RX2 (AI1) Input Bias
Program
⇒
Frequency
⇒
Speed Reference Setpoints
This parameter is used to fine tune the bias of the RX2 (AI1) input terminal
when this terminal is used as the control input while operating in the Speed
Control mode 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 adjusting this
setting to provide a zero output from the ASD.

RX2 (AI1) Input Gain
Program
⇒
Frequency
⇒
Speed Reference Setpoints
This parameter is used to fine tune the gain of the RX2 (AI1) input terminal
when this terminal is used as the control input while operating in the Speed
Control mode 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 adjusting this
setting to provide an output of 100% from the ASD.
Direct Access Number — F477
Parameter Type — Numerical
Factory Default — 128
Changeable During Run — Yes

AI2 (Option V/I) Input Bias
Program
⇒
Frequency
⇒
Speed Reference Setpoints
This parameter is used to fine tune the gain of the Optional AI2 input terminal
when this terminal is used as the control input while operating in the Speed
Control mode 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 adjusting this
setting to provide an output of 100% from the ASD.
