5. Check the signal for proper polarity. Observe if the speed command can achieve the minimum and maximum speeds
desired. If not, perform the following:
For 0-10Vdc input (Terminal A1)
1. With no input, adjust Bias (H3-03 setting) until an output of "0.0Hz" is obtained.
2. With full-scale input, adjust Gain (H3-02 setting) until an output of "60.0Hz" (or other desired maximum
frequency) is obtained.
For 4-20mA input (Terminal A2)
1. With 4mA input, adjust Bias (H3-11 setting) until an output of "0.0Hz" is obtained.
2. With 20mA input, adjust Gain (H3-10 setting) until an output of "60.0Hz"
(or other desired maximum frequency) is obtained.
