3.10 Control I/O ConnectionsYASKAWA ELECTRIC SIEP C710616 27C YASKAWA AC Drive A1000 Technical Manual 79Electrical Installation3◆ Terminal A2 Input Signal SelectionTerminal A2 can be used to input either a voltage or a current signal. Select the signal type using switch S1 as explainedin Table 3.12. Set parameter H3-09 accordingly as shown in Table 3.13. Refer to Switches and Jumpers on the TerminalBoard 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 createthe frequency reference.Table 3.12 DIP Switch S1 SettingsTable 3.13 Parameter H3-09 Details◆ Terminal A3 Analog/PTC Input SelectionTerminal A3 can be configured either as multi-function analog input or as PTC input for motor thermal overloadprotection. Use switch S4 to select the input function as described in Table 3.14. Refer to Switches and Jumpers on theTerminal Board on page 76 for locating switch S4.Table 3.14 DIP Switch S4 Settings◆ Terminal AM/FM Signal SelectionThe signal type for terminals AM and FM can be set to either voltage or current output using jumper S5 on the terminalboard as explained in Table 3.15. When changing the setting of jumper S5, parameters H4-07 and H4-08 must be setaccordingly. The default selection is voltage output for both terminals. Refer to Switches and Jumpers on the TerminalBoard on page 76 for locating jumper S5.Table 3.15 Jumper S5 SettingsTable 3.16 Parameter H4-07, H4-08 DetailsSetting DescriptionV (left position) Voltage input (-10 to +10 V)I (right position) (default) Current input (4 to 20 mA or 0 to 20 mA): default settingNo. Parameter Name Description SettingRangeDefaultSettingH3-09 Terminal A2 signal level selectionSelects the signal level for terminal A2.0: 0 to 10 Vdc1: -10 to 10 Vdc2: 4 to 20 mA3: 0 to 20 mA0 to 3 2Setting DescriptionAI (lower position) (default) Analog input for the function selected in parameter H3-06PTC (upper position) PTC input.
