So what exactly do they do when the bus voltage rises during decel ??  Or is there no decel control at all? I've never seen a drive without braking circuitry and DC bus voltage control.

That would be a poor design if no braking resistor causes it to blow up.
Once the bus gets pushed up to its max limit it should let the motor coast
to a stop.

My thought is they probably blow up because they have no braking circuitry
installed, even internal to the drive. Unless it gets added. The gohz seems
to be the same hardware/firmware just from a short scan of the manual.
Wonder if it has a braking circuit.
