CONTROLLER MISM.
Cause
The software is not compatible with the hardware. Each controller produced is
“signed” at the end of line test with a specific code mark saved in EEPROM
according to the customized Part Number.
According with this “sign”, only the customized firmware can be uploaded.
Troubleshooting
- Upload the correct firmware.
- Ask for assistance to a Zapi technician in order to verify that the firmware is
correct.
26)
ENCODER ERROR
Cause
This fault occurs in the 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 of milliseconds. This condition is related to an
encoder failure.
Troubleshooting
- Check the electrical and the mechanical functionality of the encoder and the
wires crimping.
- Check the mechanical installation of the encoder, if the encoder slips inside
its housing it will raise this alarm.
- Also the electromagnetic noise on the sensor can be the 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.
27)
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.
28)
WRONG ENC SET
Cause
Mismatch between “ENCODER PULSES 1” parameter and “ENCODER
PULSES 2” parameter (see paragraph 7.2.5).
