Adjustment with continuous signals (Parameter setting example 1)
Set parameters as follows to adjust the output frequency up or down in proportion to the frequency adjustment signal input

Adjustment with pulse signals (Parameter-setting example 2)
Set parameters as follows to adjust the frequency in steps of one pulse:
