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 time:
Panel frequency incremental gradient =
Panel frequency decremental gradient =
Set parameters as follows to adjust the output frequency up or down almost in synchronization with the adjustment by
the panel frequency command:

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