217 Trim Ref Enable
Default = Disabled
Range: n/a
Level: 2
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 ref (Trim % Factor) * (Analog in Percentage) * Max Frequency / 100%
Parameter Value
Description
Disabled
No trimming of drive reference
Vin1
Value of Vin1 will be used in the calculation above
Vin2
Value of Vin2 will be used in the calculation above
Cin
Value of Cin will be used in the calculation above
Fxd Trim %
Value of Fxd Trim % will be used
Drive Reference = Drive Ref (Trim % Factor) * Max Frequency / 100% / 100%
Note that setting a parameter for a Bipolar input value allows trimming both positive and negative around the
reference value.
218 Trim % Factor
Default = 0.0%
Range: -100.0% to +100.0%
Level 2
This parameter determines the percentage of the analog input signal selected in
, that will affect the reference signal.
301 Min Frequency
Default = 0.0%
Range: 0.0-Max Freq
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
Default: 60 Hz
Range: 0.0 to 400.0 Hz
Parameter
302
, the Maximum Frequency parameter, configures the maximum frequency output of the
drive.

Default: 0 Hz
Default: 2.5 Hz
Default: 7.5 Hz
Default: 15 Hz
Default: 25 Hz
Default: 35 Hz
Default: 45 Hz
Default: 55 Hz
Range: 0.0-Max Freq
Levels 1,2 for 303
Level 2 for 304-318
These parameters configure fifteen preset speeds in addition to the normal reference speed of the drive (as
defined by
)
and the maximum frequency of the drive (as
set with
302, Max Frequency
).
Thus, in effect, you may choose to operate the drive at up to 16
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
also serves as the reference frequency for jogging.
