thank you . Is it related to the return voltage from the coil of motor when voltage is removed from motor ? |

It is back EMF of DC motor. Please read this link for more information. Please check the current in r019. During torque reversal when current is too high drive trips on F043. The reason is motor back emf is too high that is why drive injects more current so as to stop motor. But when this current exceeds 100% it trips. HTH. |
