VDC LINK OVERV.
"This fault is displayed when the
controller detects an overvoltage
condition. Overvoltage threshold
depends on the nominal voltage of
the controller.
Nominal voltage 24V 36/48V
72/80V 96V
Overvoltage threshold 35V 65V
115V 130V
As soon as the fault occurs,
power bridge and MC are opened.
The condition is triggered using
the same HW interrupt used for
undervoltage detection, uC discerns
between the two evaluating the
voltage present across DC-link
capacitors:
- High voltage ) Overvoltage
condition
- Low/normal voltage )
Undervoltage condition"
"If the alarm happens during
the brake release, check the
line contactor
contact and the battery
power-cable connection."

EPS RELAY OPEN
The controller receives from
EPS information about the safety
contacts being open.
Verify the EPS functionality

INIT VMN HIGH
"Before closing the LC, the software
checks the power-bridge voltage
without driving it. The software
expects the voltage to be in a
“steady state” value. If it is too high,
this alarm occurs. The hexadecimal
value “XX” identifies the
faulty phase:
81: phase U
82: phase V
83: phase W"
"1- Check the motor power
cables.
2- Check the impedance
between U, V and W
terminals and -B terminal of
the controller.
3- Check the motor leakage
to truck frame.
4- If the motor connections
are OK and there are no
external low
impedance paths, the
problem is inside the
controller. Replace it."
207
INIT VMN LOW
"Before closing the LC, the software
checks the power-bridge voltage
without driving it. The software
expects the voltage to be in a
“steady state” value. If it is too low,
this alarm occurs. The hexadecimal
value “XX” identifies the
faulty phase:
01: phase U
02: phase V
03: phase W"
"1- Check the motor power
cables.
2- Check the impedance
between U, V and W
terminals and -B terminal of
the controller.
3- Check the motor leakage
to truck frame.
4- If the motor connections
are OK and there are no
external low impedance
paths, the problem is inside
the controller. Replace it."
