Zapi DUALACE2 NEW GENERATION User Manual

AFNZPxxx– DUALACE2 NEW GENERATION – User Manual Page 131/169
The EB driver (pin A28 (A18)) is not able to drive the load. The device itself or its
driving circuit is damaged.
Troubleshooting:
This type of fault is not related to external components. Replace the logic board.
EB. DRIV.SHRT. (MDI/LED code = 40)
Cause:
The EB driver is shorted (pin A28 (A18)).
The microcontroller detects a mismatch between the 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 settings of the EB-related
parameters (see paragraph 8.2.5).
If the problem is not solved, replace the controller.
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.
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.
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 XX
Cause:
The frequency supplied to the motor is above 40 Hz and the feedback from the
feedback sensor has a jump greater than value define by parameter DIAG.JUMP
SENS in few tens of millisecond (see paragraph 8.2.5)Special Adjustment. This
condition is related to an encoder failure.
