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.

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
“

”
.

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.
