◆ About This Product
Installation of the Analog Input Option AI-A3 allows the user to input a high precision, high
resolution analog signal reference to the drive. The option terminals can be set either as
separate functions for each terminal to use the multi-function analog input terminals on the
option for a higher resolution signal, or as a combined input where the drive adds the input
of all signals to the option to build the frequency reference.
The option has an input signal of -10 to 10 Vdc (20 kΩ) or 4 to 20 mA (250 Ω) with three
input channels, DIP switches to select voltage/current input, 13-bit signed (1/8192) input
voltage resolution, and 1/4096 current input resolution.
