Start-Up 4 - 16

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.
