298 Firmware Version 6.0
• Fan Speed Calibration
The number of pulses that are generated by the sensor
during one revolution of the spinner dish. The default
setting is 4.
• 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 20.
• 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.
• Zero RPM 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 spinner system to not properly shut
off. The default setting is 30.
Note: See the PWM valve manufacturer information for recommended settings.
• Automatic Control
Checking this box enables closed loop spinner control.
Beginning with the 5.4 display firmware upgrade, checking the Automatic Control
check box exposes a Spinner Icon in the Task Bar that allows user to turn on/off
spinners from the Map Screen. Automatic Control default setting is unchecked.
