Wigwag Throttle
Set the Li and Lower throttles to match the wigwag voltages. For a 2-wire throttle with the neutral
at the center voltage, typical assignments are in the ensuing table. A voltage throttle is similar, using
the Analog 18 voltage setting versus 2-wire. Notice that the throttle parameters are by percentage,
not voltage.
Throttle/ Region Percentage 0 – 5 Volts 0 – 10 Volts
Lower deadband < 10 % 0.0 – .49V 0 0 – 1.0V
Lower Throttle Command 10 – 45 % 0.50 – 2.25V 1.0 – 4.5V
Middle deadband 45 – 55 % 2.25 – 2.75V 4.5 – 5.5V
Lift Throttle Command 55 – 90 % 2.75 – 4.5V 5.5 – 9.0V
Lift deadband > 90 % 4.5 – 5.0V 9.0 – 10.0V
20. Li rottle settings (from the neutral throttle voltage to the maximum).
Li Min Input = 55%
Li Max Input = 90%
Li Map Shape = 35% (default, adjust for li-throttle response, see Figure 30)
Li_Deadband_Percent = 55%
Li_Oset = 0%
21. Lower rottle settings (from the neutral throttle voltage to the maximum).
Lower Min Input = 45%
Lower Max Input = 10%
Lower Map Shape = 35% (default, adjust for lower-throttle response, see Figure 31)
Lower_Deadband_Percent = 10%
Lower Proportional Driver
22. e lower driver parameter is setup as in the steps above. Assign the Lower_Driver parameter
(CAN Index 0x4FCC 0x00) to the driver operating the hydraulic lower valve, Driver 1. is is
the proportional driver. Set the other driver parameters to match the application following the
valve manufacturer’s ratings. Refer to Figure 28.
23. Complete the wigwag throttle by adjusting the remaining hydraulic throttle parameters as
stated in steps 15-18 (above).
