Table 2-10: PWM Settings

Settings Description

Gain Speed at which channel reacts to an off-target condition. Decrease to slow down the reaction;

increase to speed up reaction (settings too high can result in oscillation).

Frequency Frequency of the PWM valve drive signal (frequency typically recommended by valve or

motor supplier).

Minimum Duty Cycle Minimumdutycycletowhichthevalvewillrespond,speciedbythemanufacturer.

Maximum Duty Cycle Maximumdutycycletowhichthevalvewillrespond,speciedbythemanufacturer.

Ramp Time Time taken for the control to ramp from minimum duty cycle to maximum. Decrease if the

valve reacts too slowly when off target. Increase if control reacts too quickly (overshooting

target rate).

Dither Preventsvalvefromsticking(speciedbythemanufacturer).

Master Switch Control valve response to all booms (OFF). Hold - Control valve will hold in the same position.

Closed - Control valve will drive full closed and start backup at minimum duty cycle. Resume

- Control valve will close when booms are turned off but will resume at last used duty cycle

setting when booms are turned on again.

Implement Status Control valve response when implement status is open (OFF).

Hold - Control valve will hold in the same position. Closed - Control valve will drive full closed.

Resume - Control valve will close when booms are turned off, but will resume at last used

duty cycle setting when booms are turned on again.

Valve Delay Control delay after turning booms ON from Hold/Resume. When the control valve is set to

close, this feature is deactivated. When Master ON, the valve will delay control for the set

value.
