d7: Offset Frequency

n d7-01 to d7-03: Offset Frequency 1 to 3
Three different offset values can be added to the frequency reference. They can be selected using digital inputs programmed
for Offset frequency 1, 2, and 3 (H1-oo = 44, 45, 46). The selected offset values are added together if multiple inputs are
closed simultaneously. The value is set as a percentage of the Maximum Output Frequency.
Note: This function can replace the "Trim Control" function (H1-oo = 1C, 1D) of older Yaskawa drives.
