◆ Terminal A2 Input Signal Selection
Terminal A2 can be used to input either a voltage or a current signal. Select the signal type using switch S1 as explained
in Table 3. 12. Set parameter H3-09 accordingly as shown in Table 3.1 3. Refer to Switches and Jumpers on the Terminal
Board on page 76 for locating switch S1.
Note: If terminals A1 and A2 are both set for frequency bias (H3-02 = 0 and H3-10 = 0), both input values will be combined to create
the frequency reference.

Table 3.13 Parameter H3-09 Details
◆ 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 76 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 3.1 5. 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 76 for locating jumper S5.
