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

Changeable During Run —
Yes
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

Changeable During Run —
Yes

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

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
Torqu
e
Control
or
Speed
Control
settings will determine the rate that
the motor reaches excitation saturation.
