Contactor closed
Before driving the MC coil, the
controller checks if the contactor
is stuck. The controller drives the
bridge for some tens milliseconds,
trying to discharge the capacitors
bank. If the capacitor voltage does
decrease by 20% of the key voltage
the alarm is generated.
It is suggested to verify the power
contacts of LC; to replace the LC
is necessary.
Contactor open
The main contactor coil has been
driven by the controller, but the
contactor does not close.
- It could be a problem of the
contacts in the LC that are not
working (does not pull-in), try
replacing the LC.
- If the contactors of LC are
working correctly than the problem
is in the controller, replace it.
LC Coil Open
This fault appears when the no load
is connected between the output
NLC (CNA#16) and the positive (for
eKEY).
- It is suggested to check the
harness, in order to verify if LC coil
is connected to the right connector
pin and if it is not interrupted.
- If, even connecting the coil to the
right pin or replacing it, the alarm
is still present than the problem is
inside the controller logic board,
replace it.
Stby I high
The current transducer or the
current feedback circuit is damaged
in the controller.
This type of fault is not related to
external components so, when it is
present, it is necessary to replace
the controller.
Encoder Error
This fault is signaled in following
conditions: the frequency supplied
to the motor is higher than 40 Hz
and the signal feedback from the
encoder has a jump higher than 40
Hz in few tens mSec. This condition
is related to a malfunctioning of the
encoder.
- Check both the electric and the
mechanical encoder functionality,
the wires crimping.
- Check the encoder mechanical
installation, if the encoder slips
inside its compartment raising this
alarm condition.
- Also the electromagnetic noise
on the sensor bearing can be
a cause for the alarm. In these
cases try to replace the encoder.
- If the problem is still present after
replacing the encoder, the failure
is in the controller.
