What causes a regen timeout on my Vacon Controller?
A regen timeout fault occurs if the Vacon Controller takes more time to decelerate to a stop than is allowed. The timeout is determined by the longest deceleration ramp time (Decel1 or Decel2) plus the Regen Timeout parameter. To resolve this, reduce the amount of regenerative energy or increase the Regen timeout parameter.
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 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.
What does MOL contact fault mean on my Vacon X5 Controller and how can I fix it?
The MOL digital input was activated, depending on pull-up or pull-down logic configuration. To resolve this, reset the MOL contact or remove the condition causing the MOL contact activation.
What causes a drive timed overload on a Vacon X5 Controller?
A drive timed overload occurs when the Vacon Controller senses an overload that exceeds the drive rating. To resolve this, check that load conditions do not exceed the drive’s rating (120% for 60 seconds from nameplate current rating for normal duty and 150% or rated current for 60 seconds heavy duty).
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.
