Matching analog input OI
figure 50 shows the matching possibilities for the 4 to 20 mA
setpoint current. With PNU A103 and A104, you specify the active
current range. In PNU A101, you can set the starting point, and in
PNU A102 the end point for the output frequency. If the line does
not start at the origin, (PNU A101 and A103 > 0), the starting
frequency with PNU A105. As long as the input signal is smaller
than the value entered under PNU A103, either 0 Hz (for
PNU A105 = 00) or PNU A101 (for PNU A105 = 01) is output.
