Determines where the control system switches between using Valve Response 1 or Valve Response 2
speed setting.
Leaving all other valve control settings at the default value and making a small adjustment to this setting is
usually all that is required to fine tune system performance.
- Decreasing this value will have the overall effect of speeding up servo valve response.
- Increasing this value will have the overall effect of slowing servo valve response.

• PWM Frequency
Default Value: 100
The frequency that the PWM control valve is pulsed at. Typical settings range from 100 - 125. See PWM
valve manufacturer information for recommended settings.
• PWM Gain
Default Value: 20
This setting determines how aggressively the control valve responds when making spinner speed
adjustments. The higher the value the more aggressive the system response is.
• Zero Flow Offset
Default Value: 30
This setting represents the maximum duty cycle that is sent to the control valve without producing any
hydraulic flow from the PWM valve. Using too high of a Zero RPM Offset value can cause the conveyor to
not properly shut off. See PWM valve manufacturer information for recommended settings.
• Allowable Error
Default Value: 2%
2% - 3% is the normal dead band setting range.
- Too low of a setting value can cause the product control system to continually hunt for the target
application rate.
- Too high of a setting will cause excessive product application error.

• Fan Speed Cal
Default Value: 4
The Fan Speed Cal number is the number of pulses that are generated by the sensor during one revolution
of the spinner dish.
• PWM Frequency
Default Value: 100
The frequency that the PWM control valve is pulsed at. Typical settings range from 100 - 125. See PWM
valve manufacturer information for recommended settings.
• PWM Gain
Default Value: 20
This setting determines how aggressively the control valve responds when making rate change
adjustments. The higher the value the more aggressive the system response is.
