Try the routine again and if the fault occurs twice.

Try the routine again and if the fault occurs twice.
What to do if my Vacon Controller displays a ground fault?
If your Vacon Controller displays a ground fault, it means the drive has detected a current imbalance between output phases, indicating current flow to ground. To resolve this: * Check for unbalanced currents. * Check for grounded motor leads or a grounded motor.
What causes an overcurrent condition in my Vacon X5 Controller?
An overcurrent condition in your Vacon Controller can occur if: * The drive sensed an overcurrent condition on power-up. In this case, check for a failed output power device or a shorted motor. * The drive sensed an overcurrent condition during operation because the current has exceeded the safe operation point of power devices. Reduce the load on the motor, verify that the Motor FLA is programmed correctly, and check for mechanical binding and shock loading.
How to fix an over-temperature condition in a Vacon X5 Controller?
An over-temperature condition in your Vacon Controller can be caused by several factors: * The temperature of the heatsink or control board exceeded a temperature limit. Check that the ambient temperature does not exceed the drive’s rating and check for fan operation (assuming the drive has fans installed). * The drive sensed that the heatsink or control board thermistor sensor is faulty or not connected properly. Check the thermistor connections or replace it.
How to troubleshoot communication loss on my Vacon X5?
A communication loss fault occurs when the Vacon Controller is in a serial link control path, and the time since the last Modbus communication exceeds the time set in parameter 903 (SIO Timer). To resolve this: * Check the connections to the Modbus port. * Adjust the value of parameter 903 (SIO Timer) as needed.
What to do if my Vacon X5 shows a low temperature fault?
This fault occurs if the temperature of the heatsink falls below -10.0 degrees C. To resolve this, verify that the ambient temperature is within the drive’s specifications; increase the ambient temperature if necessary.
What causes a stuck key error on a Vacon X5?
A stuck key error occurs if a key press is detected upon power-up, usually due to a defective keypad or someone holding down a key while powering up the drive. Check for a stuck keypad and repair or replace it.
What does a power bridge fault mean on my Vacon X5 Controller?
A power bridge fault indicates that the Vacon Controller detected a failure in the output power devices. To resolve this, check for a failed input power device.
What to do if my Vacon X5 Controller trips due to instantaneous overcurrent?
An instantaneous overcurrent trip can occur if a short circuit was detected on power-up. To resolve this: * Remove the short from the power wiring. * Check for a shorted motor.
What does a checksum error mean on my Vacon Controller?
A checksum error on your Vacon Controller indicates a memory problem when reflashing the drive’s memory, a conflict in the drive’s memory, an inability to write an EE parameter after a parameter change, or too frequent parameter writing through Modbus. To resolve this: * Reset the drive to factory settings. * Slow down the frequency of Modbus writes if parameters are being written too frequently.
