Conditioner Tab Settings for Three-Stage Valve Drivers
Description Item
(Model 494.16 VD/DUC only) Sets AC excitation frequency that the
conditioner applies to the servovalve’s sensor spool. Excitation Frequency
Sets the amount of peak AC excitation that the conditioner applies to
the servovalve’s sensor spool. Excitation (peak)
Sets the phase for the demodulation circuitry that receives the sensor’s
output. Phase
The sensor’s output rides on the conditioner’s excitation signal, which
is an AC signal. An optimal phase shift yields the maximum DC output
from the conditioner.
Sets the offset applied by the conditioner to the sensor’s output signal. Offset
Sets the amount of gain applied by the conditioner to the sensor’s
output signal. Gain
Gain values affect tuning settings and the noise sensitivity of the valve
command.
Sets the polarity of the spool output or inner loop output signal to
Normal or Invert. Polarity
Polarity cannot be changed when the station pressure is on.
