3 — PROGRAMMABLE PARAMETERS: Hydraulic Parameters
HYDRAULICS MENU
ALLOWABLE
PARAMETER RANGE DESCRIPTION
Lift Switch Only Enable On/Off When programmed On, closing the Lift switch turns on the DC pump,
Lift_Switch_Only_Enable On/Off at its maximum speed.
OptionBits4 [Bit 4] When programmed Off, DC pump speed varies according to the position
of the hydraulic throttle.
Note: Any time this parameter is changed a Parameter Change Fault
(fault code 49) is set and must be cleared by cycling power; this protects the
controller and the operator.
Lower Switch Only Enable
On/Off When programmed On, closing the Lower switch opens the proportional valve
Lower_Switch_Only_Enable On/Off completely.
OptionBits4 [Bit 5] When programmed Off, the aperture of the proportional valve varies
according to the position of the hydraulic throttle.
Note: Any time this parameter is changed a Parameter Change Fault
(fault code 49) is set and must be cleared by cycling power; this protects the
controller and the operator.
Pump Max PWM
10–100% Defines the maximum allowed armature PWM output during pump operation.
Pump_Max_PWM 3276–32767 Setting the max PWM sets the maximum speed of the pump motor.
Pump Accel Rate
0.1–2.0 sec Sets the acceleration rate of the throttle request to the DC pump.
Pump_Accel_Rate 100–2000 Higher values mean slower acceleration.
Pump Decel Rate
0.1–2.0 sec Sets the deceleration rate of the throttle request to the DC pump.
Pump_Decel_Rate 100–2000 Higher values mean slower deceleration.
Lower Accel Rate
0.1–2.0 sec Sets the acceleration rate of the current request to the proportional valve
Lower_Accel_Rate 100–2000 that controls the lowering function. Higher values mean slower acceleration.
Lower Decel Rate 0.1–2.0 sec Sets the deceleration rate of the current request to the proportional valve
Lower_Decel_Rate 100–2000 that controls the lowering function. Higher values mean slower deceleration.
Load Hold Enable
On/Off When programmed On, the load hold valve is controlled by Driver 4.
Load_Hold_Enable On/Off If your application does not include a load hold valve, set this
Load_Hold_Enable_Bit0 [Bit 0] parameter Off.
Load Hold Delay
0–2048 msec Defines how long the load hold valve is kept open at the end of a lift or lower
Load_Hold_Delay 0–256 action (i.e., after pump speed has reached zero at completion of a lift action,
or after the proportional valve has closed at completion of a lowering action).
The load hold valve is either open or shut, which means it closes abruptly.
To prevent jitter it is important that the delay time be set long enough for the
hydraulic fluid to stop flowing before the load hold valve snaps shut.
The various hydraulics parameters are used to adjust the system’s operating
characteristics—its acceleration, speed, and responsiveness. These parameters
allow the hydraulic system to be tailored to a specific application, or to a specific
operator’s preferences.
