Troubleshooting
-
Check the connections between the controller outputs and the loads.
-
Collect information about characteristics of the coils connected to the two
drivers and ask for assistance to a Zapi technician in order to verify that the
maximum current that can be supplied by the hardware is not exceeded.
-
In case no failures/problems have been found, the problem is in the
controller, which has to be replaced.
34)
ANALOG INPUT
Cause
This alarm occurs when the A/D conversion of the analog inputs returns frozen
values, on all the converted signals, for more than 400 ms. The goal of this
diagnosis is to detect a failure in the A/D converter or a problem in the code flow
that skips the refresh of the analog signal conversion.
Troubleshooting
If the problem occurs permanently it is necessary to replace the logic board.
35)
DRIVER SHORTED
Cause
The driver of the LC coil is shorted.
Troubleshooting
-
Check if there is a short or a low impedance pull-down between NLC (A16
(A26)) and –BATT.
-
The driver circuit is damaged; replace the logic board.
36)
POWER ACQ. ERROR
Cause
This alarm occurs only when the controller is configured to drive a PMSM and
the feedback sensor selected in the HARDWARE SETTING list is ENCODER
ABI + PWM.
The controller does not detect correct information on PWM input at start-up.
Troubleshooting
-
Re-cycle the key.
-
Check the sensor in order to verify that it works properly.
-
Check the wiring.
-
If the problem occurs permanently it is necessary to substitute logic board.
37)
HOME SENSOR CORR
Cause
The controller detected a difference between the estimated absolute orientation
of the rotor and the position of the index signal (ABI encoder).
It is caused by a wrong acquisition of the angle offset between the orientation of
the rotor and the index signal.
