Zapi ACE3 User Manual

Page – 106/139 AFFZP0BB – ACE3 – User Manual
Troubleshooting:
- Checks the matching of the parameters between Master and Supervisor.
- Ask for assistance to a Zapi technician.
- If the problem is not solved, replace the logic board.
10) 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.
11) 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.
12) WRONG ENC SET
Cause
:
Mismatch between “ENCODER PULSES 1” parameter and “ENCODER
PULSES 2” parameter (see paragraph 7.2.5).
Troubleshooting
Set the two parameters with the same value, according to the adopted encoder.
13) NO CAN MSG.
Cause:
This is a safety related test. It is a self-diagnosis test that checks the
communication between master and supervisor microcontrollers.
Troubleshooting:
This alarm could be caused by a CAN bus malfunctioning, which blinds master-
supervisor communication
