Fault on Drive is "Brake State" fault on controller is "MLS rdy/brk err 2700 SHUTDOWN".
The actual problem after all was that the drive was not initiating the brake and faulting out.
Spoke to Access Electronics and they are 100% sure that it's the LVIB board on the drive acting up, most probably a bad micro relay. (seems to be common issue with these drives) they recommended to ship the drive out to them for a complete overhaul.
Waiting for the drive back so I can confirm the results and close this thread.
Thanks again for all your help Magic Smoke, Vatorgator and Rolly.
