Description
After 15 seconds with the motor stalled with the
maximum current, the inverter reduce maximum current
to 50%.
Troubleshooting : Release the accelerator.
Not managed by this software
This alarm occurs when the EPS has detected a steering
angle whereby a reduction on speed truck is requested.
Troubleshooting :
Reduce the acceleration or reduce the steering angle.
The algorithm implemented to check the main RAM
registers finds a wrong contents : the register is "dirty".
This alarm inhibit the machine operations.
Troubleshooting :
Try to switch the key off and then on, if the alarm is still
present replace the logic board.
It occurs when the encoder counting of the main uC is
not matched with the encoder counting of the slave uC.
It is necessary to replace the controller.
Cause :
A) The coil on the aux output is not correctly connected.
B) The smartdriver inside the controller is damaged.
Troubleshooting :
-
It is suggested to check that the coil is correctly
connected between A2 and A4.
-
If no problem is found on the coil. the problem is
inside the controller.
Cause :
The CPOT input red by the microcontroller is not
comprised in the range Vacc_min÷ Vacc_max,
programmed through the "PROGRAMM VACC"
function.
Troubleshooting :
Acquire the maximum and minimum potentiometer value
through the PROGRAM VACC function. If the alarm is
still present, check the mechanical calibration and the
functionality of the potentiometer. If the alarm is not
disappeared the failure is in the ACE logic board, replace
it.
This alarm occurs when an automatic centering is
requested from steady state condition. Then the slave
uC expects the angle measured on the steered wheel
goes into a window from -20 to +20 degrees before the
traction turns moving. In case the traction turns moving
with a steered wheel outside that window, this alarm
occurs. It is necessary to replace the controller.
