Hi,

i tried to upgrade to mapp Motion 6.6.1 and now my controllers can not communicate with my drives any more.

The logger showas error:  
-1067352818 NCSYS version on the drive not compatible with NC software version; NCSYS version on the drive: 24626

I can not find any dependency notes were i can find what NCSYS i need for mapp motion 6.6.1.

Can i update the NCSYS of my drives, or do i have to step back to an older version of mapp Motion or even exchange the drives?

Best regards,  
Philip

Hello,

Check in the mappMotion with Advanced if the mcAcpSys is in the project. This module contains the device-specific operating systems for ACOPOS drive hardware
