■ d6-03: Field Forcing Selection
Enables or disables the Field Forcing function.
Setting 0: Disabled
Setting 1: Enabled
■ d6-06: Field Forcing Limit
This parameter rarely requires adjustment. Sets the maximum level to what the Field Forcing function can boost the
excitation current reference. The value is set as a percentage of the motor no load current.
◆ d7: Offset Frequency
■ 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- = 44, 45, 46). The selected offset values are added together if
multiple inputs are closed at the same time. The value is set as a percentage of the Maximum Output Frequency.
Note: This function can be used to replace the “Trim Control” function (H1- = 1C, 1D) of earlier Yaskawa drives.
Figure 5.52 illustrates the Offset frequency function.
