What does NO CAN MSG. XX mean on Zapi Controller?
To solve the NO CAN MSG. XX error, verify the CANbus network for external issues. If the problem persists, replace the logic board due to a possible internal issue.
What does BATTERY LOW mean on my Zapi DUALACE2 NEW GENERATION Controller and how to fix it?
The BATTERY LOW error on your Zapi Controller indicates that the battery charge is lower than the BATT.LOW TRESHOLD, and the BATTERY CHECK parameter is enabled. To resolve this, first check the battery charge and charge it if needed. If the battery is charged, measure its voltage with a voltmeter and compare it to the BATTERY VOLTAGE reading in the TESTER function. If there's a difference, adjust the ADJUST BATTERY parameter to match the voltmeter reading. If the problem persists, the logic board may need replacement.
Why does my Zapi DUALACE2 NEW GENERATION show FORW + BACK error?
The Zapi Controller shows a FORW + BACK error because both travel requests (FW and BW) are active simultaneously. To fix this: * Ensure that travel requests are not active at the same time. * Check the FW and BW input states using the TESTER function. * Inspect the wirings related to the FW and BW inputs. * Check the microswitches for failures. If the problem continues, the logic board may need to be replaced.
What causes HANDBRAKE error on Zapi DUALACE2 NEW GENERATION Controller?
The HANDBRAKE error on the Zapi Controller is triggered when the handbrake input is active. To resolve this: * Ensure the handbrake is not active by mistake. * Check the SR/HB input state using the TESTER function. * Inspect the wirings. * Check for failures in the microswitches. If the issue persists, the logic board may need replacement.
What to do if Zapi DUALACE2 NEW GENERATION displays CONTACTOR CLOSED error?
If the Zapi Controller displays a CONTACTOR CLOSED error, it means the controller has detected that the contactor is stuck before driving the LC coil. It is suggested to check the power contacts of the LC. If they are stuck, it is necessary to replace the LC.
What to do if Zapi DUALACE2 NEW GENERATION Controller displays CONTACTOR DRIVER error?
If the Zapi Controller displays a CONTACTOR DRIVER error, it indicates that the LC coil driver is unable to drive the load, meaning the device itself or its driver circuit is damaged. This issue is not related to external components, and the logic board should be replaced.
What does FIELD ORIENT. KO error mean on Zapi DUALACE2 NEW GENERATION?
The FIELD ORIENT. KO error on the Zapi Controller means that the error between the estimated Id (d-axis current) and the relative setpoint is out of range. To resolve this, it is recommended to ask for assistance from a Zapi technician to correctly adjust the motor parameters.
What does EVP DRIVER OPEN error mean on Zapi DUALACE2 NEW GENERATION?
The EVP DRIVER OPEN error on the Zapi Controller indicates that the EVP driver (output NEVP, pin A23) is unable to drive the EVP coil, meaning the device itself or its driving circuit is damaged. This fault is not related to external components, and the logic board should be replaced.
What does AUX BATT. SHORT error mean on Zapi DUALACE2 NEW GENERATION Controller and how to fix it?
The AUX BATT. SHORT error on the Zapi Controller means the voltage on the PEB output (pin A27) is at a high value when it should not be. Verify that the POSITIVE E.B. parameter is set correctly according to the actual coil positive supply. If no issues are found, the controller likely has a problem and needs to be replaced.
What does MOTOR TEMP. STOP. mean on my Zapi DUALACE2 NEW GENERATION and how do I resolve it?
The MOTOR TEMP. STOP. warning on your Zapi Controller indicates that the temperature sensor is open (if digital) or has exceeded the TEMP. MOT. STOP threshold (if analog). To resolve this, check the temperature reading from the thermal sensor inside the motor using the MOTOR TEMPERATURE reading in the TESTER function. Also, check the sensor's ohmic value and its wiring. If the sensor is working correctly, improve the motor's cooling. If the warning appears when the motor is cool, the controller may need to be replaced.
