    Hello Sandy thanks for asking Galco today.
    The A10 fault is Overcurrent or Heat Sink Overheated.
    Is the ambient temp under 40C?
    Did this just start to happen all of a sudden?

    Ok next question, does it reset and run, reset and trip again or no reset just stays faulted?

    The drive does reset but trips again as soon as we try to run it, motor doesn’t even move or it just bumps a little if at all

    Sandy it sounds like the output section of the drive has a short in it but it could be the motor. Has the motor been replaced?

    No the motor is original and we don’t have another 1

    Ok then lets do a quick test on the drive. Shut the power off and disconnect the motor from the drive. Use an ohm meter to measure resistance between the 2 + terminals jumped together and the motor terminals U V W. Then do the same thing to the – terminal to U V W terminals. Make sure to check both polarities with the meter leads, ok?

    Olá welintom
    A falha A10 é uma falha de curto-circuito que o inversor está vendo na seção de saída. Para determinar se é o inversor ou o motor, desconecte o motor do inversor e tente executar o VFD aberto carregado. Se o inversor continuar com falha na partida sem o motor conectado, ele será danificado e precisará ser reparado. Se o inversor começar a funcionar e parar de falhar ou apresentar uma falha de perda de fase, isso seria considerado operação normal e o problema deve estar no próprio motor ou na fiação do motor.
