207 Vin1 Span
Default = 100%
Range: 10.0 to 200.0%
Level: 2
Parameter 207, the Vin1 Span parameter, is used to alter the input range (span) of the input signal for analog input
Vin1 that will affect speed or torque limit functions. For example, if parameter 205, Vin1 Config, selects the 0 to 10 Vdc
input signal, setting this parameter to 50% reduces it to 0 to 5 Vdc.
208-Cin Config
Default = 0-20mA 50
Range: n/a
Level 2
Parameter 208, Cin Config, selects the type of signal for analog input Cin. Parameters 209 (Cin Offset) and 210 (Cin
Span) may be used to customize the selected range. The following data values may be assigned to this parameter:
Parameter Value
Description
4-20mA 50
4 to 20 mA current signal with 50 Ohm load
4-20mA 50I
4 to 20 mA current signal with 50 Ohm load Inverted
0-20mA 50
0 to 20 mA current signal with 50 Ohn load load
0-20mA 50I
0 to 20 mA current signal with 50 Ohm load Inverted
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).
209 Cin Offset
Default = 0.0%
Range: 0.0% to 100.0%
Level: 2
Parameter 209, Cin Offset, configures the offset for analog input Cin 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), a fault will be generated.
210 Cin Span
Default = 100.0%
Range: 10.0% to 200.0%
Parameter 210, Cin Span, is used to alter the range of the input signal for analog input Cin. For example, if parameter
208 (Cin Config) selects the 0 to 20 mA input signal, setting this parameter to 50% reduces it to 0 to 10 mA.
211 Vin2 Config
Default = 0-10 V
Range: n/a
Level: 2
Parameter 211, Vin2 Config, selects the type of signal for analog input Vin2. Parameters 212 (Vin2 Offset) and 213
(Vin2 Span) may be used 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
212 Vin2 Offset
Default = 0.0%
Range: 0.0% to 100.0%
Level: 2
Parameter 212, Vin2 Offset, configures the offset for analog input Vin2 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), a fault will be generated.
213 Vin2 Span
Default = 100%
Range: 10.0 to 200.0%
Parameter 213, Vin2 Span, is used to alter the range of the input signal for analog input Vin2. For example, if parameter
211 (Vin2 Config) selects the 0 to 10Vdc input signal, setting this parameter to 50% reduces it to 0 to 5Vdc.
214 Vin1 Filter Time
Default = 20 ms
Range: 0 to 1000 ms
Level: 2
This parameter configures the time constant of a filter for the Vin1 analog input. When the parameter value is set to
0 ms, there is no software filtering of the analog input. A value above 0 ms causes the drive to filter the analog signal.
Note that long filter times will create a delay in the drive response to signal changes.
