204-Ref Select Default = Vin1
Range: n/a
Level: 2
Parameter 204, the Ref Select parameter, configures how the reference is determined when the reference source is
configured to terminals.
The following data values may be assigned to this parameter:
Parameter Value Description
Vin1 Vin1 terminal (configured by parameter 205)
Cin Cin terminal (configured by parameter 208)
Vin2 Vin2 terminal (configured by parameter 211)
Vin1 6FS Vin1 terminal with 6x pulse train from an X4, WFC, WF2 drive
Vin1 48FS Vin1 terminal with 48x pulse train from an X4, WFC, WF2 drive
Vin1+Cin Sum of signal at Vin1 and the signal at Cin
Vin1+Vin2 Sum of signal at Vin1 and the signal at Vin2
Vin1-Cin Difference between the signal at Vin and the signal at Cin
Vin1-Vin2 Difference between the signal at Vin and the signal at Vin2
Max Input
{2}
Greatest signal between Vin, Vin2 and Cin
Vin1/Cin DI
{1}
Switch between Vin and Cin using a Digital Input
Vin1/2 DI
{1}
Switch between Vin and Vin2 using a Digital Input
Vin1/KYP DI
{1}
Switch between Vin and Keypad reference using Digital Input
Cin/KYP DI
{1}
Switch between Cin and Keypad reference using Digital Input
Notes:
1. The parameter that sets the function of the designated digital input must be configured as “Ref Switch” to complete the implementation.
2. The “Max Input” option will compare the inputs of all three analog inputs (Vin1, Vin2, Cin) and take the analog input with the highest
percentage input after span, offset, and inversion is applied.
3. When using a 6FS signal, parameter 205 should be set to 0-10V.
205 Vin1 Config
Default = 0-10V
Range: n/a
Level: 2
Parameter 205, Vin1 Config, selects the type of signal for analog input Vin1. Vin1 can be voltage, current, or pulse train
input. This parameter also determines input range, impedance, and characteristics. Use Parameters 206 (Vin1 Offset)
and 207 (Vin1 Span) to customize the selected range. The following data values may be assigned to this parameter:
Parameter Value Description
0-10V 0-10Vdc signal
0-10V Brk W 0-10Vdc signal with broken wire detection for speed pot operation
0-10V I 0-10Vdc signal Inverted
0-10V Bipol 0-10Vdc signal
(5Vdc is stop with 0Vdc Full Rev and 10Vdc Full FWD)
0-5V 0-5Vdc signal
0-5V I 0-5Vdc signal Inverted
0-20mA 250 0 to 20 mA current signal with 250 Ohm load
0-20mA 250I 0 to 20 mA current signal with 250 Ohm load Inverted
4-20mA 250 4 to 20 mA current signal with 250 Ohn load load
4-20mA 250I 4 to 20 mA current signal with 250 Ohm load Inverted
PT 0-1kHz 0 to 1 kHz pulse train
PT 0-10kHz 0 to 10 kHz pulse train
PT 0-100kHz 0 to 100 kHz pulse train
When the signal range is inverted (that is, the minimum input corresponds to the maximum output, while the maximum input
corresponds to the minimum output).
206 Vin1 Offset
Default = 0.00%
Range: 0.0 to 100.0%
Level: 2
Parameter 206, Vin1 Offset, configures the input range (offset) for analog input Vin1 that will affect speed or torque
limit functions. It is expressed as a percentage of the maximum value of the input signal.
Note that if the input signal drops below the offset value or if the input signal is lost (if no offset is configured), fault 22
will be generated.
