The drive will use 3 digital signal inputs to add or subtract the set frequency (offset frequency) to/from the frequency reference and correct the speed. The drive uses the terminal set in H1-xx = 44 to 46 [MFDI Function Selection = Add Offset Frequency 1 (d7-01) to Add Offset Frequency 3 (d7-03)] to set the offset frequency. When you close more than one input at the same time, the drive adds the selected offset values together.
Figure 1 shows the Offset frequency function:
