1395 DC drive in torque mode

I am running an A/B 1395 in a torque/velocity mode. The greatest integrator controls the output of the drive. Parameter 625 = 4. My problem is and not every drive does this. When I start the drive with 0 torque reference the drive outputs full current. I don't understand why this is happening. I replace the drive and the problem goes away. But I have had this issue with more than one drive. The drive is run in this mode to prevent a negative torque signal from driving the motor in a reverse direction.
