d6-06: Field Forcing Limit
Sets the maximum level at which the Field Forcing function can boost the excitation current reference. The value is set as a
percentage of the motor no load current. This parameter does not normally need to be changed.
No. Parameter Name Setting Range Default
d6-06 Field Forcing Limit 100 to 400% 400%

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.
No. Parameter Name Setting Range Default
d7-01 Offset Frequency 1 -100.0 to 100.0% 0%
d7-02 Offset Frequency 2 -100.0 to 100.0% 0%
d7-03 Offset Frequency 3 -100.0 to 100.0% 0%
Figure 1.49 illustrates the Offset frequency function.
