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
Parameter 217, Trim Ref Enable
, that
will affect the reference signal.
222 Ref Loss Config
Default = No Fault
Range: n/a
Level 2
This parameter allows for the control of the drive’s response to a 4-20mA input on either the Vin1 or Cin input terminals
when the input drops below approximately 3mA. The default value is No Fault. The options for this parameter are:
Retain Spd
Hold the last operating speed
Preset Spd2
Go to the speed programmed at address 304
Fault
Drive faults with an F22 Reference Loss indication
No Fault
Drive does NOT fault; operating frequency drops to the limit set at
Parameter 301, Min Frequency
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.
303 Preset Freq 1 (Jog Ref)
304 Preset Freq 2
305 Preset Freq 3
306 Preset Freq 4
307 Preset Freq 5
308 Preset Freq 6
310 Preset Freq 7
311 Preset Freq 8
312 Preset Freq 9
313 Preset Freq 10
314 Preset Freq 11
315 Preset Freq 12
316 Preset Freq 13
317 Preset Freq 14
318 Preset Freq 15
Default: 5 Hz
Default: 10 Hz
Default: 20 Hz
Default: 30 Hz
Default: 40 Hz
Default: 50 Hz
Default: 60 Hz
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
and
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 41 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.
309 Cut-Off Freq
Default: 0.0 Hz
Range: 0.0 to 5.0 Hz
Level 2
This parameter sets the point where the drive no longer attempts to spin the motor. The range of this parameter is 0.0-
5.0 Hz. When the parameter is configured to a value of 0.0 Hz, the drive will operate with no Cut-off Frequency. If the
function is enabled, the drive will be able to ramp up through the cut-off frequency range, as in normal operation. If the
speed command falls below the cut-off frequency, the drive stops “gating” the outputs and coasts down to zero speed.
The keypad display will indicate Zero Speed, and the Forward or Reverse LED will be lit depending on the command.
When the reference returns to a value greater than the cut-off frequency, the drive will ramp from 0.0 Hz to the reference
frequency.
380 Keeper Input Cfg
Default: Disabled
Range: n/a
Level 2 (Clock)
