PARAMETER CHANGE
Parameter Allowable range Description
EVP CLOSE DELAY
(A)
0 s ÷ 12.75 s
(steps of 0.05 s)
It determines the current decrease rate on EVP. The
parameter sets the time needed to decrease the current
from the maximum possible value to zero.
MIN EVP2
(A)
0% ÷ 100%
(steps of 1/255)
This parameter determines the minimum current applied
on the EVP2 when the position of the potentiometer is at
the minimum. This parameter is not effective if the EVP2 is
programmed like an on/off valve.
MAX EVP2
(A)
0% ÷ 100%
(steps of 1/255)
This parameter determines the maximum current applied
to the EVP2 when the position of the potentiometer is at
the maximum. This parameter also determines the current
value when the EVP2 is programmed like an ON/OFF
valve.
EVP2 OPEN DELAY
(A)
0 s ÷ 12.75 s
(steps of 0.05 s)
It determines the acceleration ramp on EVP2. The
parameter sets the time needed to increase the current to
the maximum possible value.
EVP2 CLOSE DELAY
(A)
0 s ÷ 12.75 s
(steps of 0.05 s)
It determines the deceleration ramp on EVP2. The
parameter sets the time needed to decrease the current
from the maximum possible value to zero.
HYDRO SETTINGS
COMBIAC0 has the possibility to drive an AC motor and a DC pump motor
simultaneously, the PARAMETER CHANGE list has these additional parameters
relative to the DC pump control.
HYDRO SETTINGS
Parameter Allowable range Description
DC PUMP
(A)
OFF ÷ ON It manages the DC chopper:
OFF =
Only AC three-phase traction controller (ACE0).
ON =
AC three-phase traction controller and DC pump
chopper (COMBIAC0).
HYDRO PUMP SPEED
(A)
0% ÷ 100%
(steps of 1)
It defines the maximum speed of the hydraulic pump. In
particular, it defines the voltage applied to the pump motor
as a percentage of the maximum voltage.
HYDRO COMPENS.
(A)
0% ÷ 100%
(steps of 1%)
This parameter defines the voltage compensation applied
to the motor when the hydraulic pump is active. The
amount of compensation is a function of the motor current.
Aim of this function is to keep the speed constant in
different operating conditions.
PUMP IMAX
(A)
0% ÷ 100%
(steps of 1%)
It defines the maximum current of the DC pump chopper.
PU. ACCELER. DEL
(A)
0.1 s ÷ 25.5 s
(steps of 0.1 s)
It defines the acceleration ramp for the pump motor.
