HX7+ ASD Installation and Operation Manual 151
RX Gain Adjust
Program Frequency Setting Speed Reference Setpoints RX
This parameter is used to fine tune the gain 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 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.
Direct Access Number — F475
Parameter Type — Numerical
Factory Default — 141
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 255
RX2 Bias Adjust
Program Frequency Setting Speed Reference Setpoints RX2
This parameter is used to fine tune the bias of the RX2 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 a zero output from the ASD.
Direct Access Number — F476
Parameter Type — Numerical
Factory Default — 99
Changeable During Run — Ye s
Minimum — 0.0
Maximum — 255

Exciting Strengthening Coefficient
Program Special Control Special Parameters
This parameter determines the rate at which the excitation current is allowed to
go from zero to saturation and is enabled at
F481.
Direct Access Number — F480
Parameter Type — Numerical
Factory Default — 64
Changeable During Run — Ye s
Minimum — 0
Maximum — 255
Over-Exciting Cooperation
Program Special Control Special Parameters
This parameter determines the method used to control the rate that the
excitation current is allowed to reach saturation. If Effective is selected, the
preset Torque Control or Speed Control settings will determine the rate that
the motor reaches excitation saturation.
Settings:
0 — Effective
1 — Applied by F480
Direct Access Number — F481
Parameter Type — Selection List
Factory Default — Effective
Changeable During Run — Ye s
