Strange encoder behaviour

[Rok Sabjan <rok.sabjan@cosylab.com>]

Hi!

I'm using the OMS VME58-4E motor controller card and I control the motor 
with an encoder present. The encoder behaves very well. The problem 
occurs, when I take the power from the VME crate. Then the encoder stops 
working. I have to disconnect and reconnect the encoder cables to the 
IO58 module. Then it works as normal.

This problem does not occur at soft nor hard reboot. Only when 
completely powered down.

I use AMO PMK-02-256 incremental encoder.

Does anyone recognise this problem?
