WRONG SET
BAT.

At start-up, the controller checks
the battery voltage (measured at
the KEY input A10) and it
verifies that it is within a range of
±20% around the nominal value.

1- Check that the SET BATTERY
parameter inside the ADJUSTMENTS
list matches with the battery nominal
voltage.
2- If the battery nominal voltage is not
available for the SET BATTERY
parameter inside the ADJUSTMENTS
list, record the value stored as
HARDWARE BATTERY RANGE
parameter in the SPECIAL ADJUST.
list and contact a EP technician.
3- Through the TESTER function,
check that the KEY VOLTAGE
reading shows the same value as the
key voltage measured with a
voltmeter on pin A10. If it does not
match, then modify the ADJUST
BATTERY parameter according to the
value read by the voltmeter.
4- Replace the battery.

253

FIELD ORIENT.
KO

The error between the Id (d-axis
current) setpoint and the
estimated Id is out of range.

Ask for assistance to a EP technician
in order to do the correct adjustment
of the motor parameters.

254

EB. DRIV.SHRT.

1- The EB driver is shorted.
2- The microcontroller detects a
mismatch between the valve
setpoint and the feedback at the
EB output.

1- Check if there is a short or a low
impedance path between the
negative
coil terminal and -B.
2- Check if the voltage applied is in
accordance with the parameters
settings
3- If the problem is not solved, replace
the controller.
