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.

RX2 Gain
Program
Frequency
Speed Reference Setpoints
This parameter is used to fine tune the gain 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 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.

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.
