AF6ZP0CA – COMBIAC0 & ACE0 2uC – User Manual Page – 113/155
Cause:
- The EB driver is shorted.
- The microcontroller detects a mismatch between the valve setpoint and
the feedback at the EB output.
Troubleshooting:
- Check if there is a short or a low impedance path between the negative
coil terminal and -B.
- Check if the voltage applied is in accordance with the parameters
settings (see paragraph 8.2.5).
- If the problem is not solved, replace the controller.
ED SPLIP MISMATCH
(MDI/LED code = 7)
Cause
The control detects a mismatch between the expected slip and the evaluated
one. This diagnostic occurs only if ED COMPENSATION = TRUE.
EEPROM KO
(MDI/LED code = 13)
Cause:
A HW or SW defect of the non-volatile embedded memory storing the
controller parameters. This alarm does not inhibit the machine operations,
but it makes the truck to work with the default values.
Troubleshooting:
Execute a CLEAR EEPROM procedure (refer to the Console manual). Switch
the key off and on to check the result. If the alarm occurs permanently, it is
necessary to replace the controller. If the alarm disappears, the previously
stored parameters will be replaced by the default parameters.
ENCODER D.ERR XX
(MDI/LED code = 3)
Cause:
This alarm occurs only when the controller is configured as PMSM and the
feedback sensor selected is the encoder. The A and B pulse sequence is not
correct. The hexadecimal value “XX” facilitates Zapi technicians debugging
the problem.
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.
ENCODER ERROR
(MDI/LED code = 82)
Cause
This fault occurs when the frequency supplied to the motor is higher than 30
Hz and the signal feedback from the encoder has a too high jump 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.
