This parameter configures the time constant of a first-order filter of the Vin1 analog in-
put. When this parameter is a value of 0 ms there is no software filtering of the analog
input. Note that long filter times will create a delay in the drive response to signal chang-
es.
This parameter configures the time constant of a first-order filter of the Cin analog input.
When this parameter is a value of 0 ms there is no software filtering of the analog input.
Note that long filter times will create a delay in the drive response to signal changes.
This parameter configures the time constant of a first-order filter of the Vin2 analog in-
put. When this parameter is a value of 0 ms there is no software filtering of the analog
input. Note that long filter times will create a delay in the drive response to signal chang-
es.
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 Ref. = Main ref.+(Trim % Factor) x value of parameter 217 x 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 Ref. = Drive ref.+ (Trim % Factor) x Max Frequency
100%
Note that setting a parameter for a Bipolar input value allows trimming both positive and
negative around the reference value.
This parameter determines the percentage of the analog input signal selected in Param-
eter 217, Trim Ref Enable, that will affect the reference signal.
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 de-
fault 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
