ADJUSTMENT PROCEDURE:
1.
With no input, adjust Bias (n061 setting) until an output of
0.0 Hz is obtained.
2.
With full scale input, adjust Gain (n060 setting) until an output
of 60.0 Hz (or other desired max. output frequency) is obtained.
NOTE: Follow the same adjustment procedure for other desired frequency setpoints.
n060 :
Analog Frequency Reference Gain
Factory setting: 100 %
Range: 0 to 255 %
Sets the auto-speed frequency command gain,
in increments of 1%.
n061 :
Analog Frequency Reference Bias
Factory setting: 0 %
Range: -100 to 100 %
