■ Select Input Signals for Multi-Function Analog Input Terminals A1 to A3
Terminal A1 and A3 are set to voltage input. Terminal A2 can be used to input either a voltage or a current signal.
Set the signal type as shown in the following table.
Figure 9.29 Location of DIP Switch S1
Terminal Input Signal
DIP Switch Settings Parameters
Switch Setting No. Signal Level
A1 Voltage input - - H3-01
0: 0 V to 10 V/100% (input impedance: 20 kΩ)
1: -10 V to +10 V/-100% to +100% (input impedance: 20 kΩ)
A2
Voltage input

V
H3-09
0: 0 V to 10 V/100% (input impedance: 20 kΩ)
1: -10 V to +10 V/-100% to +100% (input impedance: 20 kΩ)
Current input
I
(Default)
2: 4 mA to 20 mA/100% (input impedance: 250 Ω)
3: 0 mA to 20 mA/100% (input impedance: 250 Ω)
A3 Voltage input S4
AI
(Default)
H3-05
0: 0 V to 10 V/100% (input impedance: 20 kΩ)
1: -10 V to +10 V/-100% to +100% (input impedance: 20 kΩ)
Note:
• To set both A1 and A2 to frequency reference, set H3-02, H3-10 = 0 [Terminal A1 Function Selection, Terminal A2 Function Selection
= Frequency Bias]. Both analog input values will be combined to create the frequency reference.
• To set DIP switches, use tweezers or a jig that has a tip of approximately 0.8 mm.
• To use terminal A3 as a voltage input terminal, set DIP switch S4 to “AI”. The default setting of DIP switch S4 is “AI”.
■ Set Multi-Function Analog Input Terminal A3 to PTC Input
Terminal A3 can be configured either as multi-function analog input, or as PTC input for motor overload
protection.
Use DIP switch S4 to select the input function.
