Does the drive give a fault when it coasts? Sounds maybe like it is getting a DC overvoltage when decelerating. If you do have a braking resistor, it may need to be a lower resistance to absorb the power from the motor.
Or, as others have said, it could be a programming option is not set right for deceleration.
