H9 ASD Installation and Operation Manual 163

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 met er, 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.
Direct Access Number — F476
Parameter Type — Numeri cal
Factory Default — 128
Changeable During Run — Yes
Minimum — 0
Maximum — 255

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 — Numeri cal
Factory Default — 128
Changeable During Run — Yes
Minimum — 0
Maximum — 255

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.
Direct Access Number — F478
Parameter Type — Numeri cal
Factory Default — 128
Changeable During Run — Yes
Minimum — 0

AI2 (Option V/I) In pu t Gain

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.
