What should I do if my Vacon Controller shows an input voltage imbalance?
If your Vacon Controller shows an input voltage imbalance, it means the drive has detected a single-phase condition or a voltage imbalance outside the drive’s rating while running a load that could damage the drive. To resolve this, check the input voltage and current for imbalance, and correct it.
What to do about dynamic brake overload in my Vacon X5?
A dynamic brake (DB) overload in your Vacon Controller can occur due to: * The DB circuit being active on power-up. Check for a failed braking transistor. * The DB circuit being activated for too long, possibly causing the resistor to overheat or fail. Reduce the braking cycle or increase capacity. Activate the current limit. * The DB circuit being overloaded because of too large a regenerative load. Reduce the braking cycle or increase capacity. Activate the current limit.
What causes a low voltage trip on my Vacon X5 Controller?
A low voltage trip occurs if a power dip is detected when the Vacon Controller is operating, and the drive cannot ride through the power dip before shutting off outputs. To fix this: * Verify that the input line power is within the drive’s specifications. * Add a transformer or reduce demands to the power feed.
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.
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.
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.
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.
