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.
209
PARAM
RESTOR
E
Cause:
The controller has restored the default settings. If a CLEAR EEPROM has been
made before the last key re-cycle, this warning informs you that EEPROM was
correctly cleared.
Troubleshooting:
- A travel demand or a pump request cancels the alarm.
- If the alarm appears at key-on without any CLEAR EEPROM performed,
replace the controller.
210
WRONG
RAM
MEM.
Cause
The algorithm implemented to check the main RAM registers finds wrong
contents: the register is
“
dirty
”
. This alarm inhibits the machine operations.
Troubleshooting
Try to switch the key off and then on again, if the alarm is still present replace the
logic board.
211
STALL
ROTOR
Cause:
The traction rotor is stuck or the encoder signal is not correctly received by the
controller.
Troubleshooting:
- Check the encoder condition.
- Check the wiring.
- Through the TESTER function, check if the sign of FREQUENCY and
ENCODER are the same and if they are different from zero during a traction
request.
- If the problem is not solved, replace the logic board.
212
POWER
MISMAT
CH
Cause
The error between the power setpoint and the estimated power is out of range.
Troubleshooting
Ask for assistance to a Zapi technician about the correct adjustment of the motor
parameters.
213
POSITIV
E LC
OPEN
Cause
The voltage feedback of LC driver is different from expected, i.e. it is not in
accordance with the driver operation.
Troubleshooting
- Verify LC coil is properly connected.
- Verify CONF. POSITIVE LC parameter is set in accordance with the actual coil
positive supply Software, depending on the parameter value, makes a proper
diagnosis; a mismatch between the hardware and the parameter configuration could
generate a false fault.
- In case no failures/problems have been found, the problem is in the controller,
