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 STBY I HIGH mean on Zapi ACE3 and how to resolve it?
The STBY I HIGH error on your Zapi Inverter means the sensor detects a current value different from zero in standby. Replace the controller.
What does it mean if Zapi Inverter shows MOT.PHASE SH. error, and how can I fix it?
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 does HOME SENSOR CORR mean on Zapi ACE3 and how to resolve it?
The HOME SENSOR CORR error on your Zapi Inverter indicates a difference detected between the estimated absolute orientation of the rotor and the position of the index signal (ABI encoder). Repeat the auto-teaching procedure.
What does POWER ACQ. ERROR mean on Zapi ACE3 Inverter and how to fix it?
The POWER ACQ. ERROR on your Zapi Inverter means that the controller is configured to drive a PMSM and does not detect correct information on PWM input at start-up. Re-cycle the key. Check the sensor to verify that it works properly, and check the wiring. If the issue persists, substitute the logic board.
What does LOGIC FAILURE #3 mean on Zapi ACE3 Inverter and how to resolve it?
The LOGIC FAILURE #3 error on your Zapi Inverter indicates a hardware problem in the logic board due to high currents (overload). Replace the controller.
What does POWERMOS SHORTED mean on Zapi Inverter and how can I fix it?
The POWERMOS SHORTED error on your Zapi Inverter means the DC-link voltage drops to zero when a high-side MOSFET is turned on. Check that motor phases are correctly connected and that there is no dispersion to ground for every motor phases. If the problem persists, replace the controller.
What causes Zapi ACE3 to show CONTACTOR CLOSED error and how to fix it?
The CONTACTOR CLOSED error on your Zapi Inverter indicates that the contactor is stuck. Verify the power contacts of LC; if they are stuck, it is necessary to replace the LC.
What to do if Zapi ACE3 Inverter displays SHORT CIRCUIT error?
If the Zapi Inverter shows a SHORT CIRCUIT error, it indicates a short-circuit between motor phases. Check that the motor phases are correctly connected and verify that motor phases are not short-circuited. As a last resort, replace the controller or the motor.
