Troubleshooting:
- Check the wirings.
- If the motor direction is correct, swap A and B signals.
- If the motor direction is not correct, swap two of the motor cables.
- If the problem is not solved, contact a Zapi technician

WRONG
KEY
VOLT.
Cause:
The inverter key voltage is wrong .
Troubleshooting: Check the battery level if is correct.

ACQUIRI
NG A.S.
Cause:
Controller is acquiring data from the absolute feedback sensor.
Troubleshooting:
The alarm ends when the acquisition is done.
172
ACQUIR
E ABORT
Cause:
The acquiring procedure relative to the absolute feedback sensor aborted.
173
ACQUIR
E END
Cause:
Absolute feedback sensor acquired.

SPEED
FB.
ERROR
Cause
This alarm occurs if the absolute position sensor is used also for speed estimation.
If signaled, it means that the controller measured that the engine
was moving too quick.
Troubleshooting
- Check that the sensor used is compatible with the software release.
- Check the sensor mechanical installation and if it works properly.
- Also the electromagnetic noise on the sensor can be a cause for the alarm.
- If no problem is found on the motor or on the speed sensor, the problem is
inside the controller, it is necessary to replace the logic board.

HOME
SNES.
ERR
XX
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
Troubleshooting
Repeat the auto-teaching procedure.
177
COIL
SHOR.
EB.
Cause
This alarm occurs when an overload of the EB driver occurs
Troubleshooting
- Check the connections between the controller outputs and the loads.
- Collect information about characteristics of the coil connected to the driver 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
