Terminal A2 Analog Input Signal Selection - YASKAWA A1000 Series Quick Start Manual

3 Electrical Installation
Using External Power Supply (Sink Mode)
The high voltage level of the pulse output signal depends on the external voltage applied. The voltage must be between
12 and 15 Vdc. The load resistance must be adjusted so that the current is lower than 16 mA.

Terminal A2 Input Signal Selection
■
Terminal A2 can be used to input either a voltage or a current signal.
When using input A2 as a voltage input, set DIP switch S1 to "V" (left position) and set parameter H3-09 to 0 (0 to 10
Vdc) or to 1 (-10 to 10 Vdc).
To use current input at terminal A2, set the DIP switch S1 to "I" (default setting) and H3-09 = 2 or 3 (4 to 20 mA or 0 to
20 mA).
To set the DIP switch on the terminal board, use an appropriate sized tool with a tip of approximately 0.8 mm in width.

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.
