u 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. The value is set as a percentage of the maximum
output frequency. They can be selected using digital inputs programmed for Offset frequency 1, 2, and 3 (H1- = 44,
45, 46). The selected offset values are added together if multiple inputs are closed at the same time.
Note: This function can be used to replace the “Trim Control” function (H1- = 1C, 1D) of earlier Yaskawa drives.
Figure 5.43 illustrates the Offset frequency function.
