MG.10.J8.02 – VLT is a registered Danfoss trade mark
Programmable SyncPos motion controller
However, the drive now reacts somewhat slowly to
changes in velocity, which leads to a deviation from
the set curve at the beginning of the acceleration
phase:
Determining the maximum velocity or maximum
speed
The drive does not achieve maximum speed and
thus starts to brake too late, since it is trying to
catch up with the position reference.
By reducing the velocity to 90% of the maximum
velocity and increasing acceleration and the dece-
leration to 900% the drive can achieve the required
2.47 UU/ms.
