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 does VMN LOW mean on Zapi ACE3 and how can I resolve it?
The VMN LOW alarm on a Zapi Inverter is raised when the motor is running and the power bridge is on, but the motor voltage feedback tested is lower than expected value. Check motor internal connections (ohmic continuity) and motor power-cables connections. If the issue persists, replace the controller.
What to do if Zapi Inverter displays WATCH DOG error?
If you see a WATCH DOG error on your Zapi Inverter, it could be due to: * CAN bus malfunctioning, which disrupts master-supervisor communication. In this case, try switching the key off and then on again. * Wrong contents in the main RAM registers. If this is the case, replace the logic board.
How to fix VDC LINK OVERV. error in Zapi ACE3?
If the VDC LINK OVERV. alarm occurs during brake release, check the line contactor contact and the battery power-cable connection. This indicates an overvoltage condition.
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.
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 causes Zapi ACE3 Inverter to show CONTACTOR OPEN error and how to fix it?
The CONTACTOR OPEN error on your Zapi Inverter means the power contacts do not close. Replace the LC.
What does LOGIC FAILURE #1 mean on Zapi Inverter and how to resolve it?
LOGIC FAILURE #1 on a Zapi Inverter can be caused by: * Undervoltage at the key input (A1). If this is the case, remove external loads like DC/DC converters starting-up, relays or contactors during switching periods, solenoids energizing or de-energizing. * If not, check the battery charge, the battery health and power-cable connections. * If none of these steps work, replace the logic board.
What does POSITIVE LC OPEN mean on Zapi ACE3 and how to fix it?
The POSITIVE LC OPEN error on your Zapi Inverter indicates that the voltage feedback of LC driver (A16) is different from expected. Verify that the LC coil is properly connected and that CONF. POSITIVE LC parameter is set in accordance with the actual coil positive supply. As a last resort, replace the controller.
What to do if Zapi Inverter displays TILLER ERROR?
If the Zapi Inverter displays a TILLER ERROR, check for wrong connections in the external wiring. Verify that inputs are in accordance with the actual state of the external switches and check for a short circuit between A11 and A6. If problems persist, replace the controller.
