That just shows how little you actually understand about the drives and the technology in them.
The DM542 is using technology that must now be well over 20 year old now, just like Gecko are still using in most of their stepper drives. The only real change to the designs has been to use modern components, but the basics of operation are still the same as 20 years ago. It's just smaller components are used.

AM drives, although officially obsolete within Europe (they were superseded by the EM series), are still an active product produced by Leadshine. They use far newer technology, and monitor how the motor is reacting to the voltage/current applied to it, which is how they implement anti-resonance, auto-tuning, and stall detection. DM/DQ drives do not have that technology in them, regardless of when they were made.
