Looking at the online manuals they look like quite impressive drives, which can be configured as digital, analogue or step/dir control with simulated encoder output to motion controller, how are you controlling them for testing? I assume you have the correct cables for the motor PLG connected? It appears all the commutation is done in the drive and just requires the control signal.
Also they can be used in the speed or torque mode, I assume the reason they are running away is that if you do not have an intelligent controller with the simulated encoder output connected. If you try them in the speed mode they may stay stable but would depend on how the trye of control input is configured.
