Controller Settings - Pwm; Controller Settings - Servo - Ag Leader EDGE User Manual

- Too high of a setting will cause excessive product application error.
• Control Valve Settings
Displays control valve settings for PWM and Servo Valve Controls. For PWM Valve Control Settings, see
"Controller Settings - PWM" on page 149
on page 149.

Controller Settings - PWM

• Zero Flow Offset
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 the PWM valve manufacturer information for recommended settings. The Default Setting is 30.

Controller Settings - Servo

represents the slow speed of the servo valve. Decreasing the value will cause the servo valve to run slower.
The Default Setting is 8%.
• Response Threshold
Determines where the control channel switches between using Valve Response 1 and 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. The Default Setting is 15.
- 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.
. For Servo Valve Control Settings, see
• PWM Frequency
The frequency that the PWM control valve is pulsed at. Settings
can be found from the manufacturer of the valve. Typical settings
range from 100-125 Hz. The Default Setting is 100.
• PWM Gain
Determines how aggressively the control valve responds when
making spinner speed adjustments. The higher the value the more
aggressive the system response is. The Default Setting is 100.
• Valve Response 1
Determines the speed of the servo valve when product control error
exceeds the Response Threshold setting. Valve Response 1
represents the fast speed of the servo valve. Decreasing the value
will cause the servo valve to run slower. The Default Setting is
40%.
• Valve Response 2
Determines the speed of the servo valve when product control error
is less than the Response Threshold setting. Valve Response 2
