If your Zapi Inverter displays MOT.PHASE SH., it indicates a short circuit between two motor phases. Verify the motor phases connection on the motor side and on the inverter side, and check the motor power cables. If the problem persists, replace the controller or the motor.
What to do if Zapi ACE3 Inverter shows OVERLOAD?
If the Zapi Inverter displays an OVERLOAD error, it means the motor current has exceeded the hardware limit. Try resetting the alarm by switching the key off and then on again.
What does VMN HIGH mean on Zapi Inverter and how can it be fixed?
The VMN HIGH alarm on a Zapi Inverter is raised when the phase voltages are higher than 10% of the nominal battery voltage. Check motor internal connections (ohmic continuity) and motor power cables connections. If the issue persists, replace the controller.
What does SEAT MISMATCH mean on Zapi ACE3 and how can I resolve it?
The SEAT MISMATCH error on your Zapi Inverter means there is an input mismatch between the traction controller and the pump controller regarding the seat input (A6). Check if there are wrong connections in the external wiring and verify that the seat inputs are in accordance with the actual state of the external switch. If the problem persists, replace the controller.
What does ENCODER ERROR mean on Zapi ACE3 and how can I fix it?
An ENCODER ERROR on your Zapi Inverter means the frequency supplied to the motor is higher than 40 Hz and the signal feedback from the encoder has a significant jump. Check the electrical and the mechanical functionality of the encoder and the wires crimping, as well as the mechanical installation of the encoder. You can also try to replace the encoder or the controller.
What does SPEED FB. ERROR mean on Zapi ACE3 Inverter and how to resolve it?
The SPEED FB. ERROR on your Zapi Inverter means that the absolute position sensor used for speed estimation is moving too quickly. Check that the sensor used is compatible with the software release and the sensor mechanical installation and if it works properly. If the issue persists, replace the logic board.
What does WRONG ENC SET mean on Zapi ACE3 and how to fix it?
The WRONG ENC SET error on your Zapi Inverter indicates a mismatch between the “ENCODER PULSES 1” parameter and the “ENCODER PULSES 2” parameter. Set the two parameters with the same value, according to the adopted encoder.
What does CONTACTOR DRIVER error mean on Zapi Inverter and how to fix it?
The CONTACTOR DRIVER error on your Zapi Inverter means that the LC coil driver is not able to drive the load. Replace the logic board.
What does LC COIL OPEN mean on Zapi ACE3 and how can I fix it?
The LC COIL OPEN error on your Zapi Inverter indicates that no load is connected between the NLC output (A16) and the positive voltage. Check the wiring to verify if LC coil is connected to the right connector pin and if it is not interrupted. If the issue persists, replace the logic board.
What does ANALOG INPUT mean on Zapi Inverter and how can I fix it?
The ANALOG INPUT error on your Zapi Inverter indicates that the A/D conversion of the analog inputs returns frozen values for more than 400 ms. Replace the logic board.
