Terminal A2 Input Signal Selection; Terminal A3 Analog/Ptc Input Selection - YASKAWA AC Drive-A1000 Technical Manual

3.10 Control I/O Connections
n 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.
External Power Supply (V)
12 to 15 Vdc ±10%

Terminal A2 Input Signal Selection

Terminal A2 can be used to input either a voltage or a current signal. Select the signal type using switch S1 as explained in
Table 3.11. Set parameter H3-09 accordingly as shown in
Board on page 67 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 create the frequency
reference.
