217 Trim Ref Enable
This parameter enables or disables trimming of the drive reference by an analog input and selects which
analog input will perform the trimming function.
Speed Reference = Main reference + (Trim % Factor) * (Analog in Percentage) * Max Frequency / 100%

Note that setting a parameter for a Bipolar input value allows trimming both positive and negative around the
reference value.
218 Trim % Factor
This parameter determines the percentage of the analog input signal selected in
Enable, that will affect the reference signal.
301 Min Frequency
Parameter 301, Minimum Frequency, configures the minimum frequency output of the drive. This
parameter governs the minimum frequency when operating from the keypad or from an analog input. The
preset speeds can be set lower than the minimum frequency in parameter 301.
302 Max Frequency
Parameter 302, the Maximum Frequency parameter, configures the maximum frequency output of the
drive.

These parameters configure fifteen preset speeds in addition to the normal reference speed of the drive (as
defined by
set with
different speeds.
The speeds are selected by a combination of four digital inputs (PS1, PS2, PS3, PS4). A wiring scheme
for utilizing preset speeds is provided on page 36 along with a chart showing what combination of inputs
results in the selection of which speeds.
Note that parameter Parameter 303 (Preset Freq1) also serves as the reference frequency for jogging.
