d2-05: Frequency Reference 2 Lower Limit
Sets the lower limit for the frequency reference value that is input from frequency reference source 2 (b1-15). The limit
applies to any source selected in parameter b1-15. The value is set as a percentage of the maximum output frequency.
If a lower reference than this value is input, the drive will run at the d2-05 level. If the drive is started with a lower
reference than d2-05, it will accelerate up to d2-05.

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 if two or all
three 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.
