d7: Offset Frequency

Adds or subtracts the set frequency (Offset frequency) to/from the frequency reference using 3 digital signal
inputs, and corrects the speed. Selects the Offset frequency using the terminal set in H1-xx = 44 to 46 [MFDI
Function Select = Offset frequency 1 to 3]. The selected offset values are added together if multiple inputs are
closed simultaneously.
The following diagram illustrates the Offset frequency function.
