RX Gain
Program Frequency  Speed Reference Setpoints
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.
RX2 Bias
Program Frequency  Speed Reference Setpoints
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.

Exciting Strengthening Coefficient
Program Special  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.
Selection for Over Exciting Cooperation
Program Special  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.
