HYDRO SETTINGS
Parameter Allowable range Description
PU. DECELER. DEL
(A)
0.1 s ÷ 25.5 s
(steps of 0.1 s)
It defines the deceleration ramp for the pump motor.
MAX SPEED LIFTDC
(A)
0% ÷ 100%
(steps of 1%)
It limits the maximum speed of the lifting function. In
particular, it defines the voltage applied to the pump motor
as a percentage of the maximum voltage.
LIFT DC CUTBACK
(A)
0% ÷ 100%
(steps of 1%)
It limits the maximum speed of the lifting cutback function.
In particular, it defines the voltage applied to the pump
motor as a percentage of the maximum voltage.
1ST PU.DC SPEED
(A)
0% ÷ 100%
(steps of 1%)
It limits the maximum speed of the 1st function. In
particular, it defines the voltage applied to the pump motor
as a percentage of the maximum voltage.
2ND PU.DC SPEED
(A)
0% ÷ 100%
(steps of 1%)
It limits the maximum speed of the 2nd function. In
particular, it defines the voltage applied to the pump motor
as a percentage of the maximum voltage.
PU.DC CREEP SPD
(A)
0% ÷ 100%
(steps of 1%)
It sets the minimum speed for the pump motor. In
particular, it defines the voltage applied to the pump motor
when the Lift SW is closed, as a percentage of the
maximum voltage.
PU.DC COMPENSAT.
(A)
0% ÷ 100%
(steps of 1%)
This parameter defines the voltage compensation applied
to the motor when the proportional lifting function is active.
The amount of compensation is a function of the motor
current. Aim of this function is to reduce, as far as
possible, the speed difference between the loaded and
unloaded conditions.
HYDRO TIME
(A)
0 s ÷ 20 s
(steps of 0.1 s)
(T, TM, TS, CO): in traction configurations, it defines the
time period in that the DC pump motor is left on after the
travel demand has been released.
(P): in pump configuration, it specifies how much time the
AC motor must remain active after the hydraulic request
has been released.
HYDRO FUNCTION
(A)
NONE ÷ OPTION #2 This parameter selects how the pump that enables
hydraulic functions is managed.
NONE = No hydraulic functions is present.
KEYON = ACE0/COMBIAC0 drives a pump motor
from key-on and constantly keeps it on.
RUNNING = ACE0/COMBIAC0 drives a pump motor
only when there is an associated request (for
example a lift request).
OPTION #1 = ACE0/COMBIAC0 does not control a
pump motor, but the truck integrates hydraulic
functions and the ACE0/COMBIAC0 is the master
controller, controlling them through a valve. So the
output that drives the hydraulic valve (for example
EVP) is activated at key-on.
OPTION #2 = Same as OPTION#1, but the valve is
driven only when there is the associated request.
