal A3 can be configured either as multi-function analog input or as PTC input for motor thermal overload
protection. Use switch S4 to select the input function as described in Table 3.14. Refer to Switches and Jumpers on the
Terminal Board on page 85 for locating switch S4.
Table 3.14 DIP Switch S4 Settings
◆ 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 85 for locating jumper S5.

Table 3.16 Parameter H4-07, H4-08 Details
◆ MEMOBUS/Modbus Termination
This drive is equipped with a built in termination resistor for the RS-422/RS-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 85 for locating switch S2.
