This section shall guide you through the most common error scenarios that could occur when using OBLAC Drives.


Make always sure to carefully read through the setup instructions. A lot of issues can be avoided by strictly following the instructions.

Virtualization not activated

If your computer does not have the virtualization technology activated, OBLAC Drives will most likely not work correctly.


To fix that issue, you have to activate the virtualization technology of your processor (VT-x / AMD-V) in your BIOS.

Memory Warning

In rare cases your Linux distribution may show the warning: Not enough physical memory available to power on this virtual machine”


To fix this issue, follow the commands given here

Runtime Issues

One of the most common issues appears directly after installing OLAC Drives. The browser will be opened and the following screen appears:


There are several reasons that will inevitably lead to this problem:

  • you did not power on the drive before starting OBLAC Drives

  • you selected the wrong network port while configuring the VMware settings (check out our Setup Guide)

Other Issues

If the application does not behave properly in any other way than described above, try the following:

  • Refresh the OBLAC Drives web page

  • Make sure no native EtherCAT master is running on the host machine or in the same network

  • Make sure that none of the Synapticon tool components (OBLAC Drives, motion master bridge or motion-master) are already running on the host machine as a native installation

  • If your laptop is connected to a docking station, undock and restart it, then try to run OBLAC Drives again

  • Other installed or running software on the PC is occupying the Ethernet port.

    If possible, stop or uninstall this software or try it with a fresh PC.

  • Not all network adapters are able to perform the real-time requirements for OBLAC drives. In our experience, network cards inside laptops and computers work most reliably. Docking stations (if not connected via USB) are also often reliable.

    A network connection via USB is difficult to predict. Some adapters work very well, others not at all. If USB is the only option, you may have to try several adapters or even a different PC. This is most likely the cause if you can establish a connection to a drive, but the connection is interrupted frequently.

  • Limited performance of the host PC. If the general performance of the PC is too weak (less than 8 GB RAM, low frequency) or too many other software is running on the PC, there is not enough power left for the virtual machine.

    Stop all other software that is running or try with a different, more powerful PC
