VI/II Gain Adjust

Program ⇒ Frequency Setting Parameters ⇒ Speed Reference
Setpoints ⇒ VI/II ⇒ Gain
This parameter is used to fine tune the gain of the VI/II input terminals.
Note: See note on pg. 46
This setting may be used to ensure that the 100% level of the input source (pot,
pressure transducer, flow meter, etc.) is also the 100% level setting of the ASD
system.
This is accomplished by setting the input source to 100% and either increasing
or decreasing this setting to provide an output of 100% from the ASD.

RR Bias Adjust

Program ⇒ Frequency Setting Parameters ⇒ Speed Reference
Setpoints ⇒ RR ⇒ Bias
This parameter is used to fine tune the bias of the RR input terminal when this
terminal is used as the control input while operating in the Speed Control or
the Torque Control mode.
This setting may be used to ensure that the zero level of the input source (pot,
pressure transducer, flow meter, etc.) is also the zero level setting of the ASD
system.
This is accomplished by setting the input source to zero and either increasing or
decreasing this setting to provide an output of zero from the ASD.

RR Gain Adjust

Program ⇒ Frequency Setting Parameters ⇒ Speed Reference
Setpoints ⇒ RR ⇒ Gain
This parameter is used to fine tune the gain of the RR input terminal when this
terminal is used as the control input while operating in the Speed Control or
the Torque Control mode.
This setting may be used to ensure that the 100% level of the input source (pot,
pressure transducer, flow meter, etc.) is also the 100% level setting of the ASD
system.
This is accomplished by setting the input source to 100% and either increasing
or decreasing this setting to provide an output of 100% from the ASD.
RX Bias Adjust
Program ⇒ Frequency Setting Parameters ⇒ Speed Reference
Setpoints ⇒ RX ⇒ Bias
This parameter is used to fine tune the bias of the RX input terminal when this
terminal is used as the control input while operating in the Speed Control or
the Torque Control mode.
This setting may be used to ensure that the zero level of the input source (pot,
pressure transducer, flow meter, etc.) is also the zero level setting of the ASD
system.
This is accomplished by setting the input source to zero and either increasing or
decreasing this setting to provide an output of zero from the ASD.
