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 does broken wire detection mean on my Vacon X5 Controller and how to fix it?
Broken wire detection indicates that the Vacon Controller detected that the potentiometer circuit wiring opened and generated a fault. To resolve this: * Check the wiring for loss of connection to control terminals. * Check that a proper-value potentiometer is installed.
How to troubleshoot a speed reference loss on Vacon X5 Controller?
A speed reference loss fault occurs when the Vacon Controller detects that the analog input was configured to fault if the input current went below the level specified by customer parameters. To resolve this: * Check the physical connections for the reference signal. * Check that the programming for the 4-20 mA signal is correct. * Verify that the signal to the drive is correct.
Why does my Vacon Controller show an overvoltage condition?
An overvoltage condition in your Vacon Controller can occur for several reasons: * The incoming line power is outside of the specified range. In this case, verify the power and add a reactor or transformer to correct it. * There is an overvoltage condition during a running state. Verify the incoming line power and check for a regenerative load. Reduce the Regen load or add dynamic braking resistors. * The drive has detected an overvoltage condition on power-up on the load side. Verify incoming line power is within specification. Add reactor or transformer to correct.
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 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.
How do I fix a keypad loss error on my Vacon X5 Controller?
A keypad loss fault occurs due to a problem with the keypad or its connection, specifically if the drive cannot read any key presses. To resolve this, check the connection from the keypad to the control board. Note that the keypad is not designed for remote mounting without the use of an X5 Remote Keypad option.
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.
What causes a motor timed overload trip on a Vacon Controller?
A motor timed overload trip occurs when the Vacon Controller detects an overload that exceeds the customer’s defined overload setting. To address this: * Check the load current demand. * Verify the Motor FLA is programmed to the correct value. * Verify the TOL characteristic is correct for the application.
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.
