Determines how aggressively the control valve responds when making rate change adjustments. The
higher the value the more aggressive the response is.
• 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 Flow Offset value can cause the product control system to
not properly control low rates.
Hydraulic Seed Controller Settings for Specific Planters
Note: If you are encountering a problem with skips in the field or if the hydraulic drive is not shutting off
properly, you may need to adjust the Zero Flow Offset settings. For more information, see
“Zero Flow Offset
Variation” on page 161 .
